摘要: 生物农药具有安全高效的特点,与化学药剂混用可以实现化学药剂减量以及防效增加。本文筛选出武夷菌素与嘧菌环胺的增效复配组合,并测定了最佳复配条件下对灰霉病菌菌丝生长发育及分生孢子萌发的影响,评价了葡萄灰霉菌离体叶片的防治效果。结果表明武夷菌素与嘧菌环胺配比体积为9:1时增效作用最显著,毒性比为1.678。复配增效组合导致灰霉菌菌丝不规则膨大、扭曲,显著抑制菌丝生长和分生孢子萌发。增效组合对在离体叶片和果实上的葡萄灰霉病防治效果达75.19%和66.67%,与单剂相比防效分别增加了16.53%~26.35%和19.05%~30.16%。本研究为武夷菌素与嘧菌环胺复配提高葡萄灰霉病的防效提供了理论依据,也为葡萄灰霉病的高效、绿色的防控提供技术指导。

Abstract: Biological pesticides have been demonstrated to be both safe and highly effective. The combination of these biopesticides with chemical pesticides allow for a reduction in the application dosage of chemicals while simultaneously increasing control efficacy. In this study, the synergistic combination of wuyiencin and cyprodinil was screened out. The effects on mycelial growth and conidial germination of Botrytis cinerea under optimal combination conditions were determined. Additionally, the efficacy of this combination in controlling Botrytis cinerea on detached leaves of grape was evaluated. The results showed that the synergistic effect was the most significant when the ratio of wuyiencin to cyprodinil was 9:1, and the toxocity ratio was 1.678. The combination caused hyphae expanded irregularly and grew abnormally, significantly inhibited mycelial growth, and impeded conidial germination of Botrytis cinerea. The control efficacy on detached grape leaves and fruits was 75.19% and 66.67%, respectively, exhibiting a significant increase of 16.53%-27.06% and 19.05%-30.16% compared to the single treatment. This study provides a theoretical basis for the enhanced control efficacy of Botrytis cinerea through the combination of wuyiencin and cyprodinil. It also offers technical guidance for the environmentally friendly and efficient management strategies.

Key words: Botrytis cinerea, wuyiencin, cyprodinil, compound combination, control efficiency
