摘 要：
采用交叉滤纸条法,对橡胶炭疽病和棒孢霉叶斑病菌进行杀菌剂混用联合毒力研究。结果表明,9种杀菌剂共14个不同的混用组合中,大多数混用表现为相加作用;嘧菌酯和百菌清、抑霉唑和百菌清、溴菌腈和百菌清、腈菌唑与代森锰锌4个组合表现增效作用;而抑霉唑和代森锰锌的混用则表现出明显的拮抗作用。根据对抑菌带的分析,咪鲜胺对两种病菌的抑菌效果均为最高,其次是腈菌唑、抑霉唑和溴菌腈。

摘 要：
The joint action of mixture fungicides on Colletotrichum gloeosporioides Penz. Sace and Corynespora cassiicola (Berk and Curt.) of rubber trees were tested using cross filter paper strip method. The results showed that among 14 combination of 9 kinds of fungicides, most mixture fungicides had additive effect. The commixture of azoxystrobin and chlorothalonil, imazalil and chlorothalonil, bromothalonil and chlorothalonil, myclobutanil and mancozeb had synergistic effect. The commixture of imazalil and mancozeb had significantly antagonistic effect. The inhibition zone analysis found that prochloraz was the most effective against two pathogens, followed by myclobutanil, imazalil and bromothalonil.
