Pesticides have long been used in agricultural production and will continue to be used long into the future. Enhancing their efficient use in agricultural production is an effective method to avoid their loss to non-target areas, such as soil, water and air. Here natural green-peel orange essential oil (GOEO) was used as a spray adjuvant to improve the efficient use of pesticides. A comparative study between a conventional formulation and a conventional formulation with GOEO was conducted. Conventional formulations of prochloraz were chosen as control groups. It was obvious that the concentrations of prochloraz and its metabolite in cucumber leaves treated by conventional formulations with GOEO were much higher than those treated without GOEO. The data also showed, for both emulsifiable concentrate (EC) and suspension concentrate (SC), that the spreading and penetration performance were improved when GOEO was used as a spray adjuvant, but with SC the impact was more significant. GOEO improved the deposition, absorption and degradation performance of prochloraz on cucumber leaves. It was more applicable to those pesticide formulations without a good wetting and spreading effect, such as SC. As a plant source extract, GOEO is much safer for crops and more friendly to the environment than other synthetic adjuvants. The application of GOEO as a spray adjuvant has great potential to increase the pesticide utilization rate.
农药长期以来一直用于农业生产，并且在未来很长一段时间内仍将继续使用。提高其在农业生产中的使用效率是避免其流失到非目标区域（如土壤、水和空气）的有效方法。在此，天然青皮橙精油（GOEO）被用作喷雾助剂以提高农药的使用效率。对常规制剂和添加GOEO的常规制剂进行了对比研究。选择咪鲜胺常规制剂作为对照组。显然，添加GOEO的常规制剂处理的黄瓜叶片中咪鲜胺及其代谢物的浓度远高于未添加GOEO处理的叶片。数据还表明，对于乳油（EC）和悬浮剂（SC），当使用GOEO作为喷雾助剂时，铺展和渗透性能均得到改善，但对于SC，影响更为显著。GOEO提高了咪鲜胺在黄瓜叶片上的沉积、吸收和降解性能。它更适用于那些润湿性和铺展性不佳的农药制剂，如SC。作为一种植物源提取物，GOEO对作物更安全，对环境比其他合成助剂更友好。将GOEO用作喷雾助剂在提高农药利用率方面具有巨大潜力。
