- 摘要:
- 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、10.9 mg?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。
- Abstract:
- Fourteen processing tomatoes were used as materials，indoor toxicity measurement and filed experiment were carried out，the resistance of 14 processing tomato species to bacterial speck of tomato was evaluated and the fungicides were screened.The results showed that 30% dimethomorph?prochloraz was the most antibacterial with 73.88% bacteriostatic rate,6% kasugamycin，56.7% copper hydroxide，30% dimethomorph+prochloraz and 47% kasugamycin+copperoxychloride had stronger virulence，and their EC50 respectively were 8.7 mg?mL-1，9.6 mg?mL-1，10.4 mg?mL-1，10.9 mg?mL-1.The field control effect test results showed that the control effect of the 56.7% cupric hydroxide，47% kasugamycin+copperoxychloride，and 30% dimethomorph?prochloraz to bacterial speck could be up to 60.00% or more，of which 30% dimethomorph+prochloraz had good control effect of 69.66%.The results of resistance appraisal 14 kinds of processing tomato varieties to bacterial speck showed that there were one disease-resistant variety，nine disease-tolerant varieties，four disease-sentive varieties in the varieties tested,30% dimethomorph?prochloraz had better control effect against bacterial speck of tomato.
