| 摘 要： | 选用甲霜灵等6种杀菌剂对番茄苗期猝倒病及其致病菌-辣椒疫霉菌进行了盆栽防治试验和毒力测定。用辣椒疫霉菌进行活体接种筛选的结果表明,在安全使用浓度下,10%霉灵乳油、10%稻瘟灵乳油防治效果较好。毒力测定结果表明,各药剂对辣椒疫霉菌的毒力高低依次是:甲霜灵>代森锰锌>霉灵>稻瘟灵>霜霉威>异菌脲。

| Abstract: | Six fungicides were selected for controlling the damping-off of tomato seedling. At the case of inoculation with Phytophthora capsici Leonian, the effects of hymexazol 10EC and isoprothiolane 10EC were higher than the others on the safe concentration to seedlings. The toxicities of six fungicides to Phytophthora capsici Leonian were also tested. The results showed that the sequence of toxicity to this pathogen was metalaxyl﹥mancozeb﹥hymexazol﹥isoprothiolane ﹥propomocarb﹥iprodione. |
