摘　　要：１９９３～１９９６年对陕西关中大蒜病虫害综合防治技术进行了研究，确定了以匐柄霉叶枯病和根蛆为主要防治对象，锈病、病毒病害、韭蛆、蓟马、绿圆跳虫、蒜萤叶甲等为兼治对象，提出了以农业防治为基础，药剂防治为重点的综防策略，确立了一套适用防治措施和田间防治历。主要防治措施包括调整作物和品种布局、选种、调节播种期、加强田间管理以及根据病虫监测结果适时施药等，提出了防治主要病虫的药剂、施药方式和经验防治指标以及进一步完善和发展综合防治技术的途径。In the years of 19931996, the integrated pest management of garlic (Allium sativum) in the Central Shaanxi was studied. The principal controlling targets of pest were Stemphylium leaf blight (Stemphylium vesicarium) and maggot (Delia antiqua, D. platura), and the secondary targets of pest management included Puccinia allii, garlic mosaic virus, garlic latent virus, Bradysia odoriphaga, B. luhi, Thrips tabaci, Sminthurus viridis, Galeruca reichardti etc. Also, the integrated management strategy with agricultural control as the base and chemical control as the key link was worked out. A set of management methods and the management schedule for field practice were set up. The important methods of management were rotation, reasonable deployment of cultivars, adjustment of planting date, improvement of cultivation and timely application of pesticides and fungicides according to the results of pest trapping and field survey. Also the appropriate pesticides and fungicides, their application methods and the experienced action thresholds for different pest and disease were suggested. Satisfied control results and notable economic benefits were obtained after the demonstration and application of the mentioned strategy and technical methods, the further improvements of the integrated pest management system were discussed.
