Study on the Control Pesticides and Optimum Period for Rice False Smut of Japonica Rice in South China
摘要
Abstract
Field trial was carried out to screening pesticides of controlling rice false smut(RFS)(Ustilaginoidea virens)which was in-creasingly serious in japonica rice. The results showed that the control effects of Trifloxystrobin-Tebuconazole, Amur, Jingangmy-cin A and Hexaconazole were similar,but significantly higher than the control effects of Difenoconazole-Azoxystrobin,Jingangmy coin and Tebuconazole. Compared with the control, the yields of the 4 pesticides treatments were increased by 4.38%~7.89% respectively. The control effect of application pesticide 1 time each at 10 days before rupturing, 3 days before rupturing and after heading was signifi-cantly better than that of 1 time each before rupturing and after heading, and once after heading. There was significant difference in yield among the 3 treatments.The control effect of application pesticide 1 time each before rupturing and after heading was similar to application pesticide once after heading,but the difference of yield was not significant.关键词
