This paper presents the ideas of the authors, confirmed by the results of a stationary field experiment on the possibility of widespread use of modern biological products of insecticidal action in the system of protection of the main oilseed crop of the Republic of Tatarstan namely spring rapeseed from such most harmful objects as cruciferous flea, cabbage moth, rape sawfly, flower beetle, secretive proboscis etc. The stationary field experiments were carried out on the basis of the agrarian biological technological park of Kazan State Agrarian University. The laboratory analyzes were carried out at the center of agroecological research of the agronomic faculty. The soils of the experimental site were gray forest, with the following agrochemical indicators: the content of humus according to Tyurin was 3.0%, mobile phosphorus was high (160 mg / kg) and exchangeable potassium was increased (145 mg/kg according to Kirsanov). The objects of research were the crops of spring rape of the Ruyan variety named after V.S. Pustovoyta, biological preparations Nodix Premium, Nodix Insectobact and Nodix Biofungicide. The importance of these studies is explained by the fact that in recent years, the number and resistance of pests of spring rape to chemical insecticides has increased and, accordingly, the chemical load on the environment has also increased. In this regard, the study of promising insecticides of biological origin on spring rape is an urgent task. During the research, it was found that the pre-sowing treatment of seeds with Insectobact (1 l / t of seeds) in combination with a nutrient solution Nodix Premium (0.3 l / t) in terms of the effectiveness of suppressing cruciferous flea bees is equivalent to dressing the seed with a chemical dressing agent Cruiser Rape (15 l / t). t). Moreover, a significant reduction in the chemical load on the environment ensures the use of the same biological products against other pests during the growing season of plants.
