油梨樟疫霉菌根腐病生物防治探讨

Study on bio-control for of avocado root rot by camphor fungus

樟疫霉菌分布广、寄主也很多,虽然被危害的植物表现的症状不大相同,但大多数是危害植物的根部,并且在大豆等植物根病上的生物防治上取得可喜成效。樟疫霉菌危害油梨主要是引起根腐病,在防治上目前以化防为主,效果不佳,而在油梨根病上采用生物防防治较少。文章主要介绍樟疫霉菌的危害、生防机制及在油梨樟疫霉菌根腐病采用生防的可能性。

Camphor fungus is wide distribution, so as many of the host. Although the symptoms performance of ill plant is different, but most of plant is harmed by the roots, and achieved satisfactory results by bio-con- trol. The performance of avocados infection by camphor fungus is mainly cause root rot, the countermeasure is gave priority to prevention, which achieve poor effect, while bio-control rarely reported. This paper mainly introduces the harm of the camphor fungus, bio-control mechanisms, and the possible of bio-eontrol for avo- cado root rot.
