Effects of various new fungicides on damage control and economic traits of rice
Sheath blight is one of the common diseases of rice,and in order to explore the effects of various new fungicides on the damage control effect and economic traits of the main rice varieties in Ningbo,relevant experiments were carried out in Yinzhou,Ningbo.The results showed that tebuconazole,pyroxypropiconazole and benzoxystrobin had better damage control effects on late rice,and had a significant positive impact on economic traits such as grain number per panicle,seed setting rate and yield compared with other treatments.The performance of the new fungicides in early rice was general,and there was no significant difference among the new fungicides and other agents.Early rice sheath blight control can be based on actual needs,and the combination of thiofuramide and other fungicides can be selected.
