Embodiment 1

[0033] Example 1: 30% platycodon polysaccharide pyraclostrobin water dispersible granule (1:5)

[0034] Platycodon polysaccharide (active ingredient) 5%, pyraclostrobin (active ingredient) 25%, polycarboxylate (dispersant) 6.5%, calcium dodecylbenzenesulfonate (wetting agent) 5.5%, starch (viscosity) binder) 3%, sodium carbonate (disintegrant) 2.5%, kaolin (filler) to make up to 100%; mix each component evenly, after being pulverized by a jet mill, stir for 30min, knead, and then add to the fluidized bed Perform granulation, dry and sieve after granulation to obtain 30% platycodon polysaccharide pyraclostrobin water-dispersible granules.

Embodiment 2

[0035] Example 2: 33% platycodon polysaccharide pyraclostrobin water dispersible granule (10:1)

[0036] Platycodon polysaccharide (active ingredient) 30%, pyraclostrobin (active ingredient) 3%, fatty alcohol polyoxyethylene ether phosphate (dispersant) 6%, sodium lauryl sulfate (wetting agent) 5.5%, poly Vinyl alcohol (binder) 3%, sodium carbonate (disintegrant) 2.5%, diatomaceous earth (filler) 9%, kaolin (filler) to make up to 100%; mix all components evenly, and pulverize by jet mill Finally, stirring for 30 minutes, kneading, and then adding to a fluidized bed for granulation, drying and sieving after granulation to obtain 33% platycodon polysaccharide pyraclostrobin water-dispersible granules.

Embodiment 3

[0037] Example 3: 22% platycodon polysaccharide pyraclostrobin suspension concentrate (1:10)

[0038] Platycodon polysaccharide (active ingredient) 2%, pyraclostrobin (active ingredient) 20%, pull open powder (wetting agent) 3%, fatty alcohol polyoxyethylene ether phosphate (dispersant) 5%, xanthan gum ( Thickener) 2.5%, ethylene glycol (antifreeze) 3%, silicone oil (defoamer) 0.5%, deionized water (solvent) to make up to 100%; first mix other additives, in the shearing machine After shearing and mixing evenly, adding platycodon polysaccharide and pyraclostrobin, and grinding in a ball mill for 2 hours, a 22% platycodon polysaccharide pyraclostrobin suspension can be prepared.

Abstract

The invention relates to a sterilization composition. Effective ingredients consist of radix platycodonis and pyraclostrobin according to the weight ratio of (15 to 1):(1 to 20). The sterilization composition obtained by mixing the radix platycodonis and the pyraclostrobin is used for preventing and treating powdery mildew of cucumber and potato late blight; the synergistic interaction effect is obvious; the radix platycodonis is the synergist of the pyraclostrobin; the inhibition activity on the pyraclostrobin can be obviously improved. Through the mixing of the radix platycodonis and the pyraclostrobin, the use of chemicals of pyraclostrobin can also be reduced; the residue of the chemicals is reduced. Meanwhile, through the mixing of the radix platycodonis and the pyraclostrobin, the generation of the germ drug resistance can also be delayed; the prevention and treatment effects are improved.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to a bactericidal composition, in particular to a bactericidal composition for preventing and controlling cucumber powdery mildew and potato late blight in agriculture. Background technique [0002] Platycodon grandiflorus polysaccharide is one of the main active ingredients of Platycodon grandiflorus. Modern pharmacological studies have found that Platycodon grandiflorum polysaccharides have many biological activities, such as immune regulation, anti-tumor, anti-oxidation, anti-phlegm, anti-inflammatory, liver protection, anti-aging, enhancing immune function and improving insulin, etc. Research, will have high medicinal value. Chinese patent 201410628520.7 discloses a method for extracting bellflower polysaccharides, including the steps of: selecting dried bellflower, crushing it and passing it through a 40-80 mesh sieve to obtain bellflower powder, adding water to ...
