abstract
A field experiment was conducted to test the efficacy of treatments for the control of white tip nematode (Aphelenchoides besseyi) in rice during 2015. Results showed that administration of treatments in rice cultivation significantly reduced white tip disease symptoms and nematode population in rice grain. The seed treatment with monocrotophos 36 SL @ 0.075% before sowing was found to the most effective for reduction of foliar distortion and increase of yield for the control of nematode. The foliar spray of monocrotophos 36 SL @ 0.075% at 20 DAS (days after sowing) and 50 DAS at boot leaf stage reduced nematode infestation. The seed treatment with carbosulfan 25 EC @ 0.075%, and hot-water at 52-53ËšC water for 10 minutes effectively controlled nematode and enhanced rice yield. The present study demonstrated that all the treatments are effective to control the nematode and the rice grower can adopt any treatments depending upon suitability and resources conditions.
