为筛选防治葡萄灰霉病的高效低毒新型植物源复配杀菌剂,降低有效用药量,提高防治效果,减少和替换对葡萄灰霉病菌产生抗药性的一些常用化学杀菌剂,江苏丘陵地区镇江农科所研究人员采用菌丝生长速率法测定植物源农药丁子香酚、苦参碱及其混配制剂对葡萄灰霉病菌的毒力,并通过田间试验评价其对葡萄灰霉病的防治效果。
In order to screen high-effective and low-toxicity plant-source fungicides against grape gray mold, reduce the effective dosage, improve the control effect and reduce and replace some commonly used chemical fungicides against Botrytis cinerea, Zhenjiang Agronomy researchers using mycelial growth rate method for the determination of botanical pesticides eugenol, matrine and their mixed formulations of Botrytis cinerea virulence, and through field trials to evaluate the prevention and treatment of grape gray mold disease .
