Three field experiments evaluated the performance of the nematicide fluensulfone against the potato cyst nematode Globodera pallida in Shropshire, England.
Experiments 1 and 2 showed reduced root infection and lowered multiplication of G. pallida following fluensulfone (Nimitz 15G(®) ) soil treatments at five rates (1.95, 3.00, 4.05 (full rate), 5.05 and 6.00 kg AI ha(-1) ) and Nimitz 480EC(®) at the full rate. Experiment 3 demonstrated a positive interaction between the full rate of Nimitz 15G and the potato variety Santé in the reduction of G. pallida. The fluensulfone treatments at the full rate had more consistent effects than the lower rates, and there were no greater effects for the treatments higher than this full rate. Generally, fluensulfone was less efficacious than oxamyl or fosthiazate, which suggests that the treatment may not be reliably integrated within shorter potato rotations.
The data suggest that fluensulfone soil application could make a useful addition to the few available nematicide treatments for the control of G. pallida rather than be a substitute for these treatments.© 2016 The Authors.

三项田间试验评估了杀线虫剂氟吡菌酰胺对英国什罗普郡马铃薯白线虫（Globodera pallida）的防治效果。
试验1和试验2表明，在以五种剂量（1.95、3.00、4.05（全剂量）、5.05和6.00千克有效成分/公顷）进行氟吡菌酰胺（Nimitz 15G®）土壤处理以及以全剂量使用Nimitz 480EC®后，根部感染减少，马铃薯白线虫的繁殖率降低。试验3表明，Nimitz 15G全剂量与马铃薯品种Santé在降低马铃薯白线虫数量方面存在积极的相互作用。全剂量的氟吡菌酰胺处理效果比低剂量处理更稳定，高于全剂量的处理未产生更大效果。总体而言，氟吡菌酰胺的效果不如杀线威或噻唑膦，这表明该处理在较短的马铃薯轮作中可能无法可靠地综合使用。
数据表明，土壤施用氟吡菌酰胺可为防治马铃薯白线虫的少数现有杀线虫剂处理方法增添有效补充，而非替代这些处理方法。© 2016作者。《害虫管理科学》由John Wiley & Sons Ltd代表化学工业协会出版。
