The combination of chemical fertilizers and pesticides can provide crop nutrients, disease prevention, pest control and weed control. It is a widely used technology in recent years. However, chemical fertilizers and pesticides are also incompatible with each other. Some fertilizers and pesticides cannot be mixed. Here are some tips on which fertilizers and pesticides can't be mixed?
one. Alkaline fertilizer ammonia water, lime nitrogen, grass ash, etc. can not be acidic with trichlorfon, dimethoate, methamidophos, acesulfame, thiophanate, carbendazim, Jinggangmycin, yam, and pyrethroid insecticides . Mix pesticides.
two. Alkaline pesticide stone flow agent, Bordeaux mixture, and rosin mixture cannot be mixed with ammonium fertilizer such as ammonium bicarbonate, ammonium sulfate or ammonium nitrate or acidic fertilizer such as superphosphate.
three. Arsenic-containing pesticides, such as calcium arsenate and aluminum arsenate, cannot be mixed with fertilizers containing potassium or sodium salts, otherwise soluble arsenic may be produced and phytotoxicity may occur.
four. Chemical fertilizers cannot be mixed with microbial pesticides because chemical fertilizers are volatile and highly corrosive. If mixed with microbial pesticides and insecticides, they are easy to kill microorganisms and reduce the control effect.
