A drug used to defoliate cottonseed midges, which is absorbed by the plant leaves within 12 hours. The first effect of the drug is visible 2-4 days after treatment. The drug accelerates the division of plant cells, as a result of which the leaves begin to fall off while still green (without drying). The drug also prevents the growth of new leaves, accelerates the natural ripening of unopened buds, and does not harm the quality of the crop.
