  5. To use an effective and harmless biological method for combating scoops – a trichogram predator that destroys pest eggs. During the laying period, the three-time release of bronchograms (30–40 thousand animals per 1 ha with each release) should be carried out with an interval of 5–6 days.
  6. Chemical preparations are effective against caterpillars scoop: Decis, 2,5% to. Z. – 2 ml per 10 l of water; Arrivo, 25% ke on 10 l of water; Sherpa, 25% ke – 1.5 ml per 10 liters of water. When working with insecticides, try to prevent them from reaching other areas and crops, strictly observe the waiting time (the number of days from processing to harvest) specified in the instructions.
