铜制剂是一类无公害、无残留、不产生抗药性的农药,对常见的真菌、细菌可同时杀灭,因而杀菌范围广。在当前农作物无公害栽培技术推广中,铜制剂可大派用场。一、可杀得有效成分为氢氧化铜,是新型的铜制剂,药液配制后稳定,扩散性好,粘附性强,耐雨水冲刷,能稳定地缓慢释放出杀菌成分二价铜离子,对农作物不产生 Copper is a type of pollution-free, non-residue, does not produce resistance to pesticides, common fungi, bacteria can kill at the same time, and thus a wide range of sterilization. In the current crop pollution-free cultivation technology promotion, the copper preparation can be useful. First, can kill the active ingredient is copper hydroxide, is a new type of copper preparation, liquid stability after preparation, good diffusion, strong adhesion, resistance to rain erosion, stable and slow release of biocidal ingredients bivalent copper ions, Not for crops
