Fertilizer cannot be mixed
(Reporter Chen Yuzhen) How can farmers ensure drug efficacy when using pesticides and fertilizers? The city’s Consumer Council issued its Consumer Alert No. 11 in 2007 to remind farmers that pesticides and chemical fertilizers cannot be used together. The application of “four non-mixed†principles is a must. According to the introduction of relevant personnel from the City Supply and Marketing Cooperative, the principle of pesticides and chemical fertilizers is the following: First, alkaline fertilizers such as ammonia, lime, and ash cannot cope with trichlorfon, imperialiste, thiophanate, jinggangmycin, and multi-bacteria. The use of pesticides such as Ling, Yeyu San, and pyrethroid insecticides will reduce the efficacy of the medicine. The second is alkaline pesticide lime sulfur, Bordeaux mixture, pine resin mixture, etc., can not be mixed with ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium chloride and other ammonium nitrogen fertilizer and calcium superphosphate and other fertilizers, otherwise it will cause loss of ammonia volatilization, Reduce fertilizer effect. Third, arsenic-containing pesticides, such as calcium arsenate and aluminum arsenate, cannot be mixed with potassium salts and sodium salts. Otherwise, soluble arsenic will be produced and phytotoxicity will occur. Fourth, chemical fertilizers can not be mixed with microbial pesticides, because chemical fertilizers are volatile and corrosive. If they are mixed with microbial pesticides such as A. cereus and Bacillus spp., it is easy to kill microorganisms and reduce the control effect.
