At the same time, if it is better to fumigate a garden with lingonberries from flower beetles in windy weather, then from a codling moth with a leafworm - on the contrary, you need to choose the most calm day so that the smoke can envelop the entire garden and does not disappear from the site too quickly.

In pest control, green manure can also be used (though mostly not “weedy”). So, for example, if on the beds after harvesting the main crop, sow white mustard or rye, the number of wireworms is significantly reduced, and green mass perennial lupine toxic to the Colorado potato beetle.
