Embodiment 1

[0023] Embodiment 1 water dispersible granule

[0024] This embodiment is a water-dispersible granule containing 25% polyoxin-sclerotinia net active ingredient, and the formula is as follows:

[0025] Polyoxin 10g, Sclerotin 15g, Sodium Lauryl Sulfate 2g, Polyethylene Glycol 1g, Lignosulfonate 2g, Polyoxymethylene Sulfonate Condensate (NNO) 2g, Sodium Carboxymethylcellulose 1g , starch paste 0.5g, polyoxyethylene lauryl ether 1g, make up to 100g with kaolin.

[0026] The active ingredient polyoxin and sclerotinia, the additives sodium lauryl sulfate and polyethylene glycol, the carrier sulfonic acid polyformaldehyde condensate and tea Ku are mixed, stirred evenly, and pulverized to obtain the mother powder. Mix the mother powder with the binder sodium carboxymethylcellulose and polyoxyethylene lauryl ether evenly, then granulate, dry, and sieve to obtain 25% polyamycin·sclerotia water-purifying dispersible granules .

Embodiment 2

[0028] The difference between the present embodiment and embodiment 1 is only that the formula is as follows:

[0029] Polyoxamycin 5g, polyoxamycin 25g, sodium lauryl sulfate 1g, polyethylene glycol 2g, lignosulfonate 1g, sulfonic acid polyoxymethylene condensate (NNO) 1 part, carboxymethyl cellulose 0.5 g of sodium, 1 g of ammonium sulfate, 0.5 g of polyoxyethylene lauryl ether, and 100 g of kaolin were added to prepare 25% polyamycin-sclerotinia water-purifying dispersible granules.

Embodiment 3

[0031] The difference between the present embodiment and embodiment 1 is only that the formula is as follows:

[0032] Polyoxin 8g, Sclerotin 22g, Sodium Lauryl Sulfate 1.5g, Polyethylene Glycol 3g, Lignosulfonate 3g, Polyoxymethylene Sulfonate Condensate (NNO) 3g, Sodium Carboxymethylcellulose 0.8g, ammonium sulfate 0.7g, lauryl polyoxyethylene ether 0.6g, then make up to 100g with kaolin.

Abstract

The invention provides a bactericidal composition for alternaria alternata of tobaccos and application thereof. The effective active ingredients of the bactericidal composition are polyoxins and dimethachlon, the net weight ratio of the polyoxins to the dimethachlon is 5-10 to 15-25. The bactericidal composition has the remarkable prevention and control effect on the alternaria alternata of tobaccos, a low-dosage bactericidal effect is good and is better than that of high-content bactericidal composition, and the costs of drugs can be reduced.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a fungicidal composition for tobacco red spot disease and its application. Background technique [0002] Tobacco red spot disease is a major disease in tobacco production, commonly known as "red spot", and it is one of the major diseases in tobacco production in my country. The disease occurs in every tobacco-producing area in my country, especially in Heilongjiang, Jilin and other places. Leaf infection mostly occurs from the lower leaves and gradually develops upwards. Lesions are small yellowish-brown spots at first, and later develop into brown round or nearly round spots with reddish brown or dark brown concentric ring patterns. When the expansion is fast, a yellow halo appears on the edge. When the humidity is high, a dark brown or black mold layer can be seen on the spots. Lesions are brittle and easily broken. In severe cases, the lesions merge and the leaves become broken ...
