摘要
植物寄生线虫广泛存在于广西的甘蔗田中,对与甘蔗有关的主要病原线虫进行了鉴定共14个属,其中矮化线虫属(Tylenchorhynchus)和螺旋线虫属(Helicctylenchus)是广西蔗田中的优势种群。通过3年定点调查,蔗田中线虫的虫口密度在一年中呈现两个高峰。盆栽蔗接种试验表明,矮化线虫和螺旋线虫对甘蔗具有较强的致病性。3％呋喃丹颗粒剂对防治甘蔗线虫病比较有效。使用一种真菌制剂来防治甘蔗线虫,也有一定的效果。
Plant parasitic nematodes widely exist in the sugarcane fields of Guangxi Province. Fourteen genera which, relate to sugarcane were identified. Tylenchorhynchus and Helicotylenchus were the main species groups in these nematodes. In a three-year investigation in a cane field, plant parasitic nematodes appeared two high tides in numbers during a year period. Tylenchorhynchus and Helicotylenchus were highly pathogenic to sugarcane in the inoculation tests. Furandan(3% granular) was effective on nematode control. A certain extent of nematode control was obtained by using a fungus's nematocide in a plot trial.
