Study on Inhibition of Two Kinds of Herbicide for Processing Tomato and Broomrape Seed Germination and Control Effect

Objective To understand the effect of pendimethalin,prometryn and two kinds of medicament mixture to processing tomatoes and broomrape seed germination,processing tomato growth.MethodThe seed treatment and pot experiment were used in the study.ResultSeed 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.Conclusion33;pendimethalin oil,50;prometryn wettable powder and two kinds of medicament mixture had the potential to control broomrape in processing tomato field.
