Сomparative evaluation of different soy protection schemes

Goal. Evaluate the effectiveness of various soybean protection schemes using preventive measures for seedlings and control during growing season.
 Methods. Field, phytopathological, herbological, mathematical statistical. According to first scheme, seeds were treated comprehensively with Maxim XL 035 FS (fludioxonil, 25 g/l + metalaxyl-M, 10 g/l) fungicide, 0.5 l/t, Taboo s.c. (imidacloprid, 500 insecticide, l/t Biomag-Soya (Bradirhizobium japonicum) biological product, village, 2.5 l/t. Harnes c.e. (acetochlor, 900 g/l), herbicide was applied sowing a consumption rate 2.0 l/ha. second scheme season herbicides Bazagran, l.c. (bentazone, 480 l/ha Panther, c.e., 1.0 (quizalofop-P-tefuril, 40 in phase 3—4 true leaves culture. Against diseases budding — beginning flowering at bean formation sprayed fungicide systemic contact action Amistar Extra 280 SC (cyproconazole, 200 azoxystrobin, 80 0.75 The quantitative species composition weeds experimental plots, infestation phytopathogens plants, drugs schemes, crop yield determined.
 Results. Both effectively controlled weed disease. proved be more effective against dicotyledonous weeds: 60 days after application 95.4% versus 82% according scheme. Cereal season. Protection soybeans Alternaria almost equally both schemes. Soybean downy mildew limited fungicidal treatments Under yielded significantly higher yields than controls. However, yields, number beans per plant weight 1000 grains compared scheme.
 Conclusions. provided high disease rates Differences different groups types are obviously related peculiarities use toxic effects used. system can reduce pesticide load on agrocenosis limit negative impact pesticides plants
