Problems solved by technology

[0005] Although fluazinam has good bactericidal activity against many plant disease pathogens, it cannot penetrate the protective layers such as cuticles and waxes on the plant surface due to its lack of systemic properties. The control effect is very unsatisfactory

Embodiment 1

[0042] Take the original drug of fluazinam containing 10.5g of active ingredients, 3.0g of sodium alkylphenol polyoxyethylene ether sulfate, 12.0g of calcium lignosulfonate, 1.5g of polyethylene glycol, 0.5g of organic silicone, and 6.0g of carboxycellulose g, 0.5g of fatty alcohol polyoxyethylene ether, 100g of diatomaceous earth, after mixing and stirring evenly, add 200g of water, wet grinding to make a suspension, and then spray, dry and sieve to obtain 10% fluridine Amine dry suspending agent. After testing, the active ingredient content is 10.2%, moisture ≤ 1.0%, pH 7.8, fineness (through 45um) ≥ 98%, suspension rate ≥ 90%, persistent foaming (1min) ≤ 10ml, wetting time ≤ 40s, Basically no dust, accelerated storage stability is qualified.

Embodiment 2

[0044] Take the original drug of fluazinam containing 31.0g of active ingredients, 4.0g of sodium methylene bis-naphthalene sulfonate, 8.0g of pull-open powder, 1.5g of polyethylene glycol, 0.5g of organic silicone, 10.0g of white carbon black, fat Alcohol polyoxyethylene ether 1.0g, diatomaceous earth make up 100g, mix and stir evenly, add water 300g, wet grinding to make suspending agent, and then spray, dry and sieve to get 30% fluazinam dry suspension agent. After testing, the active ingredient content is 30.5%, moisture ≤ 1.0%, pH 8.0, fineness (through 45um) ≥ 98%, suspension rate ≥ 90%, persistent foaming (1min) ≤ 10ml, wetting time ≤ 40s, Basically no dust, accelerated storage stability is qualified.

Embodiment 3

[0046] Take fluazinam original drug containing 31.0g active ingredient, castor oil polyoxyethylene ether 4.0g, lignosulfonate 6.0g, polyethylene glycol 1.5g, organosilicone 0.5g, white carbon black 5.0g, sulfuric acid Ammonium 18.0g, polyether modified siloxane 0.8g, kaolin to make up 100g, after mixing and stirring evenly, add 300g of water, wet grinding to make a suspension, and then spray, dry, and sieve to obtain 30% fluoride Pyridine amine dry suspension concentrate. After testing, the active ingredient content is 30.4%, moisture ≤ 1.0%, pH 7.9, fineness (through 45um) ≥ 98%, suspension rate ≥ 90%, persistent foaming (1min) ≤ 10ml, wetting time ≤ 40s, Basically no dust, accelerated storage stability is qualified.

Abstract

The invention discloses an agricultural bactericide, namely a fluazinam dry suspending agent and a preparation method thereof. The composition provided by the invention comprises fluazinam, a penetrating agent, a dispersing agent, a wetting agent, a disintegrating agent, a binder, a filler and water. The preparation method of the fluazinam dry suspending agent technically adopts multiple grindingso that the particle size of the dry suspending agent is controlled below 5 mu m and the suspensibility is more than 90%. The fluazinam dry suspending agent and the preparation method provided by theinvention have the characteristics of high drug effect, strong penetration capability and the like, can reduce the dosage, lower the using cost of farmers, reduce environmental pollution and resist rainwash, and well solves the problem that fluazinam is difficult to penetrate into the plants, thereby greatly improving the prevention and control effect on the crop diseases.

Description

(1) Technical field [0001] The invention relates to a pesticide fungicide, in particular to a fluazinam dry suspension and a preparation method thereof. (2) Background technology [0002] At present, emulsifiable concentrates, wettable powders, powders, etc. are more commonly used in the frequently used pesticide formulations, and these formulations can play a better role in specific environments and conditions. However, as humans pay more and more attention to environmental protection, higher requirements are placed on the use of pesticides, so these formulations have their corresponding limitations. [0003] For this reason, pesticide experts are constantly pursuing and exploring new pesticide formulations that are more efficient, safer, and more environmentally friendly. Among them, dry suspension concentrate (DF) is one that has been successfully developed. At present, in some western developed countries, dry suspension concentrates have been developed relatively mature...
