Can Copper Oxychloride and Zineb Be Mixed with Other Pesticides?
Copper oxychloride-zineb is a copper protective fungicide that can be used on fruit trees and crops. Can copper oxychloride-zineb be mixed with other pesticides? Let's take a look together.
1. Can copper oxychloride-zineb be mixed with other pesticides?
It cannot be mixed with lime sulfur, resin soap, mineral oil emulsions, carbendazim, thiophanate and other agents. It cannot be mixed with strongly alkaline pesticides. It can be mixed and used immediately with most insecticides, acaricides and micro-fertilizers.
It can be used on fruit trees and crops, and is the copper formulation with the least phytotoxicity. After application, it rapidly destroys the pathogen's proteases and causes the pathogen to die, and can form a protective film on the plant surface. When used on crops such as potato, peanut and sunflower, it has the effect of stimulating growth and increasing yield. Copper oxychloride can also be compounded with other agents to form a variety of mixtures, such as copper oxychloride · kasugamycin, copper oxychloride · cymoxanil, copper oxychloride · metalaxyl, and copper oxychloride · zineb.
2. Targets of control
1. Apple speck disease, defoliation disease, brown spot disease, pear scab: after bagging, spray with 30% SC diluted 1000-1500 times, once every 15-20 days
