果树植物寄生线虫的药剂防治

Effects of Chemicals on Controlling Nematodes Parasizing Fruit Trees

利用药剂对植物寄生线虫进行防治研究结果表明：铁灭克（法）６９ｋｇ／ｈａ、克线磷８２．５ｋｇ／ｈａ或霸杀脒４８ｋｇ／ｈａ对Ｔｙｌｅｎｃｈｕｌｕｓｓｅｍｉｐｅｎｅｔｒａｎｓ、Ｐｒａｔｙｌｅｎｃｈｕｓｓｃｒｉ－ｈａｅｒｉ和Ｐ．ｐｅｎｅｔｒａｎｓ的防治效果最佳，国产铁灭克６９ｋｇ／ｈａ、克线磷４２ｋｇ／ｈａ和铁灭克（法）３４．５ｋｇ／ｈａ次之，而呋喃丹和霸杀脒２４ｋｇ／ｈａ较差；５种药剂对３种线虫持效期测定结果，克线磷、铁灭克（法）和国产铁灭克最长为１８０天，其次是霸杀脒，为１２０～１８０天，呋喃丹最短。

The efficiency of nematocides in controling nematodes were studied.The results showed that, for controlling Tylenchulus semipenetrans,Pratylenchus scrihaeri and P.Penetrans parasizing fruit trees,69kg/ha of Temik produced in China,42kg/ha of phenamiphos or 34.5kg/ha of Temik produced in France displayed the best efficiency,but 24kg/ha of Furadan or 24kg/ha of Basamid did not do very wellActive duration of phenamiphos,Temik produced in France and China were the longest(180 days);that of Basimid was shorter(120～180 days)and that of Frandan was the shortest,only 60 days.
