摘要
为明确常用生物杀菌剂对谷子生长的安全性及对谷瘟病的防治效果,选用3种常用的生物杀菌剂,分别设置低、中、高量,通过田间小区试验,筛选出低毒、低残留、安全、高效的防治谷瘟病的生物杀菌剂。结果表明:1 000亿芽孢·g^(-1)的枯草芽孢杆菌可湿性粉剂及2%春雷霉素水剂对谷瘟病的防治效果明显好于10%多抗霉素水剂,防治效果差异显著。其中1 000亿芽孢·g^(-1)的枯草芽孢杆菌可湿性粉剂有效成分用量1 125、1 500g·hm^(-2),2%春雷霉素水剂有效成分用量30、36g·hm^(-2)处理对谷瘟病的防治效果较好,施药后10d,防治效果在76.42%～82.23%;施药后20d,防治效果在73.05%～78.59%。
In order to clear the safety of common biological fungicides on the growth of millet and the control effect on millet blast,we used three common biological fungicides,were set low,medium and high levels,by the field experiment,screened out low-toxic,low-residue,safe and efficient biological fungicides for controlling millet blast.The results showed that the control effect of 100 billion spores per gram bacillus subtilis WP and 2%Kasugamycin AS were significantly better than 10%Polyoxin AS,control effect significant difference.Among them,the treatment of 100 billion spores per gram bacillus subtilis WP 1 125,1 500 g·hm^-2 and 2%Kasugamycin AS 30,36 g·ha^-1 had better control effect on millet blast,on 10 days after spraying,the control effect was 76.42%-82.23%,on 20 days after spraying,the control effect was 73.05%-78.59%.
