How to process eggplant from the Colorado potato beetle. Processing eggplant from the Colorado potato beetle

Process eggplant from colorado potato beetle can large quantity funds.

In the fight against these insects, both chemical and mechanical methods destruction.

The Colorado potato beetle is one of the most dangerous pests of agricultural plants. This insect It feeds on the leaves and fruits of nightshade crops, which include eggplant.
Colorado beetles appear in vegetable gardens with the onset of heat. They often overwinter in the soil, feeding on potato tubers, but they can also migrate from other areas.

It is imperative to fight the pest, because insects multiply very quickly and destroy the crop. Female pests lay eggs 3 times a season, so the insects quickly get used to the blue bushes. If you do not fight pests, then by the end of the season there will be more than 2,000 pests in the garden.

Initially, the beetles eat the leaves, from which the plant draws moisture for growth. As the foliage is destroyed, insects descend on the stem of the bush, gradually destroying it. If timely measures are not taken to combat the Colorado potato beetle on eggplant, the number of pests will increase and the yield will decrease significantly. If the beetles destroy all the leaves of the bush, the plant will die.
On average, an adult pest destroys about 4 grams of plant leaves per month, and its larva eats about 1 gram of leaves.

Methods of dealing with the Colorado potato beetle

You can fight the Colorado potato beetle on eggplant through manual collection, treatment with chemicals and herbal infusions, as well as by manually collecting insects.

Manual collection

Manual collection of pests is relevant only on small areas, because this procedure implies great expense time and effort. This method found to be effective but laborious. It is better to manually collect beetles in the morning and evening.

Salt water is prepared for collection in a container. It is better to use a bucket, so it will be more convenient to collect pests. It is not recommended to touch the insects with your hands, they need to be shaken off the plant with a small broom. This is done carefully so as not to damage the stem and leaves of the bush, which are very weak in eggplant.

After all the insects are collected, they must be destroyed.
When harvesting by hand, it is important to look at the lower leaves of the plant from the back. In these places, beetles lay their eggs so that they do not burn out in the sun. When found, the masonry is crushed.

You can protect eggplant from the Colorado potato beetle with wood ash. For insects, it is poison. To combat and prevent the appearance of pests on the bushes, the leaves are sprinkled with ash.

This should be done after rain or early in the morning, until the dew has dried on the bushes. It is necessary that wood ash stick to the plant, only in this case it can scare away pests. It is recommended to sprinkle with this substance between the rows of blue ones.

You can protect the blue ones from the Colorado potato beetle by spraying with herbal infusions.
Pests are afraid of herbs such as:

• The mustard is yellow.
• Elecampane.
• White acacia flowers.
• Poplar.
• Walnut leaves.
• Celandine.
• Honeysuckle.
• Bed bug.
• Burdock.

To prepare the infusion, any herb is poured with boiling water and infused for 3-4 days, after which it is poured into a spray bottle, which irrigates the garden plot.

The main principle of irrigation is wetting the plant with infusions. In order for the effect to last longer, laundry soap grated on a fine grater dissolves in the finished herbal mixture. It helps to fix the infusion on the leaves of the plant. It is better to irrigate bushes with blue ones in the evenings in calm weather.

Recipes for making herbal infusions for irrigation:

• Mix dry mustard (100 g) and vinegar (100 ml) in 10 liters of water. It is necessary to irrigate during the period active growth plants to prevent insects.
• Fill a third of a 10-liter bucket with celandine leaves, fill with water, boil for 15 minutes, cool and strain. For irrigation, 500 ml of decoction is mixed with 10 liters of water.
• Pour 500 g of dried tobacco roots into 10 liters of water. Leave for 3 days. Strain and mix the infusion with a bucket of water. homemade remedy against insects must be used immediately.
• 100 g of birch tar is mixed with a bucket of water. To eliminate pests, the bushes are irrigated at least 3 times a week.

plant repellent

dry herbs

There are a number of plants that repel Colorado potato beetles with their aroma.
To control pests between blue bushes, it is better to plant:

• Calendula.
• Celery.
• Dill.
• Nasturtium.
• Mustard.
• Matthiola.
• Sagebrush.

