摘  要:
丝黑穗病是玉米主要病害之一,采用杀菌剂可有效地防止该病的侵染,控制其为害。为了筛选对丝黑穗病防效好的拌种药剂,2010年对山西省市售的8种药剂进行了田间药效试验。结果表明,8种药剂拌种对玉米出苗基本没有影响,对玉米丝黑穗病防效明显,降低了发病率,相对防效达到50.6%~86.9%,其中,以20%吡.福.戊唑的防治效果最好,丝黑穗病株率最低,为3.1%,相对防治效果为86.9%;其次为戊唑醇,病株率为3.7%,防治效果为84.4%。

摘  要:
Head smut is one of the main diseases in maize,which could be effectively prevented with fungicide to control its damage.To select effective seed dressing pesticide to prevent head smut,the efficacy of the eight market pesticides was studied and evaluated through field experiments.The results showed that the eight seed dressing agents had no influence on corn germination,but had the obvious control effect to reduce the risk of the disease.The relative control effect reached 50.6% ~ 86.9%.The seed dressing of the pyrazole riflumizole and tebuconazole had the best control effect of 20%,head smut diseased plant rate was the lowest 3.1%,and the relative control efficiency was 86.9%.In the second place standed tebuconazole which showed the diseased plant rate 3.7% and the relative control efficiency 84.4%.
