摘　　要：从广东省番禺市胡萝卜根系及根际土分离到１ 种线虫，经鉴定为肾形肾状线虫Ｒｏｔｙｌｅｎｃｈｕｌｕｓ ｒｅｎｉｆｏｒｍｉｓ。该线虫在胡萝卜的生长期内，以１０～１１ 月份虫口密度最大，主要分布于０ ～１５ ｃｍ 土壤层。该线虫危害胡萝卜，是国内胡萝卜上的１ 种新病害。药剂试验表明供试的几种杀线剂均对肾形肾状线虫有较好的控制作用。The nematode separated from the root and the soil around root of carrot was identificated to be reniformis nematode Rotylenchulus reniformis. It distributed mostly in the soil depth from 0 to 15cm. The highest population density was in Qctober and November in growth season of carrot. Several nematicides could effectively control the reniformis nematode, but ethoprop compound B and E were more worth of application and extension in practice, based on the experiment.\;
