Operating principle
The drug refers to insecticides with intestinal contact effects on insects. If the pest enters the intestines or skin, death occurs within 3-4 hours.
Frequent use of Karbofos is addictive and reduces effectiveness. Insects produce an enzyme that can destroy the structure of malathion and weaken its effect.
The product also affects beneficial insects, bees and bumblebees that pollinate the plant, and is also dangerous for fish. Therefore, in order not to reduce their numbers, treatment with Karbofos is not carried out during active flowering of crops. It is recommended to spray the drug at a distance of 5 km from the location of the apiary and reservoirs.

Karbofos from a glass case on currants is used during the active blooming of foliage, at an air temperature of 15 0C and above. Spraying is carried out in 2-3 stages with an interval of 14 days until the berries are completely ripe.
Experts recommend processing currants in sunny, windless weather in the morning or evening. The leaf is generously coated with the product so that the drug is absorbed into the walls of the insect.
