STUDYING THE BIOLOGICAL EFFICACY OF INSECTICIDES TO PROTECT THE SEEDLINGS OF RAPESEED
Abstract
One of the main aspects of rapeseed cultivation is the protection of seedlings from early – onset pests, in particular from cruciferous fleas. Researches about study the biological effectiveness of various insecticides to protect seedling canola were conducted on the experimental plot of the laboratory of plant protection, RGAU – ICCA named after KA Timiryazev in the 2008 – 2009 and 2011 – 2012. The data on the economic evaluation of various ways to protect spring rape from cruciferous fleas are presented. Pre – sowing seed treatment with insecticidal disinfectants is an effective measure for the protection of rapeseed against early – occurring pests. It is also necessary to take into account the environmental safety of this protection measure by preserving the useful entomofauna, including pollinators, reducing the load on the soil, eliminating at least one ground treatment with insecticides, as well as reducing the amount of pesticide applied per 1 ha of field. In addition, the use of such a protection measure as pre – sowing treatment instead of spraying seedlings with insecticides reduces the seasonal load on the machine and tractor fleet.
