Embodiment 1

[0055] Example 1: Indoor Toxicity Determination of Fluoramide and Metrafenone Complex to Cucumber Powdery Mildew

[0056] The test chemicals were all provided by Shandong Weifang Runfeng Chemical Co., Ltd.

[0057] Experimental design: After the effective inhibitory concentration range of each agent is determined by preliminary test, a series of concentration treatments are set for each agent according to the content of active ingredients, and water control is set. Refer to the "Pesticide Indoor Bioassay Test Guidelines for Fungicides", and use the pot method to determine the EC of pesticides and mixtures. 50 , and calculate its co-toxicity coefficient with the method of calculating joint virulence proposed by Sun Yunpei et al. (1960).

[0058] The calculation formula is as follows (with metrafenone as the standard drug, its toxicity index is 100):

[0059]

[0060]

[0061] M's Theoretical Toxicity Index (TTI) = Fluoramide TI × P 氟酰胺 + Metrafenone TI×P 苯菌酮 ;

Embodiment 2

[0073] Embodiment 2: 20% Fluoramide Metrafenone Suspension Concentrate

[0074]The formula is: 10% of the active ingredients of the drug fluoramide, 10% of metrafenone, 2% of the dispersant SOPROPHOR SC, 2% of Geropon T / 36, 1% of the wetting agent PE6400, 2% of NP-10, and the thickener of xanthan gum 0.5%, defoamer silicone oil 0.5%, antifreeze propylene glycol 6%, preservative Cathone 0.1%, water make up 100%.

[0075] Preparation method: high-speed shear the dispersant, wetting agent, defoamer, preservative and water in the above formula, mix evenly, then add fluoramide and metrafenone, and perform sand grinding in a sand mill. During the grinding period, the particle size of the material needs to be checked frequently, and the particle size is sanded to 3-5μm; the thickener is added to the antifreeze and mixed evenly, and then the mixture of the thickener and antifreeze is added to the liquid after sanding The mixture is homogeneously mixed by high-speed shearing to prepar...

Embodiment 3

[0076] Embodiment 3: 50% Fluoramide Metrafenone Suspension Concentrate

[0077] The formula is: 33.3% of the active ingredients of the drug fluoramide, 16.7% of metrafenone, 3% of the dispersant SOPROPHOR SC, 1% of Geropon T / 36, 0.6% of the wetting agent PE6400, 2.4% of NP-10, and the thickener of xanthan gum 0.5%, defoamer silicone oil 0.5%, antifreeze propylene glycol 6%, preservative Cathone 0.1%, water make up 100%.

[0078] The preparation method is the same as in Example 1.

Abstract

The invention belongs to the technical field of pesticides, and discloses a bactericidal composition containing metrafenone and fluxapyroxad and application thereof. The bactericidal composition is prepared by compounding active pharmaceutical ingredients of fluxapyroxad and metrafenone according to a specific ratio and has a good synergistic effect, and the mass ratio of fluxapyroxad to metrafenone is preferably (1-8): 1 and more preferably (1-5): 1. According to the bactericidal composition, the bactericidal spectrum is expanded, the lasting period of the drug is prolonged, the generation ofdrug resistance is delayed, and the bactericidal composition has a very good effect of preventing and treating powdery mildew, southern blight, black scurf and other diseases in grain crops, vegetables and fruit trees, and is beneficial to sustainable development of the environment. In addition, the preparation process of the composition is environmentally friendly, and safety and pollution problems are avoided.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a bactericidal composition, in particular to a bactericidal composition containing metrafenone and fluoroamide and the application of the composition in preventing and treating diseases of food crops, vegetables or fruit trees. Background technique [0002] Among the diseases of food crops, vegetables, fruits and other plants, powdery mildew often causes serious impact due to its characteristics of rapid development and difficulty in eradication. In order to effectively prevent and control various plant diseases, chemical agents are usually used in the agricultural production process. Among the pesticides used against powdery mildew and other diseases, Metrafenone belongs to the benzophenone fungicides, which mainly inhibits the spore germination of powdery mildew bacteria by interfering with the development and formation of appressoria during spore germination of pathogenic bact...