Chemicals

You can process eggplant from the Colorado potato beetle not only with herbal infusions, but also with special chemicals.
Preparations for the processing of eggplant a large number of. They are different in composition and spectrum of action. But it is better to give preference to products that contain cypermethrin and imidacloprid. These components are highly effective in pest control.

Popular means:

1. "" - the drug destroys beetles at all stages of insect development. It is enough to use the tool only once a season to protect against pests. "Killer" is not phytotoxic, it works even after rain. Method of dilution: ampoule (1.3 ml) is diluted with 8 liters of water. This amount is enough to irrigate 100 sq. m. garden.
2. "Destroy". Processing means is carried out in early July 1 time. The drug begins to act within an hour after its use. It is allowed to use "Destroy" even at temperatures from +10 to +25 degrees and above. Dilution method: 3 ml of suspension is diluted with 10 liters of water.

Terms of Use chemicals:

• The drug is diluted strictly according to the instructions in the indicated proportions.
• Processing is carried out only in rubber gloves to prevent the product from getting on the skin of a person.
• Irrigation is desirable to carry out in calm and dry weather during the period of active growth of the plant.

Conclusion

You can protect eggplant from the Colorado potato beetle by covering the bushes with a fine mosquito net. This method is effective during fruit setting on the bushes, when the use of chemicals is not recommended.

To prevent the appearance of pests, you need to alternate crops in the garden. Blue is allowed to plant in one place 1 time in 4 years. Pests can stay in the soil for up to 3 years, so after pulling out eggplant seedlings, it is better to plant flower crops in their place that do not attract insects so much.

Eggplant is also called nightshade dark fruit refers to perennial herbaceous plant but we grow it as an annual. Only the fruit is used for food. For botanists it is a berry, in cooking a vegetable. Seedlings from 40 to 1.5 meters high. The eggplant fruit has a rounded, cylindrical, pear-shaped shape. Leaves are rough, prickly. Does not love low temperatures, moisture-loving. For open ground it is desirable to choose early maturing species With high yield.

What is eggplant vegetable

Very pleased with the carpal variety "Joker" it has a high yield on a branch, not the traditional one fruit, but 4-5 pieces, it will please you with a bright purple color. In height, the bush grows more than a meter and therefore it is not recommended to grow it without support. The fruits are elliptical in shape, the skin is thin, the pulp is white, dense, excellent in taste.

Variety "Vakula" the result of Russian breeders. Growth from 1.2 to 2.2 meters with an increased yield of 12 kilograms with square meter. Fruit dark purple weight 100-400 grams with white flesh. "Sancho Panza" this is mid-early variety. The yield is excellent, the fruits are 900 grams of spherical shape. Violet color, white flesh of excellent taste. Super early, maturing eggplant "Negus" from germination to maturity 70-90 days. Bushes compact 50-60 centimeters. Fruits 150-300 grams rounded. Has a purple color.

Landing

Eggplants that came to us from the southern regions are thermophilic. The temperature is not lower than plus 20 degrees. They do not like lack of moisture. Prefer abundant lighting. The soil is preferred loose, light, fertile. They grow well in the beds after onions, carrots, legumes, melons. They do not like it when they are planted in places where tomatoes and peppers grew. It is recommended to plant in one place, once every three years. Preference is given to peat and humus.

Sowing of seeds is carried out from February to March in boxes at a temperature of plus 25 degrees. Treat loose soil before sowing with boiling water with the addition of potassium permanganate, or with the addition of fertilizer "Effecton" . Eggplants have rather large seeds, therefore, in order to avoid picks, you can lay them out one at a time during sowing. But if the seedlings are thickened, then with the appearance of 4-5 true leaves, it is recommended to dive. Under open sky we start planting when the threat of frost does not threaten, the temperature at night is not lower than plus 15. The distance between seedlings is at least 30 centimeters.

Care

More often you need to loosen the soil, not to allow it to become hard, rigid. Avoid drying out, abundant watering, preferably with heated water. Provide three single top dressing per season, prefer slurry, but can be replaced with fertilizers. Weeds are systematically removed and monitored for pests. It is desirable to spud bushes.

