PROBLEMS OF BIOLOGICAL PROTECTION OF COTTON CROPS FROM PESTS

Abstract

This article presents the results of studies of biological measures of protection of cotton against cotton scoops in the conditions of the Myrzashol district of the Turkestan region. The relationship between phytophages and entomophages in cotton crops was clarified, and the biological effectiveness of Trichogramma, goldeneye, and gabrobragon against eggs and worms of the cotton scoop was determined. Studies have shown that the biological effectiveness of bioagents with a working flow rate of 500 pieces of gabrobragon, goldeneye, 1 gram of trichogram against cotton moth was 46.4%; 44.1%; 46.6%. These bioagents have proven to be very effective in the fight against the young cotton butterfly on cotton. From an economic point of view, the use of biological treatment works provides an increase in productivity and cost recovery, and also have a great advantage - they do not pollute the environment.
