Efficiency of seed dressers for sunflower protection against the diseases

Английский. In a course of the research there was studied the efficiency of seed dressers TMTD, ASC, Maxim, SC, Protect, SC, Insur perform, WС, Cruiser rape, SC in defense of sunflower (Helianlhus annuus) from disease. The research was realized in the conditions of the Republic of Belarus in 2013-2014 in laboratory and field experiments of RUE ‘Institute of Plant Protection’ (Priluki, Minsk region) on sod-podzolic soils. As a result of realized research it was revealed that the studied preparations promoted a decrease of seed grain contamination by fungi Alternaria sp., Fusarium sp., as well as the fungus Botrytis cinerea Pers. Seed dressers did not render the negative effect on energy germination and on seed germination. The sunflower seed dressers TMTD, ASC (4.0 l/ha), Maxim, SC (2.0 l/t), Inshur Perform (0.5 l/t), Protect, SC (2.0 l/t) , Cruiser rape, SC (11.0 l/m) ensured of seed infection decrease and development of fungi Alternaria spp., B. cinerea and Fusarium spp. to 22.0-25.0% as compared with the control 52.0 and 40.0% respectively. In field experiments protectants hindered the development of disease to the stage of stem growth in length.

В статье приведены результаты исследований по эффективности протравителей семян ТМТД, ВСК, Максим, КС, Протект, КС, Иншур перформ, КС, Круйзер рапс, СК в защите подсолнечника масличного от болезней. Изучаемые препараты способствовали снижению зараженности посевного материала грибами рода Alternaria, Fusarium, а также гриба Botrytis cinerea Pers. Протравители не оказывали отрицательного действия на энергию прорастания и лабораторную всхожесть семян.
