Tyumen agronomist Ivan Grigoryev called the methods of combating the Colorado beetle, which is the main pest of potatoes.
According to the expert, many summer residents use preparations for pre -sowing etching before planting. As a rule, this gives an effect. However, sometimes the beetle survives and develops on processed landings. The agronomist explains this by the stability of the pest to the drug. Also, the duration of the drug is limited and, after its completion, the beetle can settle on the tops of potatoes.
On a small field, you can manually collect larvae, adult individuals and eggs. However, otherwise the help of insecticides will be needed. The agronomist advises chemicals, for example, Imidor or Aktara. When using them, it is necessary to observe safety and dosage.
It is necessary to change the drugs every two to three years so that the pest cannot get used to them, writes aloud.ru. Also, when buying insecticides, the agronomist recommends paying attention to the active substance, and not to the trade name.
Another way to combat the beetle is biological drugs that are harmless to people and the environment. You can use Bitoxibacillin or Fitoverm. He will not save the landing from adult beetles, but he will kill the larvae.