Let's talk about diseases and pests. In order for the eggplant leaves not to turn yellow, we add nitrogen 20 days after planting. The leaves are curling, this indicates a lack of sunlight, improper care(watering), or the presence of pests. If the bushes grow slowly, it is worth making nitrogen fertilizers. With mass greenery and poor harvest - potassium. Spray with low flowering boric acid. The biggest nuisance for eggplant is the Colorado potato beetle.

Rescue, fight and protection of eggplant from the Colorado potato beetle

The Colorado potato beetle is very fond of eggplant leaves, but can also get to the fruit. When growing eggplants on the site, you need to have tremendous patience in the fight against this enemy. The problem, when the ovary appears on the plants and it is no longer possible to use poisons, becomes especially acute. In this case, it will only be possible to manually collect the pest.

First, let's try to prevent the appearance of a beetle. During planting, you can try to hide the seedlings under plastic bottles. The Colorado potato beetle is a lazy creature, especially in summer period. It will be difficult for him to climb the slippery surface of the bottle. But, unfortunately, this method will secure for a while, while the seedlings are small. When our little blue ones reach an impressive size and it's time to remove the plastic bottles, we recommend processing the plants "Aktofit". We breed according to the instructions attached to the pesticide.

We must not forget that the Colorado potato beetle adapts very quickly. In the fight against him, you need to remember that it is best to use each time different kind poison. Let's talk about the most effective ones today. The discovery of the century was the drug "Fitoverma" penetrating the body of beetle larvae, it provokes paralysis and death within nine hours. Serves as an exterminator for bugs "Bovyrin" , contains spores of the muscardine fungus, (excites fungal diseases in insects).

The drug will be effective "Agravertin" second title "Akarin" , alcohol tincture fungus from the soil. A chemical drug acts quickly on the Colorado potato beetle "Shar Pei" . This quick action kills the beetle on different stages development. Only 20 minutes and no pest. A drug "Dilora" will kill both beetle larvae and adult specimens.

Whichever drug you choose, REMEMBER! All poison must be diluted according to the attached instructions. Fight to produce in sunny, dry, calm weather. If after processing during the day it started to rain, consider that your work has gone down the drain. Don't forget about your own security measures. Before using pesticides, we advise you to drink a glass of jelly. The jelly-containing starch coats the stomach, thereby protecting it from the harmful effects of the pesticide.

Don't forget to take your pills activated carbon at the rate of two tablets for every ten kilograms of weight. We protect our hands with rubber gloves. A respirator is required on the face, if not, then at least a gauze bandage. After working with poison, be sure to drink a glass of milk, or any dairy product. Milk neutralizes poison.

Important to remember! Colorado beetle - very dangerous pest requiring constant monitoring of treatments. One female lays 50 larvae at a time, there is not always time to regularly collect such an amount of the enemy. To help the poisons, plant the Colorado potato beetle around the chosen crops, natural repellers: calendula, marigolds, dill, nasturtium, matthiola.

Important to remember! No matter what means of protection against the invasion of unwanted guests you use. It is necessary to inspect the plant in a timely manner. When you see the first signs of damage on the leaves, immediately look for the pest. Try to prevent reproduction by all means at hand.

The most dangerous pest of the blue ones is the Colorado potato beetle. But it can be effectively dealt with. different ways with and without chemicals.

Briefly about the pest

The potato leaf beetle was first discovered as a species in the 20s of the 19th century in western North America. There he lived on wild nightshades. And this beetle began to be called the Colorado beetle in the 1860s, after it destroyed potato plantations in the state of Colorado. Pests were brought to Europe with vegetables more than once, but at first the outbreaks appeared small and they were able to be destroyed.

But during the First World War, the Colorado potato beetle was introduced into Western Europe and from here in a couple of decades flew to the territory Soviet Union, massively spreading in the 50-60s. These insects flew to new territories with the winds (even without wind they fly at a speed of 8 km/h, and the wind only increases the speed) and came along with vegetables. But after which vegetable you can plant carrots, and how to choose the right vegetables, this will help you understand

On the video - information about the pest:

Beetle females are very prolific: offspring are laid three times per season. Each clutch contains about 700 eggs. For the winter, these beetles hide deeper into the ground and sleep there until spring, enduring frost. And in the spring they get out and look for food, giving preference to nightshade.

