    STUDIES ON SEASONAL INCIDENCE AND BIO-EFFICACY OF INSECTICIDES AGAINST MAJOR INSECT PESTS OF CHILLI (Capsicum annuum L.)
    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2021-12-07) SAINI, LAXMAN SINGH; Meghwal, H. P.
    The present investigation entitled “Studies on Seasonal Incidence and Bio-efficacy of Insecticides against Major Insect Pests of Chilli (Capsicum annuum L.)” was conducted at experimental farm, Agricultural Research Station, Ummedganj- Kota (Rajasthan) during Rabi 2020-21. The infestation of aphid, thrips and whitefly were initiated after 2nd week of transplanting of chilli seedling (44th SMW) and reached it’s peak population as 8.27 aphids/3 leaves, 10.40 thrips/3 leaves and 6.20 whitefly/3 leaves after 7th week of transplanting (49th SMW). The population of mite and fruit borer was appeared after 5th and 13th week of transplanting of chilli seedling (47th and 3rd SMW, respectively) and reached it’s peak (3.47 mite/3 leaves and 4.13 larvae/ plant, respectively) after 17th week of transplanting (7th SMW). Population of aphid, thrips, whitefly, mite and fruit borer in chilli showed negative correlation with maximum temperature and rainfall, while positive correlation with morning relative humidity. All insecticide treatments were found significantly superior in reducing population of major insect pests as compared to control. Combination of insecticides as per spray schedule in treatment T1 (Acetamiprid 20 SP @ 100 g/ha + Ethion 50 EC @ 1500 ml/ha in 1st spray, Imidacloprid 17.8 SL @ 125 ml/ha + Propargite 57 EC @ 1500 ml/ha in 2nd spray, Buprofezin 25 SC @ 300 ml/ha + Fenazaquine 10 EC @ 1250 ml/ha in 3rd spray, Fipronil 5 SC @ 1000 ml/ha + Spiromesifen 240 SC @ 400 ml/ha in 4th spray and Chlorantraniliprole 18.5 SC @ 150 ml/ha in 5th spray was applied) was found significantly most effective against aphid, thrips, whitefly, mite and fruit borer population up to 15 days after treatment with low population as 1.87 aphids/3 leaves, 2.63 thrips/3 leaves, 1.77 whitefly/3 leaves, 0.39 mite/3 leaves and 0.53 larvae/ plant, respectively. Higher yield of green chilli fruit (96.00 q/ha), additional yield over control (41.33 q/ha), avoidable yield loss (43.06 per cent), additional gross return (Rs 103334/ha) and additional net return (Rs 87252/ha) was recorded in treatment T1.
