阿坝县云杉落针病防治效果初探

A Preliminary Discussion on the Control Effect of the Needle Cast of Spruce

通过采用百菌清烟剂(15 kg.hm-2)及75%百菌清可湿性粉剂(15 kg.hm-2)对云杉落针病进行防治实验,结果表明:百菌清烟剂和75%百菌清可湿性粉剂防治两次,防治效果均可达到75%以上,防治两次效果明显好于防治一次,75%百菌清可湿性粉剂防治两次效果明显好于百菌清烟剂防治两次。

Control experiments on needle cast of spruce was conducted by applying 75% of daconil solution and daconil fumigant,the result indicated that the use of 75% of daconil solution（600×solution of mildothane） and daconil fumigant 2 times had favorable effect,able to reach above 75%,2 times control was better than 1 time,and 2 times control effect by using 75% of daconil solution was better than that by using the daconil fumigant.
