Elements of the integrated system of protection of sunflower from illnesses in the Tambov area

As elements of the integrated system of protection of sunflower optimum terms of sowing of the given culture and pro-cessing of seeds of tank mixes including a biological product or протравитель, regulators of growth of plants and VDB are con-sidered. Sunflower crops in first two terms of sowing provided reception of the greatest productivity - 2,04-2,09 t/hectares. At average terms of crops (for 10-15 days after early) productivity decreased on 0,15-0,19 t/hectares, and at late (for 20-25 days after early) on 0,29-0,44 t/hectares. Preseeding processing of seeds of sunflower of tank mixes vermicullen LC, 3 l/t + immunocyto-phyt, 0,5 g/t+ WDB, 0,2 l/t has provided biological efficiency in struggle against the radical form of white decay - 73,6 %, with fusariose - 45,9 %, the size of an additional crop made 0,18 t/hectares, on the average for three years of researches.
