摘  要：
[目的]通过田间药剂试验,明确几种杀菌剂对水稻稻瘟病的防治效果.[方法]采用田间喷雾的方法对水稻稻瘟病进行防治.[结果]药后14 d,75%三环唑可湿性粉剂225 g a.i/hm2和25%咪鲜胺乳油270 ga.i/hm2防效分别为65.84%和62.61%,显著高于15%氯啶菌酯·戊唑醇悬浮剂67.5 g a.i/hm2的防效,与15%氯啶菌酯·戊唑醇悬浮剂112.5 g a.i/hm2、15%氯啶菌酯·戊唑醇悬浮剂157.5 g a.i/hm2、30%醚菌酯悬浮剂270 g a.i/hm2的防效无显著性差异.各药剂处理对水稻生长发育无异常影响、无药害.[结论]75%三环唑可湿性粉剂225 g a.i/hm2、25%咪鲜胺乳油270 g a.i/hm2、30%醚菌酯悬浮剂270 g a.i/hm2和15%氯啶菌酯·戊唑醇悬浮剂157.5 g a.i/hm2对水稻稻瘟病的防治效果较好,可在大田合理轮换使用.

Control Effect of Several Fungicides on Rice Blast
摘  要：
[Objective]The purpose of the present study conducted was to screen several fungicides which would have better control effect on rice blast.[Method] Four kinds of fungicides were used by being sprayed to control rice blast at test concentration.[Result]After fourteen days,the result showed that the treatments of 75% tricyclazole WP with the dosage of 225 g a.i/hm2,25% prochloraz EC with the dosage of 270 g a.i/hm2,30% kresoxim-methyl SC with the dosage of 135 g a.i/hm2 and syp-7017·tebuconazole 15% SC with the dosage of 157.5 g a.i/hm2 had better effect on Magnaporthe oryzae,with the control effect of 65.84%,62.61%,59.55% and 58.88%,respectively.All the treatments did not negatively influence the growth and development of the rice.[Conclusion]The control effects of 75% tricyclazole WP with the dosage of 225 g a.i/hm2,25% prochloraz EC with the dosage of 270 g a.i/hm2,30% kresoxim-methyl SC with the dosage of 270 g a.i/hm2 and mixed syp-7017·tebuconazole 15% SC with the dosage of 157.5 g a.i/hm2 were quite effective,so it was suggested that they could be applied alternately in the large area of field.
