Experience of using pesticides to control protected soil pests in the CSBG SB RAS (Novosibirsk)

The article presents the results of application of pesticides with different spectrum of action against the main pests of protected soil greenhouse whitefly and thrips in a large greenhouse complex of the Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences. It was found that the efficiency of treatment with the preparations Clipper, KE, Tanrek, VRK, Movento-Energy, KS and Applaud, SP against whitefly was 50-70%, and the insecticide Aktara, VDG against thrips 80%. The use of tank mixtures stably limits the number of phytophages below the EPT. The greatest efficiency against whitefly was shown by triple treatment with tank mixtures consisting of alternating preparations Plenum, VDG, Admiral, KE, Mospilan, RP, Talstar, KE with an interval of 16 days. The inclusion of Verimark, KS in tank mixtures made it possible to obtain 100% efficiency against thrips. To prevent outbreaks of the main greenhouse pests, which, as a rule, require the use of complex tank mixtures consisting of expensive preparations, it is necessary to maintain a system of preventive measures, including a set of measures (agrotechnical, quarantine, etc.) recommended for greenhouse premises. When planning protective measures, it is necessary to take into account the biology of greenhouse whitefly and various types of thrips. Preventive chemical treatment against pests in the autumn, when greenhouses are sealed for the winter, is relevant in Siberian conditions. This will prevent an increase in the number of phytophages in the winter and spring and reduce the number of chemical treatments.
