摘要：

筛选防治瓜类白粉病的高效药剂，明确吡唑萘菌胺及混剂对苦瓜、西葫芦、甜瓜、西瓜白粉病的田间防治效果，为瓜类白粉病的绿色防控提供科学用药方案。参考田间药效试验准则GB/T 17980.30—2000进行连续3年田间药效试验。11.2%吡唑萘菌胺EC 67.2 g(a.i.)/hm²（制剂600 mL/hm²）、29%吡唑萘菌胺∙嘧菌酯SC 87~261 g(a.i.)/hm²（制剂300~900 mL/hm²）在白粉病初发时兑水675 L/hm²喷雾施药，根据不同作物及病害发展情况，连续施用2~4次，施药间隔期7~14天，防效可达80%以上，持效期可达10~14天，显著高于对照药剂30%醚菌酯∙啶酰菌胺SC、10%苯醚甲环唑 WG、25%三唑酮WP或12.5%腈菌唑 EC的常规用量。11.2%吡唑萘菌胺EC和29%吡唑萘菌胺∙嘧菌酯SC对苦瓜、西葫芦、甜瓜、西瓜白粉病具有良好的防治效果，安全高效，增产效果明显，值得进一步研发登记和推广使用。

Abstract:

To screen effective fungicides to control powdery mildew of cucurbit crops, clarify the field control efficiency of isopyrazam and its mixture on powdery mildew of balsam pear, zucchini, melon and watermelon, and provide a scientific scheme for the green control of powdery mildew of cucurbit crops, some field control efficacy trials were carried out for three years according to the guidelines of field efficacy test GB/T 17980.30—2000. According to the development of different crops and diseases, by 2-4 times applications with 7-14 days intervals and spraying at the initial stage of powdery mildew, the control efficiency of isopyrazam 11.2% EC 67.2 g(a.i.)/hm² (preparation 600 mL/hm²) and isopyrazam· azoxystrobin 29% SC 87-261 g(a.i.)/hm² (preparation 300-900 mL/hm²) were more than 80%. The duration was 10-14 days, significantly higher than that of the conventional dosage of azoxystrobin· boscalid 30% SC, difenoconazole 10% WG, triadimefon 25% WP or myclobutanil 12.5% EC. Therefore, isopyrazam 11.2% EC and isopyrazam· azoxystrobin 29% SC have good control efficiency on powdery mildew of balsam pear, zucchini, melon and watermelon, which indicated that they are worthy of further research and development.
