除草剂喷雾过程中的兑水量是影响除草剂药效的重要因素。通过温室试验和田间试验研究了不同兑水量条件下甲基化大豆油（ MSO）助剂对苯唑草酮药效及玉米产量的影响情况，结果表明：温室条件下，MSO助剂的加入显著提高了苯唑草酮对狗尾草、牛筋草和苘麻的防治效果，兑水量的降低并没有显著降低药效；田间试验结果也表明，MSO的加入均显著提高了苯唑草酮对阔叶杂草、禾本科杂草以及杂草总量的防效，兑水量的降低并没有对药效产生显著影响，而且对玉米产量也没有影响。由此说明，在苯唑草酮使用过程中适当降低兑水量， MSO助剂对其增效效果不会降低。

Spray volume is an important factor influencing the efficacy of herbicides .Greenhouse and field experiments were conducted to study the effect of methylated soybean oil ( MSO) on the efficacy of topramezone and the maize grain yield applied at different volumes .MSO significantly enhanced the efficacy of topramezone on Setaria faberii Herrm,Ele-usine indica L.and Abutilon theophrasti Medic.under greenhouse conditions ,and the efficacy was not significantly de-creased by reducing the spray volume .In the field,MSO also significantly enhanced the efficacy of topramezone on broad-leaf weeds ,grass weeds and total of weeds ,while the reduction of spray volume did not influence the efficacy significantly at all,and the grain yield of maize was also not affected .We can conclude that MSO enhances topramezone efficacy even when the spray volume is reduced .
