Abstract:

Among all the treatments Spinosad 45 SC @ 0.3 ml/l  has recorded least mean progeny adults of 22.33 and 15.00 during 2017-18 & 2018-19, respectively when compared to 591.67 and 507.67 mean progeny adults in untreated control and the treatment differences are significant with each other at 180 days after storage (DAS). Similarly, Malathion 50 EC @ 2.0 ml/l has recorded second least mean progeny adults of 89.67 and 54.67 during 2017-18 & 2018-19, respectively and the treatment differences are significant between Spinosad and Malathion pre harvest spray. The remaining chemical insecticides i.e. Chlorpyriphos 20 EC 2.5 ml/l, Dichlorovas 76 EC @ 2.0 ml/l, Cypermethrin 10 EC @ 1.0 ml/l has recorded high progeny build up when compared to Spinosad and Malathion and proved ineffective in reducing progeny buildup of Sitotroga in storage. The germination per cent in untreated control, Neem oil @ 0.5% and NSKE @ 5% is reduced gradually due to Sitotroga damage and reached to 81.3 %, 83.0 % and 84.7 % (2017-18) & 83.7 %, 85.3 % and 85.7 % (2018-19), respectively at 180 DAS,  whereas the germination is retained in treatments Spinosad 45 SC @0.3 ml/l and Malathion 50 EC @ 2 ml/l at 90.7 % and 90.0 % (2017-18) & 91.0 % and 90.3 % (2018-19), respectively, due to least damage by Sitotroga at 180 DAS.  Spinosad 45 SC @ 0.3 ml/l has recorded least number of total progeny adults of 46.33 (2017-18) and 29.33 (2018-19) in 180 days storage and it is most effective treatment in reducing progeny build up of Sitotroga. The next best treatment is Malathion 50 EC @ 2.0 ml/l which recorded total progeny adults of 212.00 (2017-18) and 175.67 (2018-19) in 180 days of storage under ambient conditions.
