| 摘 要： | 针对苹果斑点落叶病防治(以保护性杀菌剂为主)已出现耐药或抗药性问题及苹果产业对农药剂型环保的要求,研究5%己唑醇微乳剂不同施药剂量对苹果斑点落叶病的防治效果及对苹果树安全性的影响。结果表明,在苹果树结果期(6月下旬),当病害处于发病初期时,使用5%己唑醇微乳剂33.3～50.0 mg/kg进行处理,防效可达80%以上,相当于或略好于对照药剂5%己唑醇可湿性粉剂33.3 mg/kg,公顷用药液量2 925 kg,对苹果树安全。建议使用剂量为33.3～50.0 mg/kg(1 000～1 500倍)。

| Abstract: | In view of apple alternaria blotch with protective fungicide as main force,and a variety of fungicides have the emergence of tolerance or resistance problem and apple industry on pesticide environmental requirements,study on control effect of 5% hexaconazole micro-emulsion at different doses on apple alternaria blotch and and apple safety was conducted.The results show that,in the apple tree fruiting period late June,when the disease is at the initial stage,the use of 5% hexaconazole micro-emulsion 33.3～50.0 mg/kg,for the first time,foliar spraying,after every 7 d use a common medicine,total 3 times,spray uniform,control efficiency could reach more than 80%,equivalent to or slightly better than control insecticide of 5% hexaconazole wettable powder 33.3 mg/kg,per hectare medicine liquid volume 2 925 kg,it is safe to apple tree.Recommended dosage of 33.3～50.0 mg/kg(1 000～1 500 times). |
