不同措施全程防控南方水稻黑条矮缩病效果试验
Control efficacy of different measures in the whole course on rice black-streaked dwarf disease in south China
摘要
Abstract
Trials of control efficacy for the rice black-streaked dwarf disease in south China were conducted in Shunchang County with different control measures in the whole course in 2014. The results showed that the best control efficacy was re-ceived when controlled by covering 30 mesh fly net in rice seedling stage and spraying 60 g 30% Dufulin WP and 24 g 25%Pymetrozine WP per 667 m2 three days before transplanting and ten days after transplanting. The control efficacy ratio reached 90. 48%,and the rice yield was increased by 25. 75%,which indicated that the control measure in the whole course for rice black-streaked dwarf disease could be widely popularized and applicated.关键词
