摘要
以进口杀菌剂爱苗和国内常用杀菌剂多菌灵为对照,研究了大蒜提取液对番茄4种病原真菌的抑制作用。结果表明:爱苗对4种病菌的抑制作用最大,大蒜提取液抑菌作用好于多菌灵。大蒜提取液对炭疽菌的EC90为586倍稀释液,对早疫菌、叶霉菌和灰霉菌的EC90分别为149,173,446倍。大蒜提取液和2种农药对番茄4种病原真菌有很强的抑制作用,但不同药剂有不同的专一性。
The inhibition of garlic extract of 4 pathogens in tomato was studied by using aimiao,the imported fungicide,and carbendazim,the commonly used fungicide at home,as the contrast.The results indicated the controlled ability of aimiao EC is the highest,and the garlic extract EC is close to carbendazim powder,but garlic extract EC is better compared to carbendazim powder by garlic extract EC,carbendazim powder and aimiao EC control the growth of 4 pathogens in tomato.By analyzing the inhibitory rate and calculating the trend of fungicide concentration,the EC95 ofFulvia fulva that aimiao EC controlled turns out to be 5 025-time diluent, and that of other fungi is about 2 220 times;the EC90 of Colletotrichum coccodesthat garlic extract EC controlled is 586-time diluent,and that for Alternaria solani,Fulvia fulva and Botrytis cinerea are 149,173 and 446 times respectively;EC90 of Fulvia fulva that carbendazim powder controlled is 178-time diluent,and that for Alternaria solani,Colletotrichum coccodes and Botrytis cinerea are 111,145,107 times respectively.In a word,garlic extract EC and 2 fungicides have very strong ability in controlling the growth of the 4 pathogens in tomato,and the trend of fungicide concentration is consistent with the measured result,but the specificity is different for different fungicides respectively.
