由疫霉菌引起的橡胶树条溃疡病,曾在云南、广东主要植胶区发生过多次流行,严重影响橡胶生产。过去一直使用高毒农药赛力散或进口农药溃疡净(醋酸苯汞乳剂)作化学防治,取得良好的防治效果,但禁用汞制剂后,曾提出几种有效农药取代试用,均因存在某些缺点,未能全面推广使用,1979年我们用乙磷铝作防治橡胶树割面条溃疡病试验研究,经过几年来室内外药效测试和1981年大田12万株胶树生产性防治试验,效果良好,使用安全,药性稳定,对胶树产胶和割面无不良影响,于1982年通过鉴定,确定推广应用。
Rubber tree caused by Phytophthora ulcer disease, had in Yunnan, Guangdong, the main area of ?? rubber production have been many times the epidemic, a serious impact on rubber production. In the past, highly toxic pesticides were used to disperse or import pesticide ulcer net (phenylmercuric acetate emulsion) for chemical control and good control effects were obtained. However, after the mercury preparation was banned, several effective pesticide replacement tests have been proposed due to the existence of certain Shortcomings, failed to promote the use of 1979, we use phosphorous as a control rubber tree cut noodles ulcer disease test, after several years of indoor and outdoor efficacy test and 1981 Daejeon 120 000 plastic tree production control test, the effect is good, The use of safe, stable drug-free, gum rubber production and cutting surface without adverse effects, in 1982 through the identification, to determine the promotion and application.
