Protective activities (including chemical ones) remain an integral part of crop production technologies. Assortment of chemicals is being changed all the time. Currently as a part of crop flies management it is permitted to use chemicals belonging to different structural classes. Major advantage, as can be seen in instance of pyrethroids, is the high initial effectiveness (95-100 %) and relatively low price, however its protective period is short. Introduction of seed dressing insecticides into the Russian market was a breakthrough in the insect pest management of crop flies and some other crop insect pests. Bayer CropScience AG developed and registered on the Russian market a first ever insecticide-fungicide seed dressing, Scenic Combi, CS (250+37.5+37.5+5 g/l) which contains 4 active substances (clothianidin, fluoxastrobin, prothioconazole, tebuconazole). This paper presents the data on the effectiveness of modern insecticides in crop flies management in the conditions of Omsk Oblast and Rostov Oblast for a period from 2011 to 2017. Sufficient biological effectiveness (80-100 %) of the wheat insect pest management is established when vegetative plants were sprayed with the following chemicals: Kungfu Super, Eforiya, BOREJ Neo, Thiacloprid + deltamethrin, Chlorpyrifos + cypermethrin, Shaman, Imidacloprid + alpha-cypermethrin, Imidor, Chlorpyrifos, Sharpej, Thiacloprid + lambda-cyhalothrin. The conclusion is made about the applicability of these chemicals providing its inclusion into the State catalogue of pesticides and agricultural chemicals. |
