There are many types of pesticides now, so we should pay attention to the use of pesticides.
Only after these basic methods know the technology, will it not affect the chemical reaction of pesticide products, but how to use it normally, the editor will give you a detailed explanation below
.
Acid-base pesticides cannot be mixed.
Commonly used pesticides are generally divided into three categories: acidic, alkaline and neutral
.
Sodium fluoride lead acid, lead arsenate, etc.
are neutral pesticides
.
Copper sulfate, sodium fluorosilicate, white arsenic, superphosphate, etc.
are acid pesticides
.
Rosin mixture, lime sulfur mixture, Bordeaux mixture, aluminum arsenate, soap, lime, lime nitrogen, etc.
are alkaline
.
Mixing acid and alkaline pesticides will decompose and destroy, reduce efficacy, and even cause phytotoxicity
.
Most organophosphorus pesticides such as dimethoate, pyrethrum, malathion, ammonium phosphate, etc.
and some microbial pesticides such as kasugamycin, jinggangmycin, blasticidin, etc.
, as well as Zhudaojing, mancozeb , With sen ammonium, etc.
, can not be mixed with alkaline pesticides
.
After the pesticides are mixed, the pesticides that cause phytotoxicity on crops cannot be applied separately with Bordeaux mixture and lime sulfur mixture after the pesticides are mixed.
They can prevent and control a variety of diseases, but they quickly undergo chemical changes after mixing, resulting in dark brown copper sulfide precipitation
.
This not only destroys the original bactericidal ability of the two drugs, but also the copper sulfide produced will further produce copper ions, causing plants to fall leaves and fruit, leaves and fruit burns, or dry shrinkage and other serious phytotoxicity phenomena
.
The mixing of different pesticides is prone to chemical reactions.
Therefore, under normal circumstances, pesticides cannot be mixed.
If pesticides must be mixed, it is necessary to master the specific product characteristics and scientifically match them to achieve the desired effect
