桶混助剂通过改善农药在植物叶面上的附着 ,展布或吸收而能够极大地提高药效 ,但并非任何助剂对任何农药均有效。如果说提高药液附着对所有农药均有利 ,那么获得卓越的药液展布性对保护性杀菌剂尤为重要。表面活性剂对农药叶面吸收的影响更复杂 ,与其亲水基及亲脂基结构以及浓度均有关系。因此选择桶混助剂时 ,既要考虑农药本身的理化性质 ,又要考虑靶标植物的叶片表面特征
Barrel additives can greatly improve efficacy by improving the attachment, spreading or absorption of pesticides on plant foliage, but not any adjuvant is effective with any pesticide. If it is beneficial for all pesticides to improve chemical attachment, it is especially important for protective fungicides to obtain excellent spreading of the chemicals. The effect of surfactant on the absorption of pesticide foliar surface is more complicated, which is related to its hydrophilic and lipophilic structure and concentration. Therefore, the choice of barrels of additives, it is necessary to consider the physical and chemical properties of pesticides themselves, but also consider the target plant leaf surface characteristics
