以14种加工番茄为试材,采用室内毒力测定与田间药剂防效试验,研究了5种药剂对加工番茄细菌性斑点病的防治效果及番茄抗病性。结果表明:30%烯酰·咪鲜胺抑菌效果较好,抑菌率为73.88%;6%春雷霉素、56.7%氢氧化铜、30%烯酰·咪鲜胺和47%春雷王铜毒力相对较强,EC50分别为8.7、9.6、10.4、10.9mg·mL~(-1)。田间药剂防效试验表明,56.7%氢氧化铜、47%春雷王铜和30%烯酰·咪鲜胺对细菌性斑点病的防效均在60.00%以上,其中30%烯酰·咪鲜胺防效较高为69.66%。供试的14种加工番茄品种中,有1个抗病品种、9个耐病品种、4个感病品种。
Fourteen kinds of processed tomato were used as materials to test the control effect of five kinds of agents on the bacterial speckle disease of tomato and the disease resistance of tomato by indoor toxicity test and field agent control experiment. The results showed that the antibacterial effect of 30% enoyl prochloraz was good, the antibacterial rate was 73.88%, 6% kasugamycin, 56.7% copper hydroxide, 30% enoyl prochloraz and 47% Relatively strong virulence, EC50 were 8.7,9.6,10.4,10.9 mg · mL ~ (-1). The field trials of pesticide control tests showed that the control effects of 56.7% copper hydroxide, 47% brassilles and 30% enoyl prochloraz on bacterial speckle disease were over 60.00%, of which 30% enoyl prochloraz High control efficiency of 69.66%. Of the 14 processing tomato varieties tested, there were 1 resistant variety, 9 resistant varieties and 4 susceptible varieties.
