果树植物寄生线虫药剂防治研究

Effects of Chemicals on the Control of Nematodes for Fruit Trees

对果树植物寄生线虫应用几种药剂进行防治研究，结果表明：铁灭克（法）4．6kg·666．7m-2、克线磷5．5kg·666．7m-2和霸杀脒3．2kg·666．7m-2对柑桔根线虫（Tylenchulussemipenetrans）、苹果根腐线虫（Pratylenchusscribneri）和梨穿刺根腐线虫（Pratylenchuspenetrans）的防治效果最佳，国产铁灭克4．6kg·666．7m-2、克线磷2．8kg·666．7m-2和铁灭克（法）2．3km·666．7m-2次之，而呋喃丹较差；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180d，其次是霸杀眯为120～180d，呋喃丹最短，仅60d。

Different chemicals were used for control of Tylenchulus semipenetrans, Pratylenchus scribneri and P. penetrans parasiting nematodes. Results showed Temik4. 6kg·666. 7m-2 (produced in China ), Phenami Phos 2.8kg·666. 7m-2 and Temik 2.3kg·666. 7m-2 (produced inFrance) displayed the best efficiency,while Furadan 1. 6kg·666. 7m-2 and Basamid 1. 6kg·666. 7m-2 did not do very well. The active duration of Phenami Phos,Temik produced in France and China were the longest (180 days ),while the Basimid,Furadan and Bhortes only 120 or 60 days.
