Summer is the height of the summer season. The quality of the effort expended depends on the harvest of vegetables and fruits. During the growing season of garden crops, especially nightshade ones, summer residents have to expend efforts in different directions:
- comply with agrotechnical requirements;
- carry out preventive measures;
- fight diseases and pests.
The last point is very familiar to those gardeners on whose plot potatoes, eggplants or tomatoes are planted. Many problems are created by the appearance of the Colorado leaf beetle on the beds.
He eats the leaves of not only the above-mentioned crops, but is also calmly content with sweet pepper, physalis, petunia. Summer residents consider the pest a real disaster on the site.
If the size of the landings is very small, many people collect adults by hand, but this does not save the site from the pest. Special preparations are more effective – insecticides that can reliably rid the beds of the annoying leaf beetle. Insecticides are chemical poisons used to control harmful insects. One of the new effective means is the Kalash insecticide.
