摘　　要：为了筛选防控甘蔗褐条病的复合高效配方药剂及精准施药技术,选用多菌灵、苯菌灵、百菌清、嘧菌脂、吡唑醚菌脂、苯甲嘧菌酯进行田间药效试验。结果表明,(50%多菌灵可湿性粉剂1500 g+75%百菌清可湿性粉剂1500 g+磷酸二氢钾2400 g+农用增效助剂300 mL)/hm2、(50%苯菌灵可湿性粉剂1500 g+75%百菌清可湿性粉剂1500 g+磷酸二氢钾2400 g+农用增效助剂300 mL)/hm2和(25%吡唑醚菌脂悬浮剂600 mL+磷酸二氢钾2400 g+农用增效助剂300 mL)/hm2等3个配方药剂对甘蔗褐条病均具有良好的防治效果,其病指均在14.02以下,防效均达84.41%以上。本研究显示3个配方药剂是防控甘蔗褐条病理想的复合高效配方药剂,可在7—8月人工和无人机飞防叶面喷施,7~10天喷1次,连喷2次。To screen high-efficiency compound formula fungicides and study their precise application technology for controlling sugarcane brown stripe disease, carbendazim, benomyl, chlorothalonil, azoxystrobin,pyraclostrobin and difenoconazole·azoxystrobin were selected for the field efficacy test. The results show that three formula fungicides:(1500 g of 50% carbendazim WP + 1500 g of 75% chlorothalonil WP + 2400 g KH2PO4 + 300 mL agricultural synergist)/hm2,(1500 g of 50% benomyl WP + 1500 g of 75% chlorothalonil WP + 2400 g KH2PO4 + 300 mL agricultural synergist)/hm2, and(600 mL of 25% pyraclostrobin SC + 2400 g KH2PO4 + 300 mL agricultural synergist)/hm2 have good control efficacy against sugarcane brown stripe disease, the disease indexes are all below 14.02 and the control effects are all above 84.41%. This study indicates that these three formula fungicides are the ideal high-efficiency compound formula fungicides for controlling brown stripe disease, which can be sprayed onto the leaves by artificial and unmanned aerial vehicle in July and August, with twice in succession spaced 7 to 10 days apart.
