[0066] Prepare a total of 100 kg of 30% ebuazole water suspension concentrate, and weigh ebuazole, wetting and dispersing agent, thickener, antifreeze, defoamer, and water respectively according to the formula shown in Table 7. Mix ecloazole, wetting and dispersing agent, antifreeze, thickener and water in a high-speed mixer for 50 minutes, and then pump the mixed slurry into three sanding machines connected in sequence with a quantitative diaphragm pump for three-stage grinding. Grind, then add defoamer, make up the weight to 100kg with water, and mix well.
[0067] After testing, the 30% ebuazole water suspension concentrate prepared in this example met the specifications.
[0071] Using the same preparation process as in Example 1, 100kg of 30% ebuconazole aqueous suspension was obtained.
[0072] After testing, the 30% ebuazole water suspension concentrate prepared in this example met the specifications.

Abstract
The invention discloses suspension concentrate containing 30% of bismerthiazol. The suspension concentrate containing 30% of bismerthiazol comprises the bismerthiazol, a moistening dispersing agent, a thickening agent, an anti-freezing agent and a defoaming agent. A formula includes, by weight, bismerthiazol 30%, moistening dispersing agent 5-10%, thickening agent 1-2%, anti-freezing agent 3-8%, organic silicon defoamer SAG630 0.5-1% and the balance water. A preferable formula includes, bismerthiazol 30%, moistening dispersing agent 8%, thickening agent 1.05%, anti-freezing agent 4%, organic silicon defoamer SAG630 0.5-1% and the balance water. The moistening dispersing agent consists of alkyl naphthalene moistening agent 1004, acrylic acid graft copolymer 2500 and calcium lignosulphonate dispersing agent SA according to the weight proportion of 1:1:2, the thickening agent consists of aluminium-magnesium silicate SF-40 and xanthan gum according to the weight proportion of 20:1, and the anti-freezing agent is glycerol. The invention further discloses a preparation method of the suspension concentrate containing 30% of bismerthiazol. Compared with wettable powder containing 20% of bismerthiazol and wettable powder containing 25% of bismerthiazol, the suspension concentrate containing 30% of bismerthiazol has the advantages of being high in efficacy, environment-friendly, convenient to prepare and the like.
Description
technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a new dosage form of ebuazole and a preparation method thereof. Background technique [0002] Yebuazole, also known as cycumazole, chemical name: N.N'-methylene-bis(2-amino-5-thio-1,3,4-cumazole), soluble in dimethylformamide , dimethylsulfite, pyridine, ethanol, methanol and other organic solvents, hardly soluble in water; it is a low-toxicity fungicide, and has a good control effect on rice bacterial blight, bacterial streak disease, and citrus canker. [0003] At present, most of the ecloazole products produced and sold on the market are 20% or 25% wettable powders, which are dust-polluted when used, and are prone to long wetting time, unstable after dispersion in water, and long-term precipitation, causing poor spraying. Uniformity, resulting in excessive local concentration of crops, easy to cause phytotoxicity. [0004] Water-suspension concentrate is a viscous and f...
