Summer is the height of the dacha season. The harvest of vegetables and fruits depends on the quality of the effort expended. During the growing season of garden crops, especially nightshades, gardeners have to expend effort in different directions:

The last point is very familiar to those gardeners who have potatoes, eggplants or tomatoes planted on their plot. The appearance of the Colorado leaf beetle in garden beds creates many problems.
He eats the leaves of not only the above-mentioned crops, but is also quietly content with sweet peppers, physalis, and petunia. Summer residents consider the pest a real disaster on the site.
If the size of the plantings is very small, many people collect adult individuals by hand, but this does not save the area from the pest. Special preparations are more effective - insecticides, which can reliably rid the beds of the annoying leaf beetle. Insecticides are toxic chemicals used to control harmful insects. One of the new effective means is the Kalash insecticide.
