苯醚菌酯·戊唑醇防治白粉病生物活性

苯醚菌酯(ZJ0712)·戊唑醇复配而成的新型杀菌剂,经室内生物活性测定结果表明苯醚菌酯·戊唑醇以1:10混配时,该组合物对小麦白粉病、黄瓜白粉病和草莓白粉病均具有很高的杀菌活性.模拟田间药效试验结果表明组合物在10～40 mg/L的处理剂量下,对黄瓜白粉病的防效也在98.40%～71.5%之间.苯醚菌酯·戊唑醇的作用机制虽然不同,但2种有效成分组合在一起,对白粉病具有明显的增效作用,并还能有效延缓抗性的产生.

Bioactivity of "ZJ0712 and Tebuconazole" on the Control of Powder Mildew

Among a novel fungicide mixtures screened in vivo to powder mildew,the results showed the mixture took high bioactivity when the proportion of ZJ0712 and tebuconazole was 1:10.The tests in the field also indicated that the above mixture was perfect on the control of powder mildew.The effect of the mixture was 98.4 to 71.5% against powdery mildew of cucumber at 10-40 mg/l.The results showed that the mixtures in 1:10 had obvious synergistic interaction,and it can postpone fungicide resistance.
