Embodiment 1
[0030] Weigh 10% syringstrobin, 25% prochloraz, 5% TERSPERSE 4894 (produced by Huntsman, USA), 2% TERSPERSE 2500 (produced by Huntsman, USA), 1% TERSPERSE 2020 (produced by Huntsman, USA) produced), 0.2% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% siliconedefoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), deionized water to 100% by weight share. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 35% syringstrobin-prochloraz suspension.
[0031] In this embodiment, the weight ratio of syringstrobin and prochloraz can vary from 1:20 to 5:1, and the total weight content of the two is still 35%, forming a new embodiment.
Embodiment 2
[0033] Weigh 20% syringstrobin, 20% prochloraz, 2% TERSPERSE 2020, 3% Span-60#, 4% Tween-60#, 1% TERSPERSE 2500, 0.5% white carbon black, 0.3% xanthan Glue, 5% ethylene glycol, 0.5% benzoic acid, 0.5% siliconedefoamer, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 40% syringstrobin prochloraz suspension.
[0034] In this embodiment, the weight ratio of syringstrobin and prochloraz can vary from 1:20 to 5:1, and the total weight content of the two is still 40%, forming a new embodiment.
Embodiment 3
[0036] Weigh 24% syringstrobin, 12% prochloraz, 1%TERSPERSE 2020, 3% agricultural milk 1601#, 3% agricultural milk 2201#, 1%TERSPERSE 2500, 0.3% xanthan gum, 5% ethylene glycol, 0.5% formaldehyde, 0.5% siliconedefoamer, and deionized water are added to 100% by weight. High-speed shearing and dispersion for 30 minutes, and sand grinding with a sand mill to prepare 36% syringstrobin-prochloraz suspension.
[0037] In this embodiment, the weight ratio of syringstrobin and prochloraz can be varied between 1:20 and 5:1, and the total weight content of the two is still 36%, forming a new embodiment.

Abstract
The invention discloses a bactericidal composition containing coumoxystrobin and prochloraz. The weight ratio of the coumoxystrobin to the prochloraz or salt thereof is 1:20-5:1. The composition can be prepared into agriculturally permissible formulations such as a suspending agent, emulsion in water, microemulsion, missible oil and wettable powder. The bactericidal composition has reasonable components and a good sterilization effect, the cost of pesticide consumption is low, and the activity and the sterilization effect of the bactericidal composition are higher than simply superposed activities of various components; compared with the conventional single preparations, the invention has the advantages that: the bactericidal composition has a remarkable synergistic effect besides a remarkable sterilization effect, can delay the generation of the resistance, does not pollute crops, is high in safety, and meets safety requirements of pesticide preparations, and a residual amount is small; and the bactericidal composition has remarkable effects of controlling diseases of fruit trees, vegetable anthracnose, rice blast and banded sclerotial blight.
Description
technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing syringstrobin and prochloraz, and belongs to the technical field of compound pesticides. Background technique [0002] Methoxyacrylate fungicides are newly developed varieties of fungicides in recent years, and are a major milestone in the field of fungicides. Methoxyacrylate fungicides have a unique mechanism of action, which prevents ATP synthesis in cells by locking the electron transfer between cytochrome b and c1, thereby inhibiting mitochondrial respiration and exerting antibacterial effects. Effective against strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles. It has protection, treatment, eradication, penetration and systemic activities, and can degrade quickly in plants, soil and water. Although this type of fungicide has a unique mechanism of action, the pathogenic bacteria develop resistance...