Colorado beetles are voracious: in a month, an adult eats 4 g of leaves, and larvae - 1 g. If you do not fight them, then it is not realistic to get a good nightshade crop.

Chemistry on guard of the harvest

Most of the preparations that are used to treat potatoes from the Colorado potato beetle are also suitable for eggplant. For example, the Prestige insecticide of the German manufacturer Bayer has proven itself very well. This is a concentrated emulsion, it goes on sale in 60 ml bottles. But what is the Prestige means for processing potatoes, indicated in the article by reference.

There are two active ingredients in the preparation:

1. Imidacloprid.
2. Pentsicuron.

Also in the composition there are growth stimulants, due to which the yields increase. Active components are valid for 40-50 days. And then they break up and do no harm to human health.

Using the drug is simple:

1. Dilute the emulsion at the rate of 1 ml of prestige per 100 g of water and soak the seedling roots for 8 hours in the solution.
2. After 8 hours, plant seedlings and you can forget about Colorado for one and a half to two months. During this time, the plants will strengthen, fade and bear fruit.

There are a lot of chemicals that are effective in the fight against the Colorado potato beetle, each gardener chooses for himself. "Intavir", "Kinmiks", "Decis", "Sonnet", "", "Artelik", "Taran" have proven themselves well. Each of them must be used according to the instructions.

Treatment with chemicals should be carried out before the flowering of the plant. In the future, if there are already fruits, it is dangerous to use insecticides for health.

How to do without chemistry?

Although this is quite laborious, “blue ones” can also be grown without chemical treatment. The most effective ways:

On the video - how to process eggplant from the Colorado potato beetle:

Also, the method of spraying eggplant bushes with mustard has proven itself very well. Dry mustard powder 100 g is mixed with 100 g of table vinegar and the mixture is diluted in a bucket of water (10 l). This solution is sprayed on each bush. It will be necessary to process twice: at the beginning of the growing season and in the case when you notice an increase in the number of the Colorado potato beetle on the site.

It will also be useful to learn about what exists, and how exactly it can be applied for the best result.

The Colorado potato beetle is one of the most dangerous enemies eggplant. This pest can severely damage plants and significantly reduce the yield of "blue". That is why, when planning to start growing this crop, many gardeners first of all ask themselves the question, How to protect eggplant from the Colorado potato beetle.

Of course, you can simply generously treat the plantings with special chemicals that destroy insects, but in this case, the eggplants themselves will absorb some of the poisons, which is very undesirable. With this in mind, summer residents from year to year invent new ways to deal with "blue" pests.

Features of Colorado beetles

In a suitable climate, Colorado potato beetles reproduce very quickly and can develop up to 3 generations in one season. These insects endure cold quite stubbornly - usually almost 60% of adult pests survive the winter, which during this period hide in deep layers of soil, where they are not afraid of frost.

Larvae with a strong drop in temperature die, but adults survive enough to breed a new generation of bugs with the first heat.

The female Colorado potato beetle can lay up to 700 eggs in one season, which she places on the underside of plant leaves. The larvae grow for 30-35 days, then the insects remain in the pupal state for another 1-2 weeks, after which adult beetles appear. During the season, the population of pests that survived the winter can increase 200 times.

Methods of dealing with Colorado potato beetles

There are many folk methods for protecting eggplant from Colorado potato beetles, which bring very good results. Of course, such measures are less effective than purchased insecticides, but they allow you to grow truly organic vegetables. Among the ways to deal with these pests, it is worth highlighting:

Collection of beetles and larvae

Manual collection of Colorado potato beetles and their larvae is the oldest method of insect control. During the entire growing season of eggplant, gardeners regularly inspect plants for pests and their eggs, collect the found beetles in special containers, and then destroy them.

The disadvantage of this method is that it is very time consuming and therefore only suitable for small plantations.

