Abstract

Chilli (Capsicum annum L.) is an important vegetable cum spice crop commonly used in Indian diet and grown throughout the year in Tamil Nadu. Infestation of invasive South East Asian thrips species (Thripsparvispinus) was reported in chilli growing areas of Andhra Pradesh, Telangana, Karnataka and Tamil Nadu and caused significant damage during Rabi season 2021-22. Survey results on damage potential and leaf curl disease incidence during rabi season in Putlur, Kilambakkam, Pondavakkam and Cherukkanur villages of Tiruvallur district revealed a maximum Percent Leaf curl index (PLI) of 22.08 with a 36.97 % reduction over potential yield at Cherukkanur village. In field trial, insecticide treatment was imposed after 45 DAP in all three locations and the results observed, indicated that Cyantraniliprole 10.26 % OD (T1) and Spinosad 45 % SC (T4) were found to be effective in reducing chilli thrips population in which significant reduction of 31.11 % and 16.11% in population count in T1 and T4 respectively over the treated check T7 (Imidacloprid 17.80 % SL). The leaf curling symptom due to the feeding of thrips was least in T1 followed by T4 and T7. Cooccinellids population was observed maximum of 1.67 per plant in T1 followed by T4 and T7. Hence, diamide insecticide Cyantraniliprole 10.26 % OD significantly reduced the thrips incidence with two sprays followed by Spinosad 45 % SC over the control check Imidacloprid 17.80 % SL.
