EFFICIENCY OF SELECTED INSECTICIDES AGAINST GREEN PEACH APHID, Myzus persicae L. AND VIRUS INCIDENCE ON POTATO
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 53
Abstract
Studies were conducted in two locations of Chikkamagaluru district on the efficiency of some insecticides against Myzus persicae L. on potato crop at malnad (Hilly zone) belt of Karnataka during Rabi 2014-15. Results showed that, At Lakshmipura (Location 1), thiamethoxam followed by imidacloprid and acephate were effective in controlling aphid population. PVY incidence was low in thiamethoxam treated plots compared to other insecticide treated plot. However, none of the insecticides were effective in reducing PLRV incidence. At Karkipete (Location 2), imidacloprid, thiamethoxam, acetamiprid and acephate were effective. Pooled data of both the locations indicated, thiamethoxam and imidacloprid were superior in controlling aphid population. The implication of the study in seed potato production is discussed.