Plant dusting

In protecting eggplant from Colorado potato beetles, dusting of sifted plantations has proven itself very well. wood ash, which acts on insects like a poison.

It is recommended to pollinate plants in the early morning or after rain, because during this period the leaves are still wet and the ash settles well on them. Ash should be used at the rate of 10 kg per 1 weave of land. Before flowering, eggplants need to be pollinated 1 time in 2 weeks, and after - 1 time per month. To increase efficiency, you can sprinkle the aisles with ash.

Plants can also be sprinkled with cornmeal. In this case, the beetles, along with the foliage, also eat pieces of corn, which swells in their stomachs, which leads to the death of insects. This dusting should also be done when the leaves are wet.

Many gardeners enhance the effect of dusting by pouring birch or pine sawdust into the aisles. The smell of fresh wood repels the Colorado potato beetles and they do not attack plantings so actively.

Spraying eggplant with herbal infusions

Good results in the fight against Colorado potato beetles are shown by spraying eggplants with infusions and decoctions of their herbs. Using this method correctly, you can reduce the insect population several times and increase the chances of getting good harvest"blue". Used to prepare decoctions various plants, among which:

• garlic;
• walnut (leaves and shells of nuts);
• white acacia;
• celandine;
• dandelion;
• onion peel;
• sagebrush;
• tobacco, etc.

To obtain a solution, the plants are soaked hot water and insist for several days. In order for the decoction to settle better on the leaves, liquid or laundry soap, grated on a fine grater, is added to it.

Plants are abundantly sprayed with the finished infusion in calm and warm weather, when the eggplant leaves are completely dry. It is recommended to use such decoctions in the evening, because under the influence of sunlight they quickly lose their properties.

Despite the fact that herbal infusions are considered environmentally friendly, it is best to bury their remains outside the garden and wash your hands thoroughly after using them.

Planting Repellent Plants

Colorado beetles are very sensitive to the smells of plants that are inedible for them, which is what many gardeners use. So, insects are repelled by aroma:

• marigolds;
• calendula;
• cucumber grass;
• coriander;
• nasturtiums;
• matthiols;
• wormwood.

By planting these plants between the rows, you can significantly increase the protection of eggplants from Colorado potato beetles.

Creating Insect Barriers

Many summer residents try to protect eggplants from Colorado potato beetles, complicating access to plants. So, they build special shelters for plantings from a fine mosquito net: it does not allow insects to get to the leaves, without shading the “blue” ones and without blocking watering. For this purpose, cut plastic bottles are also used, which cover each eggplant bush.

When wondering how to process eggplant from the Colorado potato beetle, you should first study folk methods which show quite good results. But keep in mind that they can be used on relatively small plantations and with not very mass destruction plants by insects. If there are a lot of beetles, and the planting area is impressive, then it will be more effective to resort to chemical preparations.

Thus, it implies their protection from pests, which, in turn, allows you to collect the maximum yield of this vegetable.

Every gardener who grows eggplant on his plot knows that the Colorado potato beetle is the main pest of the crop. Therefore, it is important to carry out the processing of plants in a timely manner in order to protect the future harvest. But, before taking any action, you should find out how to process eggplant from the Colorado potato beetle, and what drug or remedy to use so that the fruits retain their beneficial properties.

Signs of defeat

The attack of the pest occurs almost immediately after planting the nightshade seedlings on permanent place in open ground or a greenhouse.

Find out who persistently eats eggplant in the greenhouse and on open area can be on the first signs:

• damaged leaves along the edge;
• growth retardation;
• the presence of adults of the Colorado potato beetle in a small amount.

How to process eggplant from the Colorado potato beetle

Initially, the pest feeds on the pulp of the leaf from the back, but as it grows and reproduces, it moves upward, actively eating everything in its path.

Important! Damaged eggplants lag behind in growth, cease to fully develop and are distinguished by an oppressed appearance.

With further reproduction, the pest can be identified by the characteristic clutches of eggs, which are distinguished by a bright orange color, which are localized on reverse side leaves. Their appearance indicates that new individuals will appear within a week.

