在南非,植物寄生线虫是一种为害菠萝的常见害虫,它往往使菠萝严重减产。当前防治线虫的措施,是使用如二溴乙烷、1.3—二氯丙烷、1.2—二氯丙烷合剂和二溴氯丙烷之类的土壤熏蒸剂。本文报道在东好望角巴得斯特地区所进行的两个试验的结果。比较了几种土壤熏剂对无刺卡因种菠萝产量的影响。 In South Africa, the plant parasitic nematode is a common pest of pineapples, which often causes serious pineapple losses. Current control measures against nematodes are the use of soil fumigants such as dibromoethane, 1.3-dichloropropane, 1.2-dichloropropane and dibromochloropropane. This paper reports the results of two trials conducted in the area of ​​Bad Astod, East Cape. The effects of several soil fumigants on the yield of pineapple without acaridin were compared.
