Mancozeb and difenoconazole compounded wettable powder and preparation method thereof

Abstract

The invention discloses mancozeb and difenoconazole compounded wettable powder and a preparation method thereof, which belongs to the field of pesticide preparations. The mancozeb and difenoconazole compounded wettable powder is prepared from the following raw materials by weight percent: 50 to 60 percent of mancozeb, 5 to 10 percent of difenoconazole, 2 to 5 percent of sodium thiosulfate, 2 to 5percent of sodium salicylate, 5 to 8 percent of disodium tridecanol sulfosuccinate, 2 to 6 percent of polyoxyethylene carboxylate, 0.5 to 2 percent of nekal, and the balance of diatomite. The wettablepowder has the advantages of high suspension rate, short wetting time, no agglomeration, good pesticide effect and the like.

Description

Technical field [0001] The invention relates to the technical field of pesticide processing, in particular to a wettable powder prepared by mancozeb and difenoconazole and a preparation method thereof. Background technique [0002] Mancozeb (see structural formula I) is an excellent protective fungicide and a low-toxic pesticide. Because of its wide range of sterilization and resistance to resistance, its control effect is significantly better than other similar fungicides, so the international consumption has always been a large-tonnage product. At present, most of the domestic compound fungicides are processed and formulated by mancozeb. The trace elements of manganese and zinc have obvious effects on crop growth and yield increase. Through more than ten years of field application, they can prevent and control pear scab and apple. Spot leaf disease, melon and vegetable diseases, downy mildew, field crop rust, etc. have significant effects. The disease can be effectively contro...

AI Technical Summary

Problems solved by technology

my country has produced wettable powder pesticides for decades, but the problems of wettable powder pesticide agglomeration, low suspension rate, and long wetting time have always plagued the majority of pesticide manufacturers. Most manufacturers often make pesticides due to the above problems. The stability of the product is poor, and more anti-caking agent white carbon black is added to the formula, but the effect is not ideal, the drug effect is not good, the original drug and additives are wasted, and the cost of agricultural production is increased.
