国外松枯梢病的综合控制技术

在福建闽侯县南屿林场的14～23年生发病的国外松种子园和试验林、用材林中,采用施肥防治、农药防治、综合防治等措施进行松枯梢病控制试验.结果表明:根施或叶面喷洒硼砂、根施或喷洒多菌灵、喷百菌清油烟利、燃放多菌灵等烟剂对松枯梢病有一定的防治效果;叶面喷施硼砂防效达67.5%,喷百菌清油烟剂的防效为69.7%,采用杀菌烟剂防效达66.1%;5种综合防治措施对松枯梢病有较好的控制作用,防治效果达69.5%～81.5%,尤其是采用清理病枯梢 根施硼肥 根施多菌灵的措施,防治效果达81.5%.

Study on Integrated Management of Shoot Dieback of Pine

Shoot dieback of pine damaged more than 20 pines,such as Pinus elliottii,Pinus taeda.To control its damage,tests for controlling shoot dieback of pine were in diseased 14~23 a seed orchard,trial forest,lumber forest of Nayu forest farm in Minhou county by applying fertilizer,pesticide and integrated management.The results showed that root application or spraying B fertilizer,root application or spraying carebendazin,spraying chlorlthalonil and applying carebendazin smoke had certain control effects.The control effect of spraying B fertilizer,chlorlthalonil and applying smoke reached 67.5%,69.7% and 66.1% respectively.Integrated management had better control effects which reached 69.5%~81.5%,especially the integrated management by clearing the disease shoot,root application of B fertilizer and carebendazin had control effect reaching 81.5%.
