含铜杀菌剂是哮治咖啡锈病最主要的农药,其防效明显,使咖啡增产较多。其中的波尔多液属土农药,来源方便,成本低,粘着力强,还能供给咖啡微量元素铜营养,有良好的滋补效应,可增加叶片光合率,延缓叶片老化,防止叶片脱落,促进植物生长,使产量增加明显,并且还能结合根外追肥和选择性落叶剂喷布。用内吸治疗剂防治咖啡锈病,以粉锈宁的防效最好。它能铲除叶组织内菌丝及抑制孢子生成,且残效期特长,将波尔多液与粉锈宁交替使用,可取长补短。使用波尔多液防治咖啡锈病以碱性的防效最好。在云南和海南防治咖啡锈病每年喷药2～3次即可。雨水溅散能使叶面药剂再分布,故防治咖啡锈病,不必强调专喷叶背,因而大面积防治完全可能采用机械喷药。
Copper fungicide is the most important pesticide for asthma treatment of coffee rust, its obvious effect, so that more coffee production. Among them, Bordeaux is a liquid pesticide with convenient source, low cost and strong adhesive force. It can also provide copper nutrition for coffee trace elements, has good nourishing effect, increases photosynthetic rate of leaves, delays leaf aging, prevents leaves from falling off and promotes plant growth , So that the output increased significantly, but also with the top dressing and selective deciduous spray. With the absorption of therapeutic agents to control coffee rust, Fening Ning best anti-control effect. It can eradicate the mycelium in the leaf tissue and inhibit the spore formation, and the residual effect of long-term, the Bordeaux mixture and triadimefon alternate use, learn from each other. The use of Bordeaux solution to control coffee rust alkaline to control the best. In Yunnan and Hainan prevention and control of coffee rust spraying 2 to 3 times a year. Sprinkling of rain can make the leaf redistribution of drugs, so the prevention and treatment of coffee rust, do not have to emphasize the special spraying leaves back, so a large area of prevention and treatment may be the use of mechanical spraying.
