| dc.description.abstract | Rice is one of the most important staple foods of India including the state of Jharkhand. The crop is usually badly affected by half of a dozen of major insect pests .Use of chemical insecticides is one of the most effective tool of pest management but it’s injudicious usage has too many side effects. So use of eco– friendly and neem based tools of IPM namely HPR, suitable adjustment in dates of planting and use of eco-friendly insecticides is a need of present time for sustainable management of pests without harming the environment and ecosystem. Keeping all these facts in view the present investigation was undertaken. Out of 16 prevailing insect pest species in rice ecosystem, five of them occurred as major pest’s viz. YSB, hispa, leaf folder, GLH and ear bug. The rice varieties viz., Kavya, Suraksha, IR-36, and BG-380-2 remained resistant to the five major insect pests, resulting in higher yield of 38.70, 35.80, 26.70and 42.80 q/ha respectively, even when they were grown in the unprotected condition. TN-1, Pusa Basmati -1, IR-64,Swarna and Birsa mati exhibited susceptibility to the pests resulting in lower yield of 16.38 , 42.50, 38.50,40.50, and 44.50 q/ha respectively . Minimum incidence of major pests namely – YSB, hispa , GLH and gundhi bug was observed when the crop was transplanted at the earliest (i.e. on 1st of July , 15) whereas maximum incidence of gundhi bug was found when the transplantation of the crop was delayed. Highest yield was also found when the crop was transplanted at the earliest. Need based foliar sprays with neem based insecticides applied at 25, 35, 50, 80 and 115 days after transplanting (DAT) proved to be highly effective against prevailing major insect pest. Monocrotophos being the most effective in this regard resulting in the highest yield when compared to 11 neem based insecticides, Achook, Neemark, and NSKE-5% proved more effective in reducing the incidence of the major insect pests. As such, integration of various IPM tools i.e., HPR (i.e. resistant varieties) coupled with early planting of the crop, need based and judicious application of the neem formulations could be highly effective component (tool) as an integral part of IPM/ICM for sustainable rice production. | en_US |
