【摘要】 柑桔园行间定向喷雾试验结果表明,在41%农达AS中加入70%苯嘧磺草胺WG和助剂Dash不仅能有效控制乌蔹莓、铁苋菜、假一年蓬、加拿大一枝黄花等多种耐草甘膦阔叶杂草的危害,控制多年生杂草的再生,而且作用速度可与20%克无踪AS相当,对柑桔生长安全。从高效、经济、安全的角度综合考虑,三者混用的适宜剂量为41%农达AS 1 000~1 500 g ai/hm2+70%苯嘧磺草胺WG 12.5~25.0 g ai/hm2+助剂Dash(喷液量的1%)。更多还原

【Abstract】 The directed inter-row spraying experiment was conducted in an orangery to control weeds resistant to glyphosate.The results showed that 41% glyphosate AS(1 000～1 500 g aihm2)+70% saflufenacil WG(12.5～25.0 g aihm2)+adjuvant Dash(1% of spray liquid volume) could not only effectively control the damage caused by such glyphosate-resistant broadleaf weeds as Cayratia japonica,Acalypha australis,Erigeron philadelphicus and Solidago canadensis and the regeneration of perennial weeds,but also be equivalent to 20% paraquat AS in control speed and safe for the orange growth.更多还原
