Embodiment 1

[0028] Product Example 1 2.6% yam polysaccharide · benzovinfluconazole wettable powder (1:0.3)

[0029] Yam polysaccharide 2%, benzovinfluconazole 0.6%, sodium carboxymethylcellulose 6%, alkyl naphthalene sulfonate 1%, light calcium carbonate 2%, kaolin supplement 100%.

[0030] The raw materials were weighed according to the above formula, mixed evenly, pulverized by an airflow mill, and 2.6% yam polysaccharide · benzovinfluconazole wettable powder was obtained after passing the test.

Embodiment 2

[0031] Product Example 2 5% yam polysaccharide · benzovinfluconazole granule (1:4)

[0032] Yam polysaccharide 1%, benzovinfluconazole 4%, alkyl naphthalene sulfonate 10%, starch 2%, sodium sulfate 1%, kaolin supplement 100%.

[0033] Weigh the raw materials according to the above formula ratio, mix them evenly, pulverize them, add water to moisten them, stir them evenly, and then granulate them with a screw extrusion granulator, dry and sieve to get 5% yam polysaccharide · benzovinfluconazole Granules.

Embodiment 1

[0035] 2% yam polysaccharide wettable powder: 2% yam polysaccharide, 6% sodium carboxymethyl cellulose, 1% alkyl naphthalene sulfonate, 2% light calcium carbonate, 100% kaolin supplement. The preparation method is the same as Product Example 1.

Abstract

The invention relates to a bactericidal composition containing yam polysaccharide and benzovindiflupyr. The bactericidal composition is prepared from the active components of the yam polysaccharide and the benzovindiflupyr, wherein the weight ratio of the yam polysaccharide to the benzovindiflupyr is equal to 1 to (0.3-4). The bactericidal composition is prepared by compounding the yam polysaccharide and the benzovindiflupyr according to the weight ratio of 1 to (0.3-4), thus having an obvious synergetic effect; as a synergist for the benzovindiflupyr, the yam polysaccharide can obviously improve the inhibitory activity of the benzovindiflupyr for pathogenic bacteria; after the yam polysaccharide and the benzovindiflupyr are blended together, the use amount of the benzovindiflupyr serving as a chemical agent also can be reduced, so that the cost is lowered, and the residue of the chemical agent is reduced.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicidal composition containing yam polysaccharide and benzovinfluconazole. Background technique [0002] Benzofenfluconazole (test code SYN545192) is a pyrazole amide fungicide developed by Syngenta, which belongs to the succinate dehydrogenase inhibitor. Benzofenfluconazole is mainly used in cereal crops. It has excellent control effects on major diseases of various crops such as wheat, corn and special crops. It can well control wheat leaf blight, peanut black spot, and wheat take-all And wheat base rot, especially for wheat powdery mildew, corn small spot and gray mold, and has excellent control effect against Asian soybean rust. Benzodifluconazole has no cross-resistance with methoxyacrylate and triazole fungicides, and can be used in combination with a variety of fungicides. [0003] Chinese patent 201610706540.0 discloses a fungicidal composition comprising ben...
