摘要
大田试验表明,多菌灵、百菌清和农抗120交替使用对花生叶部病害有明显的防治效果,而不同杀菌剂的组配方式对防治效果影响不大;当多菌灵、百菌清或农抗120单独使用时,多菌灵和百菌清的效果明显好于农抗120;花生病叶率、病情指数和有效叶面积与荚果产量相关极显著,在新药剂试验初期,用上述指标直接评价农药的防效更经济;杀菌剂对土壤中真菌有一定的影响,而对细菌和放线菌影响不明显,因此不会对土壤带来明显的公害。全生育期喷施3次杀菌剂,在花生收获前一个月停止用药,对花生籽仁不会产生明显的污染。
Results from field trials showed that application of Bavistin, Chlorthalonil, and Antimycoin 120 in turns had significant control effect on peanut leaf diseases, but different component of the germicides had little variance on the control effect. When each of the germicide was applied, the control effect of Bavistin and Chlorthalonil are significantly better than Antimycoin 120. Significantly correlations were observed among ratio of peanut leaf disease or disease index or effective leaf area and pod yield. In the beginning of new pesticide experiment, this way that evaluated control effect of pesticide was cheaper than other ways. The germicide influenced certainly on soil fungus. However influence of the germicide on bacteria and actinomyces was not significant. So the germicide could not cause soil significant pollution. It did not cause peanut seed significant pollution that the germicide was used for three times in peanut growth duration and stopped in one month before peanut harvest.
