Problems solved by technology

[0011] However, in practical applications, long-term single application of an active compound to control diseases will lead to the development of disease resistance, resulting in a decrease in the control effect of the compound, or even a complete loss of control effect.

specific Embodiment approach

[0156] The present invention will be further described below in conjunction with embodiment:

Embodiment 1

[0158] Example 1 2% Bacoud + 10% Pyrimethanil WP

[0159] Bacardi 2%

[0160] Pyrimethanil 10%

[0161] Sodium Lauryl Sulfate 10%

[0162] Sodium lignosulfonate 5%

[0163] Silica 10%

[0164] Kaolin supplemented to 100%

[0165] The active compound, various additives and fillers are mixed according to the proportion of the formula, and after being pulverized by an ultra-fine pulverizer, 2% Bacoud + 10% pyrimethanil wettable powder can be obtained.

Embodiment 2

[0166] Example 2 50% Bacan + 1% pyrimethanil wettable powder

[0167] Bacardi 50%

[0168] Pyrimethanil 1%

[0169] Calcium dodecylbenzenesulfonate 1%

[0170] Sodium lignosulfonate 2%

[0171] Sucrose make up to 100%

[0172] The active compound, various additives and fillers are mixed according to the proportion of the formula, and after being pulverized by an ultrafine pulverizer, 50% Bacaride + 1% pyrimethanil wettable powder can be obtained.

Abstract

The invention relates to a fungicidal composition and also relates to a method for controlling plant diseases. The fungicidal composition provided by the invention comprises active ingredients including bellkute and pyrimethanil, wherein a weight ratio of bellkute to pyrimethanil is 100:1-1:100, and a synergetic effect is achieved. The content of the active ingredients including bellkute and pyrimethanil accounts for 5-60 percent of that of the composition. Bellkute and pyrimethanil are subjected to binary compounding, have different action mechanisms and do not have cross resistance, the fungicidal spectrum can be widened after the ingredients are mixed, a good control effect is achieved, resistance of pathogenic bacteria is delayed, and the fungicidal composition is safe to multiple crops. The fungicidal composition can be used for controlling fungi on grains, fruits, vegetables, cotton, fruit trees and ornamental plants.

Description

technical field [0001] The present invention relates to a fungicidal composition, and also relates to a method for preventing and controlling plant diseases. Background technique [0002] Due to the harm of various plant pathogenic bacteria, many crops have caused huge losses. The light ones reduce production, and the severe ones can lead to production failure, which directly affects the economic interests of farmers. Therefore, farmers are forced to use fungicides to prevent and control diseases. [0003] A variety of fungal diseases often occur on agricultural crops (cereals, fruits, vegetables, flowers), such as gray mold, powdery mildew, sclerotinia, stem blight, creeping blight, anthracnose, ring spot, black Star disease, leaf spot, spot defoliation, fruit soft rot, penicillium, green mold, rust, peach brown rot, smut, streak etc. [0004] Bellkute, also known as biguanide trioctylbenzenesulfonate, its chemical name is: 1'1-imino (octylmethylene) biguanide 3 (alkylphen...
