Embodiment 1
[0035] A benomyl wettable powder, its formula is (wt%): benomyl 50.0%, dispersant calcium lignosulfonate 3.75%, polycarboxylate sodium salt 1.25%, wetting agent sodium lauryl sulfate 1.5%, filler sucrose 25.0%, ordinary silica 2.5%, fumed silica 0.5%, anhydrous sodium sulfate supplement 100%.
[0036] The preparation method is as follows: the original drug of benomyl is pulverized to a particle size of 15-30 μm by an air-jet pulverizer; the dispersant, wetting agent and various fillers are mixed uniformly, and then pulverized to a particle size of 15-30 μm by an air-jet pulverizer; The pulverized auxiliary agent is mixed with the pulverized original drug for a second time, and the benomyl wettable powder is obtained after mixing evenly.
Embodiment 2
[0038] A benomyl wettable powder, the formula of which is (wt%): benomyl 50.0%, dispersant calcium lignosulfonate 4.5%, sodium polycarboxylate 1.5%, wetting agent sodium lauryl sulfate 2.0%, filler sucrose 25.0%, ordinary silica 2.5%, fumed silica 0.5%, and modified corn starch supplement 100%.
[0039] The preparation method is the same as in Example 1.
Embodiment 3

Abstract
The invention discloses a benomyl wettable powder and a preparation method thereof. The benomyl wettable powder comprises the following components in percentage by weight: 45-55% of benomyl, 4-10% of dispersing agent, 0.5-4.0% of wetting agent and the balance of filler. Through the optimal combination of the auxiliaries, the decomposition of the benomyl can be effectively inhibited, the bag expansion phenomenon in the storage and transportation process is solved, and the packaging cost is reduced. According to the invention, the generation of dibutylurea is reduced, and the risk of phytotoxicity is reduced. According to the invention, the quality stability is improved, the heat storage stability or the storage stability under a high-temperature condition is improved, the problems of heat storage caking, poor wet screening, reduced suspension rate and the like are solved, and the material after heat storage keeps good fluidity, high suspension rate and good fineness.
Description
technical field [0001] The invention relates to a pesticide wettable powder, in particular to a benomyl wettable powder with good stability, no agglomeration, no bag swelling and high suspension rate and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Benomyl is a systemic fungicide developed by DuPont. It has the functions of protection, treatment and eradication. It can prevent diseases caused by fungi of Ascomycetes, Deuteromycetes and some Basidiomycetes effect. At present, it has stopped being sold in the United States, but it is still used in many countries, and there are also many domestic companies registered and produced. [0003] Benomyl is easy to decompose. First, it decomposes to produce butyl isocyanate and carbendazim. The butyl isocyanate further reacts with moisture to produce carbon dioxide and butylamine. It reacts with butylamine to produce N,N'-dibutylurea (dibutylurea). N,N'-dibutylurea is a ...
