摘要
猕猴桃根结线虫病是危害猕猴桃的主要病害,株发病率达60％～70％,病情指数为18.12～21.50.1986～1988年期间笔者对此病作了初步的研究。根据病原线虫雌虫的会阴花纹特征,雄虫头部、口针的形态,2龄幼虫的长度,确定病原线虫为下列3个种:南方根结线虫(Meloidogyne incognita)爪哇根结线虫(M. jaranica),花生根结线虫(M. arenaria),其中以南方根结线虫为优势种,它1年发生6代。防治此病的药剂以力满库效果最佳。
Root-knot nematode disease is one of the serious diseases of kiwi fruit (Actinidia chinensis Planch.). The incidence of disease reaches 60 per cent to 70 per cent, and the infection index is from 18.12 to 21.5. A preliminary study on the disease was carried out from 1986 to 1988. Based on the perineal pattern of the adult female, head and stylet morphology of the male and length of two-age larva, the nematodes may be divided into three species: southern root-knot nematoda (Meloidogyne incognita Chit wood), Javanese root-knot nematoda (M. javanica) and peanut root-knot nematoda (M. arenaria). Among them southern root-knot nematoda is a predominent species, which can reproduce six generations in one year. Nemacur is the most efficient nematicide of all chemicals tested for this disease.