The need to fight

The Colorado potato beetle is a dangerous pest that is distinguished by voracity and endurance. Therefore, if you do not take necessary measures to save plants from its invasion, then the eggplant harvest can never be expected.

The most dangerous are young individuals of the pest, which, at the stage of active growth, feed on leaves around the clock, causing damage to plantings.

Note! After the destruction of one plant, these bugs move to the next one, and so on, until all nightshade plantings are completely destroyed.

Therefore, it is important to start the fight against the pest in a timely manner in order to prevent its further uncontrolled reproduction and to protect the future eggplant crop from the re-invasion of the Colorado potato beetle.

How to get rid of a pest

To protect eggplants during the growing season and secure plantings in the future, complex control methods are used. This is due to the special endurance of the pest and its resistance to the drugs used. Therefore, the processing of plants is carried out several times during the season. In this case, you should figure out how to properly protect eggplant from the Colorado potato beetle, starting from the stage of development of the bush.

Chemicals

Chemical pest control

To protect eggplant plantings immediately after landing in a permanent place, experienced gardeners recommend watering the plants with special preparations. This will protect the young bushes and make it possible to fully take root in a new place.

On a note! For processing, you can use drugs such as Prestige, Masterpiece. It should be carried out with a working solution, not exceeding the dosage of the component specified in the instructions for the product.

The second stage of processing should be carried out during the active growing season, which will create protection and help protect eggplant from a massive pest invasion. In this case, it is recommended to spray the plants on the leaf using any of the proposed preparations:

• Intavir;
• Decis;
• Aktar;
• Karate zeon;
• Presto;
• Twix.

The last stage of processing is carried out during the period of flowering and the formation of the ovary. This will help rid the eggplant bushes of the young pests that have appeared and prevent their further reproduction. During this period, you can spray the plants with similar preparations, as in the previous treatment, but choosing a different remedy.

Important! In August, when eggplant bushes enter the fruiting stage, you can save them from the Colorado potato beetle by spraying them with biological preparations, the main condition of which is short term waiting before harvesting: Aktotsid, Aktofit, Fitoverm.

Folk remedies

You can fight the pest on eggplant not only with the help of chemistry, but also with folk remedies. You can cook them at home using improvised ingredients:

• Wood ash. The pest does not tolerate this component, so you can save the planting by dusting the plants. It is necessary to do the procedure after rain or in the morning due to dew, since it is important that the bushes are wet and the ash lingers on the leaves.
• Herbal infusions. They are prepared from such components: garlic, onion peel, wormwood, celandine, tobacco, black locust. To prepare the product, you need to pour 1 part of the collection with 2 parts hot water and leave for 24 hours. Before spraying the leaves, add a little grated laundry soap, which will improve the adhesion of the product to the leaves.

Preparing homemade spray solution

Note! Apply folk remedies necessary at the first sign of damage to the bushes, since to save the plantings during the mass invasion of the Colorado potato beetle without chemicals fail.

collection of beetles

A safe method of control is manual collection of insects. But you can use it if the site is located directly near the house, since this procedure is carried out daily after the first signs of the pest appear.

The collection is carried out in a specially prepared container filled with salt water. The method is considered effective, but too laborious, as it requires additional effort and daily time. The collection of the Colorado potato beetle with a mass accumulation should be carried out 2-3 times a day, and it will not be possible to completely get rid of the pest in this way.

Prevention

Many gardeners prefer not to fight, but to carry out comprehensive prevention from eggplant damage by the Colorado potato beetle.

To do this, several methods of struggle are used:

• Repellant plants. You can scare away the pest from the eggplant beds with the help of crops such as calendula, marigolds, celery, dill, nasturtium, mattiola.
• Plastic bottles. You can save seedlings in this way until the bushes grow much. To do this, cut off the bottom and top of the bottle, and then put a cap on each plant.
• Fencing. As a defense, you can use mosquito net or polyethylene, protecting the plantings with a special fence 50 cm high. This method is based on the fact that the Colorado potato beetle moves along the ground.

Which method of dealing with the Colorado potato beetle to choose, each gardener decides for himself. But you should not ignore the problem, otherwise the harvest may not come.
