Abstract: [Objective] To understand the effect of pendimethalin,prometryn and two kinds of medicament mixture to processing tomatoes and broomrape seed germination,processing tomato growth.[Method]The seed treatment and pot experiment were used in the study.[Result]Seed treatment test results showed that germination inhibition rate of 33;pendimethalin oil 7 μg/mL,50;prometryn wettable powder 7 μg/mL and two kinds of medicament mixture 1 μg/mL to broomrape seed were high and the tomato seed germination inhibition rate was low;Pot experiment results showed that inhibition effect of 33;pendimethalin oil 10 μg/mL,50;prometryn wettable powder 7 μg/mL and two kinds of medicament mixture 7 μg/mL to broomrape unearthed and growth was remarkable,and there was small or no inhibition to tomato plants growth.[Conclusion]33;pendimethalin oil,50;prometryn wettable powder and two kinds of medicament mixture had the potential to control broomrape in processing tomato field.

摘要： [目的]了解二甲戊灵、扑草净和两种药剂混合物对加工番茄和列当种子萌芽、加工番茄生长的影响.[方法]采用种子处理和盆栽试验.[结果]种子处理试验结果表明,33;二甲戊灵乳油7 μg/mL处理、50;扑草净可湿性粉剂7 μg/mL和两种药剂混合物1 μg/mL对列当种子萌芽抑制率高,且对番茄种子萌芽抑制率低;盆栽试验结果表明,33;二甲戊灵乳油10 μg/mL处理、50;扑草净可湿性粉剂7 μg/mL处理和两种药剂混合物 7 μg/mL处理对列当出土和生长抑制效果显著,且对番茄植株生长抑制作用小或无抑制作用.[结论]33;二甲戊灵乳油、50;扑草净可湿性粉剂及两种药剂混合物具有在加工番茄田间应用防治列当的潜力.
