Problems solved by technology

Fungicides containing a single active ingredient often have certain defects in the prevention and control of agricultural diseases. Continuous repeated use not only makes pathogenic bacteria prone to drug resistance, but also easily causes pollution to food and the environment. Reasonable mixing of active ingredients in fungicides able to overcome the above disadvantages

Embodiment 111

[0173] Example 1 11.2% pyraclofen + 10% fluopyram wettable powder

[0174] Pyrafenafil 11.2%

[0175] Fluopyram 10%

[0176] Sodium Lauryl Sulfate 3%

[0177] Sodium lignosulfonate 5%

[0178] Kaolin topped up to 100%

[0179] The active ingredients, various additives and fillers are mixed according to the proportion of the formula, and after being pulverized by an ultrafine pulverizer, 11.2% pyraclofen + 10% fluopyram wettable powder can be obtained.

Embodiment 2

[0180] Example 2 12% pyraclofen + 6% fluopyram EC

[0181] Pyrafenapyramide 12%

[0182] Fluopyram 6%

[0183] Octylphenol Polyethylene Glycol Ether 3%

[0184] Ethoxylated Castor Oil 5%

[0185] Calcium dodecylbenzenesulfonate 3%

[0186] N-methylpyrrolidone topped up to 100%

[0187] Prepare the above-mentioned ingredients according to the proportion, and stir evenly to obtain a homogeneous phase.

Embodiment 3

[0188] Example 3 20% pyraclofen + 20% fluopyram water dispersible granules

[0189] Pyrafenafil 20%

[0190] Fluopyram 20%

[0191] Modified Calcium Lignosulfonate 5%

[0192] Sodium Lauryl Sulfate 5%

[0193] Urea 1%

[0194] Modified attapulgite topped up to 100%

[0195] Mix pyraclofen, fluopyram active ingredient, dispersant, wetting agent, disintegrating agent and filler according to the proportion of the formula, and then crush it into a wettable powder by airflow; then add a certain amount of water to mix and extrude Materials. After drying and sieving, 20% pyraclostrobin + 20% fluopyram water-dispersible granules were obtained.

Abstract

The invention provides a bactericidal composition. The bactericidal composition comprises the following active components: isopyrazam and fluopicolide in a weight ratio of 50: 1 to 1: 50. The invention relates to the application of the bactericidal composition to controlling harmful fungi and bacteria on cereals, vegetables, fruits, ornamental plants and vines. The invention further relates to theapplication of the bactericidal composition to to-be-controlled sites for preventing and treating pathogenic or saprophytic fungi and bacteria in soil or cultivation mediums. The invention also relates to the application of the bactericidal composition to treatment of seeds to protect the seeds from invasion by carried phytopathogens.

Description

technical field [0001] The present invention relates to a bactericidal composition; the present invention also relates to the application of the bactericidal composition in controlling or preventing plant pathogenic fungi from infesting plants in the field of agriculture or gardening. Background technique [0002] At present, for the prevention and control of diseases that are prone to resistance in agriculture, it is the best choice to use pesticide varieties with different action mechanisms for mixing. The effect of a single dose. Fungicides containing a single active ingredient often have certain defects in the prevention and control of agricultural diseases. Continuous repeated use not only makes pathogenic bacteria prone to drug resistance, but also easily causes pollution to food and the environment. Reasonable mixing of active ingredients in fungicides The above disadvantages can be overcome. The synergistic effect of the active ingredients through reasonable compou...
