Embodiment 1

[0028] Boscalid 2g, metconazole 6g, chlorothalonil 10g, sodium dodecylbenzene sulfonate 2g, NNO-1 2g, pull open powder 2.5g, attapulgite 20g, and diatomaceous earth to supplement the rest to 100g . The above components are fully mixed, pulverized by a sand mill and passed through a 300-mesh sieve to obtain a wettable powder with an active ingredient content of 18% boscalid·metconazole·chlorothalonil.

Embodiment 2

[0030] Boscalid 12g, metconazole 36g, chlorothalonil 12g, glycerin 4g, propylene glycol 4g, NNO-1 1g, NNO-7 1g, xanthan gum 0.5g, polyethylene glycol 1g, the rest is supplemented with water to 100g , fully mix the above components, and pulverize them with a sand mill until the diameter of 90% of the medicament particles is less than or equal to 5 μm, to obtain a suspension concentrate with an active ingredient content of 60% boscalid, metconazole, and chlorothalonil.

Embodiment 3

[0032] Boscalid 8g, metconazole 8g, chlorothalonil 8g, N-methylpyrrolidone 1g, calcium alkylbenzenesulfonate 2g, phenethylphenol formaldehyde resin polyoxyethyl ether 2g, ethylene glycol 1.5g , 0.8g of silicone compounds, 1g of xanthan gum, 1g of magnesium aluminum silicate, and the rest is supplemented with water to 100g.

[0033] Add boscalid, metconazole, chlorothalonil, solvent N-methylpyrrolidone, emulsifier calcium alkylbenzenesulfonate and phenethylphenol formaldehyde resin polyoxyethyl ether in the above ratio, dissolve Form a uniform oil phase; mix water, antifreeze ethylene glycol, thickener xanthan gum, and defoamer silicone compounds to form a uniform water phase. Under high-speed stirring, the water phase is added to the oil phase to prepare the microemulsion of boscalid, metconazole, and chlorothalonil with an active ingredient content of 24%.

Abstract

The invention belongs to the technical field of pesticide and discloses a bactericidal composition and application thereof. The bactericidal composition comprises active components of boscalid, metconazole and chlorothalonil in the weight ratio of 1-20: 1-20: 1-40. The bactericidal composition has obvious synergistic effect on the prevention and control of soybean rust, bean rust, pear rust, wheat gibberellic disease, wheat powdery mildew, wheat rust, wheat banded sclerotial blight, wheat leaf blight, rice blast, rice false smut and rice sheath blight of rice, especially more obvious synergistic effect on the prevention and control of soybean rust, kidney bean rust and pear rust. The composition can greatly reduce the dosage and the frequency of application, reduce the production cost, reduce the environmental pollution and pesticide residue in agricultural production, and has important practical significance to increase the social, economic and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a ternary fungicide composition containing boscalid, metconazole and chlorothalonil with synergistic and weight-reducing effects and an application thereof. Background technique [0002] Boscalid, English common name: Boscalid, chemical name: 2-chloro-N-(4’-chlorodiphenyl-2-yl) nicotinamide, molecular formula: C 18 h 12 Cl 2 N 2 O, its chemical structure is as follows: [0003] [0004] Boscalid is a new type of nicotinamide fungicide, which acts on succinate coenzyme Q reductase in the mitochondrial respiratory chain, hinders the tricarboxylic acid cycle, causes amino acid and sugar deficiency, energy reduction, and interferes with cell division and growth. The disease has nerve activity and has protective and therapeutic effects. Inhibit the main stages of fungal growth and reproduction such as spore germination, germ tube extension, mycelial growth and s...
