为探讨杀菌剂与哈茨木霉菌互作防治植物病害增效作用的评价方法,河北省农林科学院植物保护研究所近期采用对峙法、孢子悬浮液法和离体叶片法,分别测定了哈茨木霉菌与啶酰菌胺互作对番茄灰霉病菌的抑制作用,用互作系数>1作为互作增效作用的评价标准,并用离体叶片法验证其评价结果。3种方法表明,啶酰菌胺和哈茨木霉菌互作后对番茄灰
In order to investigate the synergistic effect of fungicide and Trichoderma harzianicum on plant disease control, Plant Protection Institute of Hebei Academy of Agriculture and Forestry recently adopted confrontation method, spore suspension method and in vitro leaf method, respectively, to determine the Trichoderma harzianum and The interaction of boscalid against Botrytis cinerea was evaluated by using the interaction coefficient> 1 as the evaluation criterion for the synergism of the interactions and the results of the evaluation by the in vitro leaf method. Three methods showed that boscalid interacted with Trichoderma harzianum against tomato ash
