1.酸碱度是影响各组分有效性的重要因素。在碱性条件下,氨基甲酸酯、拟除虫菊酯类杀虫剂,福美双、代森环等二硫代氨基甲酸类杀菌剂易发生水解或复杂的化学变化,从而破坏原有结构。在酸性条件下,2,4-D钠盐、2甲4氯钠盐等会分解,因而降低药效。2.有机硫类和有机磷类农药不能与含铜制剂的农药混用。如二硫
1. pH is an important factor affecting the effectiveness of each component. Under alkaline conditions, carbamic acid esters, pyrethroid insecticides, thiram, dendrones and other dithiocarbamate fungicides prone to hydrolysis or complex chemical changes, thus undermining the original structure. Under acidic conditions, 2,4-D sodium salt, 2 A 4 chlorine sodium salt will decompose, thus reducing the efficacy. 2. Organic sulfur and organic phosphorus pesticides can not be mixed with pesticides containing copper preparations. Such as disulfide
