- 摘要:
- 为筛选出防治水稻稻瘟病的有效药剂，控制和减少稻瘟病对水稻的危害。2017年对3种药剂32.5%苯甲?嘧菌酯悬浮剂、40%稻瘟灵EC和75%三环唑WP进行田间药效试验。结果表明:32.5%苯甲?嘧菌酯悬浮剂防治水稻稻瘟病的平均防效达到79.83%，防治效果显著，可作为大田中用于防治水稻稻瘟病的药剂。
- Abstract:
- In order to screen out effective agents for controlling rice blast,control and reduce the damage of rice blast to rice,in 2017,field efficacy tests were carried out on three kinds of pesticides induding 32.5% benzopyrazole suspension,40% indigo EC and 75% tricyclazole WP.The results showed that the control effect of 32.5% benzoyl azoxystrobin suspension on rice blast was 80.37%,79.93% and 79.19%,and the average control effect was 79.83%.The control effect was significant,which could be used as a field control for rice blast.
