摘要:
为筛选出有效的冬小麦雪腐病菌杀菌剂以指导小麦生产，以冬小麦感病材料337为试材，采用13种杀菌剂对冬小麦雪腐病菌的毒力进行研究。结果表明：13种药剂在系列浓度下对冬小麦雪腐病菌菌丝的生长及孢子的萌发均有不同程度的抑制作用，并对该病害具有一定的防治效果。50%腐霉利WP对冬小麦雪腐病菌的防治效果最佳，其EC50为2.88 mg.L1，菌丝抑制率达到85.48%，孢子萌发抑制率为65.4%，相对防效高达95.7%；12.5%腈菌唑EC的防治效果次之，EC50为4.62 mg.L1，孢子萌发抑制率为66.5%，相对防效为87.1%；50%多菌灵WP效果最差。
Abstract:
n order to screen the effective fungicides for winter wheat to guide its production,taking infected winter wheat 337 as material,the toxicity of 13 kinds of fungicides to Gerlachia nivalis was studied.The results indicated that 13 kinds of fungicides had different inhibitory effect on the mycelium growth and spore germination of Gerlachia nivalis under the tested concentration,and had control efficiency on the disease.50% procymidone wattable powder(WP) showed the best effect and its effective concentration(EC50)was 2.88 mg?L1,hyphae inhibition rate and spore germination inhibition rate were 85.5% and 65.4% respectively,the relative control efficiency was as high as 95.7%.The following was 12.5% myclobutanil EC with EC50 of 4.62 mg?L1,spore germination inhibition rate was 66.5% and the relative control eficiency was 87.1%.50% carbendazim WP showed the lowest inhibition effect to Gerlachia nivalis.
