METHOD OF BIOLOGICAL PROTECTION OF SPRING RAPE FROM INSECT PESTS USING THE REPELLENT EFFECT OF PLANTS IN MIXED AND BINARY CROPS

The aim of the study was to investigate the effectiveness of repellent plants as a means of protecting rape in biologized agriculture in the conditions of Kuzbass. Research methods: the studies were conducted in 2024 on the agricultural lands of Azot-Agro LLC. The arable land is located in the Kemerovo municipal district, near the settlement of Zvezdny. Spring rape (variety SibNIIK 32), anise, dill, and wormwood were used as objects of research. The field experiment was developed and laid out according to the methodology of B.A. Dospekhov. The experimental design included: rape (control); rape + anise; rape + dill; rape + wormwood. In options 2, 3, 4, rape was sown in a mixture with repellent plants, in options 5, 6, 7, the plants were sown between the rows of rape (in the second row). Accordingly, options 1 and 8 are controls for each sowing method. Research results: it was found that at the end of the spring rape vegetation, i.e. by the time of pod formation, the pest infestation such as rape blossom beetle, rape sawfly, cabbage moth and cruciferous flea beetle for all four main insect pests significantly decreased and the BE on average for the options (mixed sowing) were 30.5, 45.0 and 54.5%, and for binary sowing 58.9, 61.9 and 69.8%, respectively. Conclusion: the change in the dynamics of insect pests can be explained by the fact that by the period of pod formation, essential oil plants reached the peak of their development, increased their biomass and the maximum concentration of essential oils was present in the air, which could not help but scare away insect pests.
