摘要
草甘膦异丙胺盐药液中分别加入九种助剂后对空心莲子草喷雾处理 ,测定植株鲜重及再生植株鲜重 ,并测定药液的表面张力。结果表明 ,药液中助剂UC - 12、TL - 80 0、JFC、Tween2 0的浓度达到 10 0 0～ 5 0 0 0mg/L时鲜重抑制率比CK提高了 6～ 2 0个百分点。加入UC - 12、JFC对根茎抑制作用最为明显 ,复发率降低了约 12个百分点。九种助剂降低药液表面张力的效能从高到低顺序为 :农乳 5 0 0 >90 4>APG >JFC >TL80 0 >UC - 12 >Tween2 0 >961>SD。上述试验结果表明 ,助剂UC - 12、TL - 80 0、JFC、Tween2 0对草甘膦的增效作用较为显著 。
Alligator Weed 〔Alternanthera philoxeroides (Mart ) Griseb 〕 was treated with glyphosate isopropylamine salt and nine adjuvants,respectively The results indicated that adjuvant UC-12?TL-800?JFC?Tween20 were most effective,inhibition to fresh weight was increased by 6-20 percent,inhibition to root regrowth was increased by 8-12 percent,when glyphosate was mixed with this adjuvants The efficacy of reducing surface tension of glyphosate solution was by this order:Nonlu500>904>APG>JFC>TL800>UC-12>Tween20>961>SD There were no close relationship between synergism of adjuvants and surface tension reducing level
