Embodiment 1

[0019] Embodiment 1: 20% Shenzimycin Brothalinil wettable powder

[0020] Add 10 g of Shenazimycin, 10 g of Bromothalonil, 12 g of Sodium Lignosulfonate, 6 g of Sodium Methylenebis-Naphthalene Sulfonate, and white carbon black to 100 g, and the mixture is jet-milled to obtain a wettable powder.

Embodiment 2

[0021] Embodiment 2: 20% Shenzimycin Brothalinil aqueous suspension

[0022] With 15g of Shenzimycin, 5g of bromothalinil, 4g of phenethylphenol formaldehyde resin polyoxyethylene ether, 5g of base phenol formaldehyde resin polyoxyethylene ether, 3g of ethylene glycol, 5.5g of fatty alcohol polyoxyethylene ether, 1g of xanthan gum, supplemented with 100g of water, mixed, and homogenized by wet grinding to obtain a water suspension.

Embodiment 3

[0023] Embodiment 3: 25% Shenzimycin Brothalinil Aqueous Suspension Concentrate

[0024] Add 5g of Shenzimycin, 20g of Bromothalonil, 8g of Fatty Alcohol Polyoxyethyl Ether, 4g of Nonylphenol Polyoxyethylene Ether, 2g of Starch, 3g of Sodium Bicarbonate, 10g of Bentonite and Kaolin to 100, mix and pulverize Granulation produces water-dispersible granules.

[0025] Bioactivity assay

[0026] The inventor has found that the combination of Shenzimycin and bromoxynil has a significant synergistic effect on anthracnose through a large number of screening tests, not just the simple addition of the two medicaments, which can be seen from the following biological assay examples clearly see.

Abstract

The invention discloses a bactericidal composition for diseases of melons, which is characterized in that: it is compounded by the active ingredients of shenzimycin and bromothalonil, and the weight ratio of shenazimycin to bromothalonil is 1:70‑70:1.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition for diseases of melons. Background technique [0002] In the process of agricultural production, in order to reduce the losses caused by fungal diseases, chemical control is one of the more significant means at present. The currently used medicaments produce different degrees of resistance, and it is reported that due to this unscientific drug use method, the resistance generation time of various medicaments is shortened year by year, resulting in a substantial increase in control costs, environmental costs, and pharmacy research and development costs. Based on this current situation, it is more economical and effective to solve the above problems to improve the drug effect on the existing basis. [0003] Shenzimycin is an antibiotic secreted by Pseudomonas fluorescens through biological culture, and has dual functions of broad-spectrum ...
