Plant diseases and pest insects are among the main constraints affecting the production and productivity of crops both in terms of quality and quantity. Use of chemicals continues to be the principal activity to mitigate the negative impacts of chemical plant protection. The environmental concerns, health conscious attitude of human beings and other hazards associated with the use of pesticides and using of biological means to control of the crop pests is gaining importance. Biological control involves the use of large spectrum of beneficial organisms and their products (biological active substances, useful microorganisms and viruses, entomophages), that reduce the negative effects of pests and promote positive responses by the plant. In our institute, over several years, a number of commercial products based on different viral, fungal and bacterial antagonists have been registered. These commercial products include, Virin-HSP, on the Nuclear Polihedrosis Virus, as active ingredient, Paurin, on the antagonist bacteria Pseudomonas fluorescens, Trichodermin and Gliocladin, on fungus genus Trichoderma as active ingredient. The value of approved biological means lies not only in the biological, ecological and economic implications, but also the possibility of their inclusion in conventional and organic farming systems. 9 references, 1 tables.Основная цель исследовании состояло в анализе результатов полученных в результате разработки и тестирования биологических препаратов предназначенных для борьбы с вредными организмами основных сельскохозяйственных растений. Исследования проведены с применением Вируса ядерного полиедроза Helicoverpa armigera Hbn., антагонистических бактерий Pseudomonas fluorescens BKM CP 330 D, микроскопических грибов Trichoderma lignorum штамм M-10 и Trichoderma virens, штамм 3X). Разработаны оригинальные технологические процессы производства и применения 4 биологических препаратов, зарегистрированных для борьбы с вредными организмами основных сельскохозяйственных культур. Ценность зарегистрированных средств сводится не только в высокой биологической, экологической и экономической эффективности, но и в возможности их использования в системах конвенционного и экологического земледелия.
