Field Efficacy Trials of Glyphosate 41SL Against Weeds in Citrus Orchard

对41%草甘膦异丙胺盐水剂防除柑橘园杂草进行田间药效试验。结果表明,安徽省国家农药剂型工程技术中心生产的41%草甘膦异丙胺盐水剂对桔园内狗牙根、小飞蓬、蛇莓等常见的单、双子叶杂草均有理想的防效,30天株防效99.35%,鲜重防效98.68%。安徽省国家农药剂型工程技术中心提供的41%草甘膦异丙胺盐水剂具有安全、高效、药效期长等优点,适合作为柑橘园杂草的防除药剂,推荐施药剂量(制剂量)为4.573 2 L/hm2。

Glyphosate 41SL was applied to control weeds in the fieht experiment. The results showed that the control effects of Glyphosate 41SL produced by Anhui National Technology and Engineering Centre of Pesticide Formulation were good at common monocotyledonous and dicotyledonous weeds in citrus orchard such as Cynodondactylon（Linn.）Pers., Conyza canadensis （L.） Cronq., Duchesnea indica （Andrews）Focke and so on. The stem control effect and fresh weight effect were 99.35% and 98.68% respectively after 30 days. Glyphosate 41SL produced by Anhui National Technology and Engineering Centre of Pesticide Formulation had many advantages of safety, high efficiency and long expiry date, so it was suitable for control weeds in citrus orchard.
