摘要
Abstract
Rice blast is the main rice disease, and chemical control is the most effective measures at present. This study tested the control effects of some rice blast control specific fungicides and broad-spectrum fungicides, discussed the optimal control period of rice blast, the possibility of combination control rice false smut and rice neck blast through the method of field control experiment combi-nation with indor test. The results showed that tricyclazole was still the best fungicide to control rice neck blast. The broad-spectrum fungicides, such as azoxystrobin, trifloxystrobin·tebuconazole and azoxystrobin·difenoconazole, showed better performance in control-ling leaf blast; initial heading stage was the best stage for controlling rice neck blast, it was necessary to give another chemical spray in full heading stage when neck blast very serious. 5~7 days before heading stage was the best stage to control false smut of rice, there was also some effects for controlling rice neck blast. Therefore, it is feasible to control rice neck blast and rice false smut at one time.关键词
