Experiments were conducted to evaluate the efficacy of three currently available non-fumigant chemical nematicides (oxamyl, fluopyram, and fluensulfone) and a biological nematicide derived from against on tobacco in a growth room environment. The non-fumigant chemical nematicides greatly suppressed nematode egg production compared to the untreated control, the suppression being 99.9% for fluensulfone and oxamyl, and 93% for fluopyram. Similarly, oxamyl-, fluensulfone-, and fluopyram-treated pots, respectively, had 99%, 98%, and 94% less J2/100 cm of soil than those in the control. The biological nematicide did not have a significant effect on nematode egg production and the soil abundance of J2. The root biomass of tobacco was significantly reduced by the application of fluensulfone, while the effects of oxamyl, fluopyram, and metabolites were not significant compared to the untreated control. Results from this study suggest that non-fumigant nematicides have a potential to serve as an alternative to fumigant nematicides.
在生长室环境下进行了实验，以评估三种市售非熏蒸性化学杀线虫剂（杀线威、氟吡菌酰胺和氟噻虫砜）以及一种源自 的生物杀线虫剂对烟草上的 的防治效果。与未处理的对照相比，非熏蒸性化学杀线虫剂极大地抑制了线虫产卵，氟噻虫砜和杀线威的抑制率为99.9%，氟吡菌酰胺的抑制率为93%。同样，分别用杀线威、氟噻虫砜和氟吡菌酰胺处理的花盆中，每100厘米土壤中的J2数量分别比对照少99%、98%和94%。生物杀线虫剂对线虫产卵和土壤中J2的数量没有显著影响。施用氟噻虫砜显著降低了烟草的根生物量，而与未处理的对照相比，杀线威、氟吡菌酰胺和 代谢物的影响不显著。本研究结果表明，非熏蒸性杀线虫剂有可能作为熏蒸性杀线虫剂的替代品。
