Advancement of strategies of ecological agriculture it is lost in thought without application of biological preparations occupy a separate place among the other biological means for plant protection One important element in the technological process of insecticide virus production is an elaboration of a new preparation form of the virus insecticides as well as their commercialization. This work contains testing of biological preparation Virin – ABB-3 – for elimination of Hyphantria cunea Drury in laboratory and field conditions. The preparation is based on viruses of nuclear polyhedrosesis and granuoses with cumulative and synergetic action. Presently the investigation are being carried out the elaboration of other virus insecticide for control in the systems of integrated plant protection of different agricultural, ornamental and forest crops.
