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。
Field experiments showed that the carbendazim, chlorothalonil and Nongkang 120 were used interchangeably on peanut leaf disease has obvious control effect, but different combinations of fungicides have little effect on the control effect; when carbendazim, chlorothalonil Or agar 120, carbendazim and chlorothalonil were significantly better than agar 120. The leaf rate, disease index and effective leaf area of peanut were significantly correlated with pod yield. In the early stage of new drug test, Indicators direct evaluation of pesticide control more economical; fungicides on the soil fungi have a certain impact, but not obvious on bacteria and actinomycetes, it will not cause significant pollution to the soil. Spraying 3 times during the whole growth period bactericide, stopping the medication one month before the peanut harvest, the peanut kernel will not produce significant pollution.
