ThesisItem Open Access Insect-Pests of Soybean [Glycine max (L.) Merrill] and Their Management(COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2020-09-10) PARMAR, DEVESH; Chaudhary, H. R.The present investigation on “Insect-Pests of Soybean [Glycine max (L.) Merrill] and Their Management” was conducted during kharif, 2019 at Agricultural Research Station, Ummedganj, Kota. The results revealed that among the sap feeding insects whitefly and jassid were reported on the crop almost all cropping period. Maximum infestation of whitefly (7.8/3 trifoliate leaf) observed in first week of September, whereas maximum number of jassid (2.8/3 trifoliate leaf) was recorded in third week of September. In case of relative efficacy, two spray application of Thiacloprid 21.7 SC @ 750 ml/ha was found most effective in reducing the nymph and adult of both the observed insect pests. Among the defoliators viz., tobacco caterpillar (2.4 larvae/mrl), green semilooper (3.2 larvae/mrl), gram pod borer (1.4 larvae/mrl), red hairy caterpillar (2.0 larvae/mrl), bihar hairy caterpillar (2.4 larvae/mrl) and grasshopper (2.4 nymph and adult/mrl) observed predominately on crop varying different crop stages. Chlorantraniliprole 18.5 SC @ 150 ml/ha was found most effective among the various insecticides against these dreaded insect pests on crop in all the stipulated period. In case of borers, girdle beetle has been observed predominant insect pest and its infestation increases as the crop stages up to 26.20 per cent. Application of Chlorantraniliprole 18.5 SC @ 150 ml/ha prevented increasing infestation up to 12.24 per cent. The maximum seed yield, additional yield, avoidable yield loss and additional returns over control was also obtained from the plots treated with Chlorantraniliprole 18.5 SC @ 150 ml/haThesisItem Open Access Studies on Population Dynamics and Management of Defoliator Insect-Pests on Soybean [Glycine max (L.) Merrill] in South-Eastern Rajasthan(COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2020-09-04) YADAV, VIJENDRA; Meghwal, H. P.The present investigation entitled “Studies on Population Dynamics and Management of Defoliator Insect–Pests on Soybean [Glycine max (L.) Merrill] in South-Eastern Rajasthan” was conducted at experimental farm, Agricultural Research Station, Ummedganj, Kota (Rajasthan) during kharif 2019. Population dynamics of defoliator insect-pests on five promising varieties of soybean (RKS-24, RKS-45, RKS-113, JS-335 and JS 97-52) revealed that none of the variety was found free from infestation of defoliators, however larval infestation trend was observed in this order JS-335 > JS 97-52 > RKS-113 > RKS-24 > RKS-45. The peak larval population was foundin all the varieties evaluated as green semilooper and bihar hairy caterpillar during 34th SMW, pod borer during 36th SMW and tobacco caterpillar during 38th SMW. All treatments were found significantly superior in reducing the larval population of defoliators viz., tobacco caterpillar, green semilooper, pod borer and bihar hairy caterpillar as compared to control. The treatment of Chlorantraniliprole 18.5 SC @ 150 ml/ha was found most effective with minimum larval population of defoliators followed by Indoxacarb 14.5 SC @ 333 ml/ha. Higher seed yield of soybean (1952.4 kg/ha) was recorded in the treatment of Chlorantraniliprole 18.5 SC @ 150 ml/ha followed by Indoxacarb 14.5 SC @ 333 ml/ha (1904.8 kg/ha) and Triazophos 40 EC @ 800 ml/ha (1873.0 kg/ha). Maximum additional yield over control (492.1 kg/ha), avoidable yield loss (25.20 per cent) and net return (Rs. 14814.6/ha) was recorded in the treatment of Chlorantraniliprole 18.5 SC @ 150 ml/ha. It is concluded that the treatment of Chlorantraniliprole 18.5 SC @ 150 ml/ha was found most effective against defoliators and next best were Indoxacarb 14.5 SC @ 333 ml/ha and Triazophos 40 EC @ 800 ml/ha.ThesisItem Open Access 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.ThesisItem Open Access SEASONAL INCIDENCE AND MANAGEMENT OF MAJOR INSECT-PESTS OF CABBAGE (Brassica oleracea var. capitata L.)(COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2021-12-07) KUMARI, NEHA; Patidar, B. K.“Seasonal Incidence and Management of Major Insect-Pests of Cabbage (Brassica oleracea var. capitata L.)” was conducted at experimental farm, College of Agriculture, Ummedganj-Kota (Raj.) during Rabi-2020-21. The aphid population was observed throughout the crop growth stage period commenced in the first week of December (49th SMW) thereafter, gradually increased and reached to peak in the last week of January (4th SMW). The infestation of diamondback moth was noticed in the last week of November (47th SMW) which gradually increased and reached to peak in the first week of January (1st SMW). The larval population of green semilooper larval population first appeared in the second week of December (50th SMW) which gradually increased and touched to peak in the third week of January (3rd SMW). While, tobacco caterpillar first appeared in the last week of November (47th SMW) which gradually increased and touched to peak in the last week of December (52th SMW). Azadirachtin and Verticillium lecanii were proved to be most effective bio-pesticides against aphid on cabbage, Bacillus thuringiensis (kurstaki) was least effective against aphid. For management of lepidopteran insect-pests on cabbage such as diamondback moth, green semilooper and tobacco caterpillar the most effective chemical pesticides such as Spinosad, Emamectin benzoate and bio-pesticides were Bacillus thuringiensis (kurstaki), Beauveria bassiana found effective. Among the natural enemies, lady bird beetle and predatory spider were commonly observed. The treatment of Azadirachtin was proved safe for lady bird beetles and predatory spiders. Based on yield performance, significantly highest yield was registered in the treatment Spinosad which was at par with treatments Emamectin benzoate, While, the maximum benefit cost ratio (18.59) was recorded in the plots treated with Emamectin benzoate followed by Beauveria bassiana (7.99). The minimum benefit cost ratio (0.17) was recorded in the treatment of Spinosad due to their higher cost during present investigation.ThesisItem Open Access STUDIES ON POPULATION DYNAMICS AND MANAGEMENT OF MAJOR INSECT-PESTS OF BLACK GRAM [Vigna mungo (L.)
