Embodiment 1

[0035] Example 1 30% Benzostrobin Dimethomorph Suspension Concentrate

[0036] The raw material formula is as follows (mass percentage): 15% of dimethomorph, 15% of benzstrobin, 1% of castor oil ethylene oxide adduct, 1% of ethylene oxide-propylene oxide block copolymer , Alkylnaphthalene Formaldehyde Condensate 2%, Glycerin 5%, Magnesium Aluminum Silicate 0.5%, Xanthan Gum 0.2%, Organic Silicone 0.4%, Benzoic Acid 0.4%, Isothiazolinones 0.2%, Water Make Up to 100%

[0037] The preparation method is as follows: weigh each material according to the above ratio and mix them into a mixture. After preliminary shearing and mixing by a shearing machine, add it to a sand mill and grind it at a speed of 2000r / min for about 3 hours, and stop grinding when the particle size is 98%<3 μm. The suspending agent was prepared by vacuum defoaming.

[0038] Suspending agent refers to the technical indicators as follows: the appearance is a flowable viscous uniform suspension, the average part...

Abstract

The invention relates to a benzothiostrobin-containing and dimethomorph-containing bactericidal composition and an application of bactericidal composition. The composition is composed of active ingredients and pesticide preparation auxiliary ingredients, wherein the active ingredients are composed of dimethomorph and benzothiostrobin in a weight ratio of (0.1 to 10):1. According to the composition disclosed by the invention, benzothiostrobin and dimethomorph are compounded in a certain ratio range, so that firstly, a remarkable synergistic effect is obtained, and the medication times are reduced, so that the cost is saved; secondly, the two active ingredients in the bactericidal composition are two types of bactericidal agents with different action mechanisms, thus expanding a prevention and treatment spectrum, slowing down the generation of medicine resistance, and prolonging the service life of the medicament; thirdly, the active ingredients of the composition are both high-efficiency, low-toxicity and environment-friendly pesticides, and slightly influence the ecological environment.

Description

technical field [0001] The invention relates to a bactericidal composition containing fenthiastrobin. Background technique [0002] Benthiastrobin is a new type of methoxyacrylate fungicide, which can effectively inhibit the mitochondrial respiration of plant pathogens, thereby playing a bactericidal role of protection, treatment and eradication. It is a high-efficiency, broad-spectrum, low-toxicity environmentally friendly fungicides. In addition, benzothiastrobin can also directly kill pathogenic bacteria that have invaded plants. For almost all fungal diseases (Ascomycotina, Basidiomycotina, Flagellate and Deuteromycotina) diseases such as powdery mildew, rust, glume blight, net spot, downy mildew, rice blast, etc. All have good activity. Benthiostrobin can be used for stem and leaf spray, seed treatment, and soil treatment, mainly for grain, rice, peanut, grape, potato, fruit tree, vegetable, coffee, lawn, etc. [0003] Dimethomorph is a fungicide specific for oomyce...
