| 摘 要： | 采用菌丝生长速率抑制法测定了6种杀菌剂对番茄早疫病的抑菌作用,并得到了6个毒力回归方程及抑制有效中浓度(EC<,50>).结果表明,6种杀菌剂对番茄早疫病病原菌的生长均有抑制作用,但不同药剂之间有差异,对番茄早疫病病原菌的EEC<,50>由低到高依次为25%金力士乳油、25%巨佳乳油、10%世高水分散粒剂、70%纳米欣... |

| Abstract: | In this paper,the inhibition of tomato early blight 6 fungicides was determined by using mycelial growth inhibition rate way,and received six regression equations and the inhibition of virulence effective concentration(EC50) are obtained.The results showed that 6 fungicides on tomato early blight inhibit the growth of pathogenic bacteria,but there are differences between the different agents of tomato early blight pathogen EC50 from low to high were 25% Jinlishi EC,25% Jujia EC,10% Shigao WG,70% Namixin WP,... |
