南方水稻黑条矮缩病防控试验

    Control efficacy on south rice black-streaked dwarf disease

    • 摘要: 2013年开展不同措施防控白背飞虱及其南方水稻黑条矮缩病效果试验,结果表明:秧苗期覆盖防虫网对白背飞虱及南方水稻黑条矮缩病的防效达100.00%;大田期以秧田期土壤处理+药剂拌种+移栽前施药(毒氟磷+烯啶虫胺)和大田期施药(毒氟磷+烯啶虫胺)的防控措施较好,该防控措施对白背飞虱的防效达92.75%,对南方水稻黑条矮缩病的防效为80.69%,水稻每667 m2产量526.70 kg。

       

      Abstract: A trial of control efficacy of different control measures on south rice white-backed plant hopper and black-streaked dwarf disease was conducted in 2013. The results showed that the control efficacy on south rice white-backed plant hopper and black-streaked dwarf disease reached 100.00% when covering fly net in seedling stage. In field period, when treated by soil treatment in seedling field+seeding dressing+applying pesticides (toxic fluoride and nitenpyram) before transplantation and applying pesticides (toxic fluoride and nitenpyram) in field period, the control efficacy peaked with 92.75% on white-backed plant hopper and 80.69% on rice black-streaked dwarf disease, and the rice yield was 526.70 kg per 667 m2.
