Problems solved by technology

[0004] Due to the long-term use of the above two agents alone, it is easy to lead to the emergence of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a significant increase in dosage, shortened spraying cycles, and poor use effects, which increases costs. The use of a large number of pesticides makes the bacteria The resistance is more serious, and it also has a certain impact on the environment. The drug residues in agricultural products have also increased, which affects the health and normal survival of humans and animals. The compound use of eclopyrazole and fluazinam to prevent and control crop diseases, the domestic Not yet reported

Embodiment 1

[0023] Step 1: Weigh the following components in weight percentage respectively: 10% of eucumazole, 20% of fluazinam, 6% of lignosulfonate, 10% of pulling powder, 12% of magnesium aluminum silicate, 3% of xanthan gum %, and the balance makes up 100% with bentonite.

[0024] Step 2: Mix the components weighed in Step 1 together, stir evenly, and prepare a slurry with a solid content of 65% with water, put the slurry into a sand mill, and grind it into a suspension. Then spray drying and granulation;

[0025] Step 3: Spray granulation with a pressure spray dryer, and sieve after drying to obtain a 100-mesh dry suspension, grind the suspension with a sand mill to have a particle size of 5 mm, and a suspension rate of 95%.

[0026] Step 4: Pack the medicine prepared in Step 3 and store it in the warehouse.

Embodiment 2

[0028] Step 1: Weigh the components in the following weight percentages respectively: 30% of ebuazole, 10% of fluazinam, 20% of sodium alkylnaphthalene sulfonate, 1% of saponin, 6% of urea, 2% of sodium alginate, and The amount is made up to 100% with attapulgite.

[0029] Step 2: Mix the components weighed in step 1 together, stir evenly, and prepare a slurry with a solid content of 30% with water, put the slurry into a sand mill, and grind it into a suspension. Then spray drying and granulation;

[0030] Step 3: Spray granulation with a pressure spray dryer, and sieve after drying to obtain a 30-mesh dry suspension, grind the suspension with a sand mill to have a particle size of 1 mm, and a suspension rate of 92%.

[0031] Step 4: Pack the medicine prepared in Step 3 and put it into the warehouse.

Embodiment 3

[0033] Step 1: Weigh the following components in weight percentage respectively: 18% of eubazole, 15% of fluazinam, 10% of sodium alkylnaphthalene sulfonate, 5% of polyvinyl chloride, 6% of sodium sulfate, 1% of gum arabic, The balance is made up to 100% with diatomaceous earth.

[0034] Step 2: Mix the medicines weighed in step 1 together, stir evenly, and prepare a slurry with a solid content of 50% with water, put the slurry into a sand mill, and grind it into a suspension liquid, and then spray-dried and granulated;

[0035] Step 3: Spray granulation with a pressure spray dryer, after drying, sieve to obtain 80-mesh dry suspension, grind the suspension with a sand mill, the particle size is 4mm, and the suspension rate is 96%.

[0036] Step 4: Pack the medicine prepared in Step 3 and put it into the warehouse.

Abstract

The invention relates to a dry suspending agent containing bismerthiazol and fluazinam. The dry suspending agent is prepared from the following components in percentage by weight: 10%-30% of bismerthiazol, 10%-20% of fluazinam, 6%-20% of a dispersant, 1%-10% of a wetting agent, 1%-12% of a disintegrating agent, 0.3%-3% of a suspending aid and the balance of a carrier. The invention further relates to a preparation method of the dry suspending agent containing bismerthiazol and fluazinam. The dry suspending agent containing bismerthiazol and fluazinam has the beneficial effects that the composition has a synergistic effect after being compounded and a prevention and treatment range is enlarged; the prevention and treatment on bacterial diseases is increased; the dry suspending agent has a better effect in fungal diseases of fruit trees or grain crops, and particularly has a remarkable effect on citrus scab, citrus canker, apple scab, rice bacterial leaf blight, rice blast and the like; and the drug resistance is not easy to generate and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a dry suspension containing euconazole and fluazinam and a preparation method thereof. Background technique [0002] Yebazole, also known as Yeqingshuang, is a long white columnar crystal or light yellow loose fine powder, which is a low-toxicity fungicide. Non-carcinogenic, teratogenic, mutagenic, efficient and safe systemic fungicide, with good preventive and therapeutic effects. It is mainly used to prevent and control plant bacterial diseases. It has a long-lasting effect and stable drug effect. It has good control effects on rice bacterial blight, bacterial streak disease and citrus canker. [0003] Fluazinam (Fluazinam) is a 2,6-dinitroaniline compound, which is a broad-spectrum protective fungicide against Alternaria, Botrytis, Phytophthora, Unipota, Sclerotinia and Scab bacteria are very effective. The specific diseases that fluazinam can control include cucumber pepper bli...
