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.

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 compounded with mancozeb and difenoconazole and a preparation method thereof. Background technique [0002] Mancozeb (see structural formula I) is an excellent protective fungicide, which is a low-toxicity pesticide. Because of its wide bactericidal range, not easy to produce resistance, and its control effect is obviously better than other similar fungicides, it has always been a large-tonnage product in the international market. At present, most domestic compound fungicides are processed and formulated with mancozeb. The trace elements of manganese and zinc have obvious effects on promoting the growth and increasing yield of crops. Spot defoliation, melon and vegetable blight, downy mildew, field crop rust, etc. have remarkable effects, and can effectively control the occurrence of diseases without any other fungicides, and the quality is stable ...
