1983年2月,根线虫(Pratylenchus penetrans [Cobb] Chilwood and Oteifa)在澳大利亚首次记录于维多利亚(Victaria)雷尼克(Rennick)大型森林圃的辐射松(Pinus radiata D. Don)幼苗上,地点靠近南澳大利亚(South Australia)边界的芒特甘比尔(Mi Gambier) (Winoto-Suatmadji and Marks 1983)。这种线虫在荷兰(Netherlands)、比利时(Belgium)、加拿大(Canada)、日本(Japan)和德国(Germany)的针叶树苗圃内能引起幼苗矮化病,在维多利亚,它对仁果类和核果类苗圃可导致严重损失(Winoto-Suatmadji and Marks 1983)。本文主要叙述辐射松幼苗受根线虫侵害后生长不良的情况。线虫种的鉴定和描述、致病性试验、病害损失估计以及某些防治措施的试验结果。
In February 1983, Pratylenchus penetrans [Cobb] Chilwood and Oteifa were first recorded in Australia on Pinus radiata D. Don seedlings in the large Rennick forest park in Victaria, near the south Mi Gambier on the border of South Australia (Winoto-Suatmadji and Marks 1983). This nematode can cause seedling dwarfism in conifer nurseries in the Netherlands, Belgium, Canada, Japan and Germany, and in Victoria, it affects both pome and drupe Nurseries can cause serious damage (Winoto-Suatmadji and Marks 1983). This article describes the growth of radix pine seedlings damaged by root nematodes. Identification and description of nematode species, pathogenicity tests, estimation of disease losses, and test results of certain control measures.
