1985年4—6月河南农大喻璋等同志在洛宁县进行了不同农药和喷药次数防治小麦赤霉病的试验结果表明:(1)40％多菌灵胶悬剂和70％甲基托布津可湿性粉剂对小麦赤霉病的防治效果良好。15％或25％粉锈宁防治效果不明显,但对防锈保叶提高千粒重有一定效果;(2)不同喷药次数(1—3次)防治赤霉病效果无显著差异,只要适时,喷药一次即可取得预期效果。
From April to June 1985, Henan Agricultural University Yu Zhang and other comrades carried out different pesticides and spraying times to control wheat scab in Luoning County. The results showed that: (1) 40% carbendazim suspension and 70% Bujin WP can control wheat scab in good effect. The control effect of 15% or 25% triadimefon was insignificant, but it had certain effect on increasing the grain weight of anti-rust leaves. (2) There was no significant difference in the control effect of different spraying times (1-3 times) Once you can get the desired effect.
