摘要
为了明确福美双与啶菌恶唑复配对灰葡萄孢Botrytis cinerea的协同抑制作用,首先采用菌丝生长速率法对保定与承德不同地区的灰霉菌株进行复配试验,筛选出福美双与啶菌恶唑的最佳增效组合5:1。同时测定了福美双与啶菌恶唑的最佳增效组合5:1对孢子和菌核的抑制活性以及对菌丝内容物含量的影响。结果显示,其5:1组合与对照、单剂进行比较,其5:1组合对孢子萌发、菌核的产生和萌发和可溶性糖、可溶性蛋白含量具有显著抑制作用。利用离体叶片法对灰葡萄孢活性进行检测,5:1组合处理在病斑直径、发病率、产孢量和孢子萌发率方面较对照、单剂差异显著,其抑制作用最大。综上所述,福美双与啶菌恶唑复配对灰葡萄孢活性具有协同增效抑制作用。
A synergistic combination of thiram and SYP-Z048 （5：1） has been selected using the mycelial growth rate tests on the Botrytis cinerea strains from different regions of Baoding and Chengde. The effects of the combination of thiram and SYP-Z048 on the spore germination rate, the inhibitory activity of sclerotia, and the contents of the mycelium content has also been studied. The 5：1 combination showed significant inhibitory effects on the spore germination, emergence and germination of sclerotia and soluble sugar, soluble protein content is significant, in contrast with the control and the compound used alone. The inhibitory effects of 5：1 combination on lesion diameters, infection rates and spore germination rates was significantly better than that in control and single compound used alone. To sum up, the combination of thiram and SYP-Z048 has a synergistic inhibitory activity on Botrytis cinerea.
