THE USE OF ENVIRONMENTALLY SAFETY PRODUCTS TO CONTROL BLACK-CURRENT PHYTOPHAGANS IN THE KEMEROVO REGION
The use of biological products in small-fruit (berry) crop growing remains topical primarily because of their environmental safety for plants and beneficial entomofauna. Black-currant (Ribes nigrum L.) is one of the most valuable berry crops grown in Siberia. More than 75 different species of plant eaters feed on black-currant including gooseberry fruit moth (Zophodia convolutella Hbn.), currant big bud mite (Cecidophyes ribis Westw.), currant shoot borer (Lampronia (Incurvaria) capitella Cl.), and some species of aphids, spider mites, scale insects, etc. This study deals with the effect of biological products on the number of black-currant phytophagans in West Siberia. Field experiments were conducted in 2013 and 2014 according to the conventional techniques in black-currant plantations on the farm of the OOO “Plodopitomnik” company situated in the Prokopyevskiy District of the Kemerovo Region. The biological features of currant big bud mite and lepidopterous insect pests were studied: gooseberry fruit moth and currant shoot borer. The black-currant varieties Ksyusha (standard), Rita, Cherniy zhemchug, Agrolesovskaya, Mila and Pushistaya were evaluated for their resistance to phytophagans. The optimal treatment timing and effectiveness of biological products were determined. It was found that the variety Ksusha was damaged by phytophagans to a greater extent than other varieties. The tests of biological products Fitoverm and Lepidocide showed their high biological effectiveness. The biological effectiveness of Lepidocide against lepidopterous insect pests made 59% on the average, and that of Fitoverm made 69.3% at a concentration of 0.4%.
