Вплив агроприйомів і протруювання насіння ярого ячменю на пошкодження внутрішньостебловими шкідниками

Abstract

Influence of organic-mineral fertilizers, soil cultivation technique and chemical treatment of spring barley seeds by the preparation mixture of Dividend Star + Cruiser (1,5 + 0,5 l/t) on damage of tillers by intra-stem pests has been shown. Those procedures were not effective in case of frit fly larvae. A complex effect of seed chemical treatment and organic-mineral fertilizers reduced stem damage by stem flea larvae in 5.2 times, a biological effectiveness was 80.8 %. Seed treatment by the mixture of Dividend Star + Cruiser under soil chisel tillage in comparison with the variant when no treatment was used at the time of tillage, reduced barley sprout damage by stem flea larvae in 10 times, biological effectiveness — 90.0 %.
