Abstract

As agrochemicals in agriculture are posing vast problems like environmental pollution, pesticide resistance, pest resurgence, toxicity hazards, secondary pest out breaks, residues in feeds, food, soil and water, and destruction of biodiversity of natural enemies. With a view these demerits, now-a-days further emphasis is being laid on IPM by means of botanicals. Botanicals have long been touted as an attractive choice to man-made chemical insecticides for pest management. Considering the importance of ecofriendly approaches to manage pests, the experiment was designed to determine relative efficacy of different botanical extracts against predatory spider population. So the study was conducted to determine the comparative bio-efficacy of five botanicals, each with three concentrations and untreated control (check) against predatory spider population on rice at MRCFC Khudwani Anantnag during Kharif 2019. The spider population was counted before application of botanicals and one, three, seven and fifteen days after botanical application. The mean live spider population per 10 hills ranged from 5.33-6.67 before treatment of botanicals and 3.33-6.00, 3.67-5.67, 3.67-6.00, 3.33-6.33 and 4.00-6.00 after treatment of botanicals, and that reduction in spider population was 11.66, 16.07 and 19.19%; 16.07, 18.05 and 22.13%; 13.09, 17.49 and 21.02%; 12.29, 15.03 and 16.66%; 17.20, 20.47 and 24.60%; at 1.0, 2.0, and 3.0 ml/ L of water in comparison to check (8.01%), respectively. The trend of reduction of spider’s population decreased with time from one to fifteen days.

Conclusion

The present field investigation was to build up an ecofriendly management of insect pests of rice under irrigated conditions with the help of botanicals, viz., neemazal, eucalyptus oil, camphor oil, lemongrass oil and cedar wood oil at different concentrations. The effect of botanicals on predatory population of spiders revealed that all the treatments were superior to the control for the reduction in spider population in rice. Hence, botanicals can be used in reduction of spider in rice without causing adverse effects on natural enemies and environment in Kashmir.
