General principles for the mixing of chitin fertilizers and pesticides :
1. Pay attention to the mixing sequence : first dilute the chitin product according to the usage instructions, then dilute the pesticide into the mother liquor, and finally pour the pesticide mother liquor into the chitin dilution. The order of compounding cannot be reversed.
2, pay attention to the current distribution
1. Prohibit the mixing of the raw material or raw powder of chitin with the original or original powder of the pesticide.
2. Chitin is mixed with copper preparation and manganese zinc preparation.
For example, chitin should not be directly mixed with copper preparations, mancozeb, propidium zinc, ethylphosphorus and other metal-containing fungicides . If mixed, the chitin product should be diluted according to the use ratio, and then the fungicide. Dilute into the mother liquor and then pour the fungicide mother liquor into the chitin diluent. For example, in the apple tree, a protective fungicide (mainly mancozeb) is used for disease prevention. In order to avoid the reaction of mixing, the above compounding method is adopted.
Chitin with methyl thiophanate, chlorothalonil, carbendazim, thiram, chlorhexidine, carbendazim, metalaxyl, flusilazole, pyrimethanil, streptomycin, neutrophin, polyclonal antibody When most of the single-component fungicides such as mycin are mixed, it is also necessary to prepare the mother liquor in advance and then mix.
Third, mixed with pesticides
In practical applications, if the chitin product is directly mixed with the avermectin product for foliar spray, it may cause phytotoxicity. This may be due to the fact that the two liquids have not been diluted separately or are not ready for use. The same two products, for the application of irrigation or rooting, no phytotoxicity was found, which is related to the degree of dilution of the product and the order of mixing after the mother liquor.
At present, chitin can be mixed with organic fertilizers, biological fertilizers and chemical fertilizers on the market, and has a significant synergistic effect. When chitin is mixed with single element micro-fertilizer and whole nutrient micro-fertilizer, the mixing order should also be paid attention to. The chitin product should be diluted in multiples according to the instructions. Then the micro-fertilizer is diluted into mother liquor, and finally the micro-fertilizer mother liquid is poured into the shell. In the dilution. The order of mixing can still not be reversed.
