Embodiment l

[0030] Embodiment 1 total content is 20% propineb and cymoxanil water dispersible granules

[0031]Weigh the raw material components (by mass percentage): propineb 10%, cymoxanil 10%, hydroxyene adenine 0.007%, adenine adenine 0.001%, wetting agent T1004 2%, dispersant T2020 4%, T2700 3%, disintegrant ammonium sulfate 5%, defoamer DF-1587 0.4%, filler kaolin to make up. Mix the above-mentioned raw material components, stir them evenly, and get the mother powder with a particle size of 800 mesh or more through airflow pulverization, then add an aqueous solution containing 0.5% binder polyethylene glycol, fully mix with a mixing mixer, and extrude to granulate Machine granulation, and finally dried by a dryer to obtain a water-dispersible granule compounded with 10% propineb and 10% cymoxanil. After inspection, the content of propineb is 10.3%, the suspension rate of propineb is 85%, the content of cymoxanil is 10.4%, the suspension rate of cymoxanil is 82%, the moisture conten...

Embodiment 2

[0032] Example 2 The total content is 30% propineb and cymoxanil water dispersible granules

[0033] Weigh the raw material components (by mass percentage): propineb 15%, cymoxanil 15%, hydroxyene adenine 0.007%, adenine adenine 0.001%, wetting agent KDS95 2%, dispersant WLNOK 4%, T2700 3%, disintegrant ammonium sulfate 3%, filler kaolin to make up. Mix the above-mentioned raw material components, stir them evenly, and get the mother powder with a particle size of more than 800 mesh through jet crushing, then add an aqueous solution containing 0.5% binder polyethylene glycol, fully mix with a mixing mixer, and use a granulator to make Granules, and finally dried by a dryer to obtain a water-dispersible granule compounded with 15% propineb and 15% cymoxanil. After inspection, the content of propineb is 15.2%, the suspension rate of propineb is 85%, the content of cymoxanil is 15.1%, the suspension rate of cymoxanil is 87%, the moisture content is ≤2.0%, the pH value is 6.8...

Embodiment 3

[0034] Example 3 The total content is 40% propineb and cymoxanil water dispersible granules

[0035] Weigh raw material components (by mass percentage): 20% propenebine, 20% cymoxanil, 0.007% hydroxyadenine, 0.001% aryl adenine, 2% wetting agent SXC, 4% dispersing agent WG4, WG5 3%, disintegrant ammonium sulfate 6%, defoamer DF-66 0.8%, filler diatomaceous earth. Mix the above-mentioned raw material components, stir them evenly, and then pulverize them by air flow to obtain mother powder with a particle size of 800 mesh or more, then add the aqueous binder solution, mix thoroughly with a mixing mixer, granulate with a granulator, and finally dry with a dryer , to obtain 20% propineb and 20% cymoxanil compounded water dispersible granules. After inspection, the content of propineb is 20.3%, the suspension rate of propineb is 90%, the content of cymoxanil is 20.1%, the suspension rate of cymoxanil is 82%, the moisture content is ≤2.0%, the pH value is 7.0, and the persisten...

Abstract

The invention discloses a formula and a preparation method of water dispersible granules containing propineb and cymoxanil. The water dispersible granules comprise the following components in percentage by mass: 5-70% of propineb, 5-70% of cymoxanil, 0.001-0.01% of oxyenadenine, 0.001-0.01% of enadenine, 1-5% of a wetting agent, 2-15% of a dispersant, 1-20% of a disintegrating agent, 0-5% of an adhesive, 0-3% of a defoamer and the balance of a carrier. The water dispersible granules disclosed by the invention have a remarkable effect on soil-borne diseases such as cucumber downy mildew, grape downy mildew, pepper phytophthora blight, potato blight, watermelon fusarium wilt and the like and meanwhile further have the advantages of being environment-friendly, low in toxicity, strong in effect, growth-promoting, fast to disintegrate and the like.

Description

technical field [0001] The invention relates to a fungicide, in particular to a formulation of water-dispersible granules containing propineb and cymoxanil and a preparation method thereof. Background technique [0002] Propineb and cymoxanil are very characteristic fungicides. Propineb acts on fungal cell wall and protein synthesis, can inhibit the infection and germination of spores, and at the same time inhibit the growth of mycelia, leading to its deformation and death. It is an excellent plant protection agent. In the case of high content It has a certain therapeutic effect, and zinc ions also have a good preventive effect on bacterial and viral diseases. Cymoxanil can prevent the germination of pathogenic bacteria spores, and is also lethal to pathogenic bacteria that invade the host. It is an efficient systemic therapeutic agent. The combination of the two, combining protection and treatment, can quickly and efficiently protect against downy mildew and blight of oo...
