摘要
为了筛选防控甘蔗褐锈病的复合高效配方药剂及精准施药技术,选用代森锌、烯唑醇、代森锰锌、嘧菌脂、吡唑醚菌脂、苯甲嘧菌酯、百菌清、多菌灵进行田间药效试验。结果表明,(65%代森锌WP 1500 g+75%百菌清WP 1500 g+磷酸二氢钾2400 g+增效剂300 mL)/hm^(2)、(12.5%烯唑醇WP 1500 g+75%百菌清WP 1500 g+磷酸二氢钾2400 g+增效剂300 mL)/hm^(2)、(80%代森锰锌WP 1500 g+75%百菌清WP 1500 g+磷酸二氢钾2400 g+增效剂300 mL)/hm^(2)和(30%苯甲嘧菌酯SC 900 mL+磷酸二氢钾2400 g+增效剂300 mL)/hm^(2)等4个配方药剂对甘蔗褐锈病均具有良好的防治效果,其病指均在18.79以下、防效均达80.53%以上。本研究显示4个配方药剂是防控甘蔗褐锈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 the high-efficiency compound formula fungicides and the precise application technology for controlling sugarcane brown rust,a field efficiency trial was performed with eight fungicides,including zineb,diniconazole,mancozeb,azoxystrobin,pyraclostrobin,difenoconazole·azoxystrobin,chlorothalonil and carbendazim.The results showed that four formula fungicides,(1500 g of 65% zineb WP+1500 g of 75% chlorothalonil WP+2400 g KH2PO4+300 mL agricultural synergist)/hm^(2),(1500 g of 12.5% diniconazole WP+1500 g of 75% chlorothalonil WP+2400 g KH2PO4+300 mL agricultural synergist)/hm^(2),(1500 g of 80% mancozeb WP+1500 g of 75% chlorothalonil WP+2400 g KH2PO4+300 mL agricultural synergist)/hm^(2) and(900 mL 30% difenoconazole·azoxystrobin SC+2400 g KH2PO4+300 mL agricultural synergist)/hm^(2),had good control efficacy against sugarcane brown rust.The disease indexes of the four formula fungicides were below 18.79,and their control efficiency was above 80.53%.This study indicates that the four formula fungicides are the ideal high-efficiency compound formula for controlling sugarcane brown rust,which could be sprayed directly onto the leaves via artificial and unmanned aerial vehicles in July and August,with two single applications spaced 7 to 10 days apart.
