Embodiment 1

[0021] 40% Trisulfuron-methyl water-dispersible granules. Take by weighing 40% of tribenuron-methyl original drug, 3.0% of wetting agent alkyl naphthalene sulfonate, 6% of dispersing agent sodium lignosulfonate, 10% of disintegrating agent ammonium sulfate, 2% of binder polyethylene glycol, It is mixed according to the general method, and after being evenly stirred, it is pulverized by a jet mill to obtain mother powder, then granulated, dried, and sieved to obtain about 40% tribenuron-methyl water-dispersible granules. After inspection, the active ingredient content is 40.3%, the moisture content is 1.9%, the sieving (passing through a 75um sieve) is 98%, the suspension rate is 92%, the persistent foaming property (1min) is 10mL, the wettability is ≤1min, and the accelerated thermal storage stability is qualified.

Embodiment 2

[0023] 50% Trisulfuron-methyl water-dispersible granules. Weigh 50% of tribenuron-methyl original drug, 3.0% of wetting agent sodium dodecylbenzene sulfonate, 7% of dispersant sodium lignosulfonate, 5% of disintegrating agent sodium sulfate, binder carboxymethyl cellulose 1%, mixed it according to the general method, after stirring evenly, pulverized by jet mill to obtain mother powder, then granulated, dried, and sieved to obtain about 50% tribenuron-methyl water-dispersible granules. After inspection, the active ingredient content is 50.5%, the moisture content is 2.0%, the sieving (passing through a 75um sieve) is 97.9%, the suspension rate is 90%, the persistent foaming property (1min) is 8mL, the wettability is ≤1min, and the accelerated thermal storage stability is qualified.

Embodiment 3

[0025] 60% Trisulfuron-methyl water-dispersible granules. Weigh 60% of tribenuron-methyl original drug, wetting agent sodium alkyl phosphate 3.0%, dispersant alkylphenol polyoxyethylene ether formaldehyde condensate sodium sulfate 6%, disintegrant sodium sulfate 5%, binder carboxymethyl Base cellulose 1%, mix it according to the general method, after stirring evenly, pulverize through a jet mill to obtain mother powder, then granulate, dry, and sieve to obtain about 60% tribenuron-methyl water-dispersible granules. After inspection, the active ingredient content is 60.1%, the moisture content is 2.2%, the sieving (passing through a 75um sieve) is 96%, the suspension rate is 89%, the persistent foaming property (1min) is 10mL, the wettability is ≤1min, and the accelerated thermal storage stability is qualified.

Abstract

The invention relates to a tribenuron-methyl water dispersible granule and a method for preparing the same, belonging to the field of the agrochemical herbicide. The tribenuron-methyl water dispersible granule is regular or irregular in shape and contains 40-80 weight percent of tribenuron-methyl. The method for preparing the tribenuron-methyl water dispersible granule comprises the following steps: a certain proportion of wetting agent, dispersing agent, disintegrating agent, binding agent and carrier are added to the raw tribenuron-methyl, mixed with the tribenuron-methyl and stirred uniformly to the tribenuron-methyl; the mixture is pulverized to obtain mother powder; a certain proportion of deionized water is added to the mother powder and mixed with the same; the mother powder mixed by the deionized water is granulated; and the tribenuron-methyl water dispersible granule is prepared after being dried and screened. The tribenuron-methyl water dispersible granule overcomes the defect of the wettable powder and reduces the use cost of the peasant and the pollution to the environment when being processed and used. With agents of different components being added to the tribenuron-methyl water dispersible granule, the tribenuron-methyl water dispersible granule has the characteristics of high content of active components, rapid disintegrating speed, good dispersing property, stable thermal storage performance, high fungicidal effectiveness and safety during use, and the like.

Description

technical field [0001] The invention relates to an agricultural fungicide, in particular to a tribenuron-methyl water-dispersible granule and a preparation method thereof. Background technique [0002] Tribenuron-methyl, chemical name: 2-[4-methoxy-6-methyl-1,3,5-triazin-2-yl(methyl)aminomethylamidosulfonyl] Benzoic acid or methyl ester. Stability: stable at 45°C, no obvious photodecomposition under field conditions; stable at pH 8-10 when hydrolyzed at 45°C, but rapidly decomposed at pH<7 or pH>; DT501-7 days in soil. [0003] Mode of action: It belongs to the selective systemic conduction type sulfonylurea herbicide and is an inhibitor of side chain amino acid biosynthesis. Broad-leaved weeds are transferred to the body after being absorbed by leaves and roots, inhibit the synthesis of acetolactase, cannot synthesize valine and isoleucine, prevent cell division, inhibit the growth of shoots and roots, and are sensitive to broad-leaved weeds. Weeds die within 14 da...
