Embodiment 1

[0019] Example 1: 18% biguanide trioctyl benzene sulfonate · penthiastrobin wettable powder

[0020] Add 9g of biguanide trioctylbenzenesulfonate, 9g of benzathystrobin, 13g of sodium dodecylbenzenesulfonate, 6g of sodium methylene bis-naphthalenesulfonate, 3g of wetting and penetrating agent F, and white carbon black to 100 g, the mixture was jet milled to obtain a wettable powder.

Embodiment 2

[0021] Example 2: 25% biguanide trioctyl benzene sulfonate · penthiastrobin aqueous suspension

[0022] Biguanide trioctylbenzene sulfonate 5g, penthiastrobin 20g, naphthalenesulfonic acid formaldehyde condensate sodium salt 5g, phenol formaldehyde resin polyoxyethylene ether 2g, glycerin 3g, silicone oil 0.5g, fatty alcohol 5.5 g of polyoxyethyl ether, 1 g of xanthan gum, 2 g of bentonite, and 100 g of water, mixed, and homogenized by wet grinding to obtain an aqueous suspension.

Embodiment 3

[0023] Example 3: 30% Biguanide Trioctylbenzenesulfonate · Penthiastrobin Water-dispersible Granules

[0024] Add 20g of biguanide trioctylbenzenesulfonate, 10g of pentothiastrobin, 6g of calcium salt of alkylbenzenesulfonate, 6g of nonylphenol polyoxyethylene ether, 2g of urea, 3g of sodium bicarbonate, 12g of bentonite, and kaolin to 100, mixed, crushed and granulated to prepare water-dispersible granules.

[0025] Bioactivity assay

[0026] Through a large number of screening tests, the inventors found that the combination of biguanide trioctylbenzenesulfonate and benzathystrobin has a significant synergistic effect on rice sheath blight, not just the simple addition of the two agents , which is clear from the following bioassay examples.

Abstract

The invention discloses a bactericidal composition containing iminoctadine tris and benzothiostrobin. The bactericidal composition is characterized by being formed by compounding active ingredient iminoctadine tris and benzothiostrobin, and the weight ratio of iminoctadine tris to benzothiostrobin is (1:60):(60:1). The combination of the two fungicides for use expands the fungicide spectrum, and various diseases can be prevented and controlled; the bactericidal composition has a significant synergistic effect on rice sheath blight disease; the bactericidal composition is safe to target crops,humans and livestock and the environment; the pesticide application amount is reduced, the number of pesticide application times is reduced, and the bactericidal composition facilitates use, reduces use cost and has the advantages of high efficiency, quick effect and long-lasting effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition containing biguanide trioctylbenzene sulfonate and fenthiastrobin. 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] Benzotystrobin has a broad-spectrum fungicidal activity. In addition to good control effect...
