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 1

[0174] Example 1 10% pyraclostrobin + 10% tetrazolid wettable powder

[0175] Pyrafenafil 10%

[0176] Pyridine Tetrazolium 10%

[0177] Sodium Lauryl Sulfate 3%

[0178] Sodium lignosulfonate 5%

[0179] Kaolin topped up to 100%

[0180] The active ingredient, various additives and fillers are mixed according to the ratio of the formula, and after being pulverized by a superfine pulverizer, the wettable powder of 10% pyraclostrobin + 10% tetrazole pyridine can be obtained.

Embodiment 2

[0181] Example 2 12% pyraclostrobin + 3% tetrazole pyridine emulsifiable concentrate

[0182] Pyrafenapyramide 12%

[0183] Pyridine Tetrazolium 3%

[0184] Octylphenol Polyethylene Glycol Ether 3%

[0185] Ethoxylated Castor Oil 5%

[0186] Calcium dodecylbenzenesulfonate 3%

[0187] N-methylpyrrolidone topped up to 100%

[0188] Prepare the above-mentioned ingredients according to the proportion, and stir evenly to obtain a homogeneous phase.

Embodiment 3

[0189] Example 3 10% pyraclostrobin + 20% tetrazole pyridine water dispersible granules

[0190] Pyrafenafil 10%

[0191] Pyridine Tetrazolium 20%

[0192] Modified Calcium Lignosulfonate 5%

[0193] Sodium Lauryl Sulfate 5%

[0194] Urea 1%

[0195] Modified attapulgite topped up to 100%

[0196] Mix the active ingredients of pyraclofen, pyrazole tetrazole, 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 Pressed material. After drying and sieving, 10% pyraclostrobin + 20% tetrazolid water-dispersible granules were obtained.

Abstract

The invention provides a bactericidal composition. The bactericidal composition comprises the following active components: isopyrazam and picarbutrazox in a weight ratio of 50: 1 to 1: 50. The invention also 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 relatesto the application 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 alsorelates 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...
