摘要
为探究新型杀线剂氟吡菌酰胺对烟草根结线虫病的防效及对烟株生长的影响,2019年研究组在黔西县林泉镇清塘村进行了田间试验,通过病情指数、防治效果以及农艺性状等指标综合评价41.7%氟吡菌酰胺悬浮剂不同用量对烟草根结线虫病的防效及烟株生长的影响。结果表明:使用41.7%氟吡菌酰胺悬浮剂0.05~0.07 mL/株,兑水500 mL后灌根,对烟草根结线虫病的防效为65.94%~68.27%,显著高于常规药剂(10%噻唑膦颗粒剂);该悬浮剂还能明显增强烟草成熟期株高、茎围、最大叶片长、宽、有效叶片数等农艺性状。
In order to explore the control effect of a new nematicide fluopyram on tobaccoroot-knot nematode and its impact on the growth of tobacco,a field experiment was evaluated on the effect of 41.7%fluopyram SC on the tobaccoroot-knot nematodes based on the disease index,control effect and its impact on agronomic trait.This study was conducted in qingtang village,Linquan Town,Qianxi county,Bijie City,in 2019.The results showed that the control effect of 41.7%fluopyram SC of 0.05~0.07 mL per plant mixed with 500 mL water on the root against root-knot nematode was 65.94%~68.27%,which was significantly higher than that of conventional medicament,10%fosthiazate GR;41.7%fluopyram SC significantly enhanced the agronomic characteristics of tobacco in the maturation period,such as plant height,stem circumference,maximum leaf length and width,and effective number of leaves.
