Embodiment 130

[0036] Embodiment 130% mancozeb and 20% aluminum triethylphosphonate compound wettable powder

[0037] Mancozeb technical 30%, aluminum triethylphosphonate technical 20%, dispersant sodium lignosulfonate 7%, wetting agent alkylnaphthalene sulfonate 2%, deflocculant sodium tripolyphosphate 2% , stabilizer urotropine 1%, glidant white carbon black 1.5%, silicon and ether graft defoamer 0.5%, and the rest is filled with filler kaolin. Weigh the amount of each component according to the formula, mix them uniformly, and then carry out ultrafine pulverization through a jet mill with a pulverization pressure of 0.8-1Mpa, and finally classify the collected materials through a 45 μm test sieve, and mix them uniformly again to obtain 30% mancozeb and 20% aluminum triethylphosphonate compound wettable powder.

[0038] The 50% mancozeb·aluminum triethylphosphonate wettable powder prepared in Example 1 is detected, and the quality index detection results are shown in Table 1.

Abstract

Disclosed is wettable powder compounded of mancozeb and fosetyl-aluminium and a preparation method of the wettable powder. The wettable powder comprises, by mass percentage: original drugs of mancozeb and fosetyl-aluminium, a dispersant, a wetting agent, a deflocculant, a stabilizing agent, a glidant, an antifoaming agent, and a filler. The preparation method comprises: (1) weighing the following raw materials: the original drugs of mancozeb and fosetyl-aluminium, the dispersant, the wetting agent, the deflocculant, the stabilizing agent, the glidant, the antifoaming agent, and the filler, and uniformly mixing the raw materials; and (2) performing superfine grinding of the raw materials through a jet mill, grading the obtained product through a 45-micron test sieve, and uniformly mixing the obtained product. The wettable powder is simple in process, low in cost, convenient to store and transport, safe, and stable in property, has advantages of less application amount, wide bactericidal spectrum, quick effect, complete sterilization, low residue, and effective postponing of generation of a pathogen antibody, and is an excellent chemical bactericide.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a wettable powder compounded with mancozeb and aluminum triethylphosphonate and a preparation method thereof. Background technique [0002] Wettable powder is a dosage form in which the original pesticide, inert filler and a certain amount of additives are mixed in a certain proportion and fully pulverized to reach a certain fineness. From the point of view of shape, it is no different from powder, but because of the addition of additives such as dispersant and wetting agent, it can be wetted, dispersed by water after being added to water, and can be sprayed to form a suspension. Compared with emulsifiable concentrate, wettable powder has low production cost and can be packaged in paper bags or plastic bags, which is convenient and safe for storage and transportation, and the packaging materials are easier to handle; more importantly, wettable powder does not use solvents and emulsifier...
