Embodiment 3

[0015] Preparation Example 3: 60% carvacrol · fluazinam water dispersible granules.

[0016] Carvacrol 3%, Fluazinam 57%, Sodium Lauryl Sulfate 6%, Dispersant Lignosulfonate 4%, Disintegrant Sodium Chloride 2%, Binder Polyethylene Glycol 3%, Stabilized soluble starch 3%, kaolin supplemented to 100%. The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 60% carvacrol·fluazinam water dispersible granules.

Embodiment 4

[0017] Formulation Example 4: 50% carvacrol · fluazinam water dispersible granules.

[0018] Carvacrol 1.5%, Fluazinam 48.5%, Sodium Lauryl Sulfate 6%, Dispersant Lignosulfonate 4%, Disintegrant Sodium Chloride 2%, Binder Polyethylene Glycol 3%, Stabilized soluble starch 3%, kaolin supplemented to 100%. The above formula is dry pulverized in proportion, granulated, dried and sieved to prepare 50% carvacrol·fluazinam water dispersible granules.

[0019] Formulation Example 5: 50% carvacrol fluazinam wettable powder.

[0020] Carvacrol 1%, fluazinam 49%, pull open powder 3%, lignosulfonate 6%, talcum powder 15%, kaolin supplemented to 100%. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 50% carvacrol·fluazinam wettable powder.

[0021] Formulation Example 6: 60% carvacrol · fluazinam wettable powder.

Embodiment 1

[0023] Bioassay Example 1: Indoor Toxicity Test of Carvacrol and Fluazinam to Botrytis cinerea

[0024] Test method: refer to NY / T 1156.6-2006. That is, first weigh a certain mass of 95% carvacrol and 95% fluazinam original drug, add acetone to fully dissolve, dilute with 0.1% Tween 80 aqueous solution, and prepare single-dose mother solutions respectively, and set the following series according to the purpose of mixing Proportion (6:1 / 3:1 / 1:1 / 1:3 / 1:9 / 1:30 / 1:50).

[0025] Taking the logarithm value of the drug concentration (μg / ml) as the independent variable x, and taking the probability of inhibition rate as the dependent variable y, the toxicity regression equations were respectively established, and the EC50 (95 % confidence limit) and the co-toxicity coefficient (CTC) of the mixture was calculated by Sun Yunpei's method.

[0026] According to the classification standard of NY / T 1156.6-2006 fungicide joint action: co-toxicity coefficient (CTC) ≥ 120 means synergistic e...

Abstract

The invention discloses a carvacrol-fluazinam pesticide composition. The carvacrol-fluazinam pesticide composition comprises common assistants, carvacrol and fluazinam, wherein a mass part ratio of carvacrol to fluazinam in the carvacrol-fluazinam pesticide composition is in a range of (6: 1) to (1: 50) and preferably, the mass part ratio is in a range of (3: 1) to (1: 30). Through combination of carvacrol and fluazinam, the obvious synergistic effect is obtained. A use amount of active ingredients of the carvacrol-fluazinam pesticide composition is less than a use amount of carvacrol or fluazinam used individually. The carvacrol-fluazinam pesticide composition is suitable for crop botrytis caused by Botrytis pathogens.

Description

technical field [0001] The pesticide composition involved in the invention uses carvacrol and fluazinam as active components and is suitable for preventing and treating botrytis cinerea caused by botrytis pathogens. Background technique [0002] Carvacrol, English common name carvacrol, chemical name: 2-methyl-5-isopropylphenol. Carvacrol is a plant extract, which has a good control effect on botrytis cinerea caused by botrytis pathogens and is environmentally friendly. [0003] Fluazinam, English common name fluazinam, chemical name: 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-di Nitro-p-toluidine. Fluazinam is a protective fungicide. The current commercial dosage form is suspension concentrate, and the main method of use is to spray stems, leaves and soil. [0004] Botrytis cinerea is the main cause of botrytis cinerea in various crops. [0005] At present, there is no report on the compounding of carvacrol and fluazinam to control botrytis ci...
