Embodiment 1

[0020] Example 1 80% Zinc water dispersible granules

[0021] Weighing 81% of substituted Senzinc original powder, wetting agent sodium dodecylbenzene sulfonate 3%, dispersing agent sodium lignosulfonate 6%, disintegrating agent ammonium sulfate 2%, diluent light calcium carbonate 5%, Mix it according to the general method, after stirring evenly, pulverize it by a jet mill to obtain the master powder, mix the master powder with 3% of the binder modified sodium polyacrylate 80, then granulate, dry, and sieve to obtain about 96%. % 80% Zinc Desen in water dispersible granules. After inspection, the active ingredient content is 80.8%, the moisture content is 2.1%, the sieving (passing through a 75μm sieve) is 98.3%, the suspension rate is 80%, the persistent foaming (1min) is 10mL, the wettability is less than or equal to 1min, and the accelerated heat storage stability is qualified. In the implementation, the dosage for preventing and controlling peanut leaf spot is 800 times, ...

Embodiment 2

[0022] Example 2 70% Zinc water dispersible granules

[0023] Weigh 71% of substituted Senzinc powder, 3% of wetting agent alkyl sulfonate, 6% of dispersant polycarboxylate, 6% of disintegrant silica, and 10% of diluent diatomaceous earth. After mixing it evenly, it is pulverized by a jet mill to obtain the master powder, and the master powder is mixed with 4% polyethylene glycol No. 72 binder, and then granulated, dried, and sieved to obtain about 96% of 70%. Zinc water dispersible granules. After inspection, the active ingredient content is 70.7%, the moisture content is 1.9%, the sieving (passing through a 75μm sieve) is 98.9%, the suspension rate is 83%, the persistent foaming (1min) is 8mL, the wettability is less than or equal to 1min, and the accelerated heat storage stability is qualified. The dosage for preventing and controlling peanut leaf spot is 600, and the control effect is 81-90%.

Embodiment 3

[0024] Example 3 65% Zinc Water Dispersible Granules

[0025] Weighing 66% substituted Senzinc powder, wetting agent sodium alkyl sulfate 3%, dispersing agent alkylphenol polyoxyethylene ether formaldehyde condensate sodium sulfate 6%, disintegrating agent attapulgite 8%, diluent kaolin 5% , light calcium carbonate 6%, after mixing it evenly, pulverize it with a jet mill to obtain master powder, mix the master powder with 6% denatured polyvinyl alcohol No. 3 binder, then granulate, dry, pass Sieve about 97% of 65% Zinc Desen in water dispersible granules. After inspection, the active ingredient content is 65.7%, the moisture content is 1.6%, the sieving (passing through a 75μm sieve) is 99.1%, the suspension rate is 85%, the persistent foaming (1min) 9mL, the wettability ≤1min, and the accelerated heat storage stability is qualified. The dosage for preventing and controlling peanut leaf spot is 500 times, and the control effect is 78-96%.

Abstract

A water-dispersing particle of zineb is prepared from zineb (40-80 Wt%), wetting agent, disperser, disintegrant, diluent and adhesive through proportional mixing stirring, pulverizing, adding deionized water, stirring, granulating, drying and sieving.

Description

technical field [0001] The invention relates to an agricultural fungicide, in particular to a water-dispersible granule of Zinc Dysen. Background technique [0002] At present, there are many agricultural fungicides, and Zinc Desen is one of them. Zinc (English common name: zineb, chemical formula C 4 H 6 N 2 S 4 Zn) is a protective agent for foliar spraying, which has strong contact killing effect on many pathogens such as downy mildew, late blight and anthracnose. Safe for plants, the active ingredients are chemically active, and are easily oxidized into isothiocyanate compounds in water. It has a strong inhibitory effect on enzymes containing -SH groups in pathogenic bacteria, and can directly kill pathogen spores and inhibit spore germination. Prevent pathogens from invading plants, but have little killing effect on pathogenic mycelium that has invaded plants. Therefore, the use of dysenzine to prevent and control diseases should be carried out at the beginning of ...
