Embodiment 146

[0033] Example 146% Benzostrobin Cymoxanil Suspension Concentrate

[0034] The raw material formula is as follows (mass percentage): 44% cymoxanil, 2% benzathystrobin, 2% polycarboxylate, 2% EO-PO block copolymer, castor oil ethylene oxide adduct 2% %, ethylene glycol 5%, xanthan gum 0.1%, magnesium aluminum silicate 1%, benzoic acid 0.5%, defoaming silicone oil 0.4%, water to make up to 100%.

[0035] 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 90%<3 μm. The sanding medium was removed by filtration to prepare a suspension.

[0036] The technical indicators of the suspending agent are as follows: the appearance is a flowable viscous uniform suspension, the average particle size is 98%<3μm, the suspension rate is 95%, and it i...

Abstract

The invention relates to a benzothiostrobin-containing and cymoxanil-containing bactericidal composition and application of bactericidal composition. The bactericidal composition is composed of active ingredients and pesticide preparation auxiliary ingredients, in particular, the active ingredients are composed of cymoxanil and benzothiostrobin in a weight ratio of (0.05 to 20):1. According to the composition disclosed by the invention, benzothiostrobin and cymoxanil are compounded in a certain ratio range, thus obtaining a remarkable synergistic effect, expanding a bactericidal spectrum, slowing down the generation of medicine resistance, and prolonging the service life of the medicament; moreover, due to the compounding, the efficacy is remarkably enhanced, the use dosage is reduced, and the prevention and treatment cost is effectively reduced. The composition disclosed by the invention has an extremely good prevention and treatment effect on cucumber downy mildew.

Description

technical field [0001] The invention relates to a bactericidal composition containing fenthiastrobin. Background technique [0002] Penthiastrobin is a methoxyacrylate fungicide, and its mechanism of action is to inhibit mitochondrial respiration. It is an environmentally friendly fungicide with high efficiency, broad spectrum and low toxicity. Penthiostrobin is a therapeutic fungicide, which is mainly applied after the plant is infected. It can quickly penetrate and systemically absorb into the plant, and directly kill the pathogenic bacteria that have invaded the plant. Due to its good protection, treatment, and eradication bactericidal effects, benzothiastrobin has good effects on powdery mildew, stripe rust, downy mildew, leaf spot, rice blast, and sheath blight on fruit trees, vegetables, and cereal crops. prevention effect. [0003] Cymoxanil is a high-efficiency, low-toxicity fungicide, which is effective against peronospora fungi such as Phytophthora, Peronospora, ...
