Embodiment 1

[0025] Example 1: 11% boscalid carvacrol water dispersible granules

[0026] Weigh 10% boscalid, 1% carvacrol, 5% calcium dodecylsulfonate (wetting agent), 4% lignosulfonate (dispersant), urea (disintegrant) 2%, polyethylene glycol (binding agent) 3%, gum arabic (stabilizer) 3%, kaolin supplemented to 100%. 11% boscalid·carvacrol water-dispersible granules are prepared by dry crushing, granulating, drying and sieving the above formula according to the proportion.

[0027] The above-mentioned 11% boscalid·carvacrol water-dispersible granule was used to prevent and control strawberry gray mold. It was diluted with water to 1000 times liquid and sprayed evenly at the early stage of the disease, and the control effect was 92.7% after 3 days of application. 20% boscalid water dispersible granules 800 times liquid and 5% carvacrol water dispersible granules 600 times liquid were used as control agents, applied in the same way, and the 3d control effects were 76.4% and 79.8% respect...

Embodiment 2

[0028] Example 2: 21% boscalid carvacrol water dispersible granules

[0029] Weigh 20% boscalid, 1.0% carvacrol, 3.5% sodium alkylbenzenesulfonate, 3% lignosulfonate, 4% sodium lauryl sulfate, 5% ammonium sulfate, starch Top up to 100%. The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 21% boscalid·carvacrol water dispersible granules.

[0030] The above-mentioned 21% boscalid·carvacrol water-dispersible granule was used to prevent and control cucumber gray mold. In the early stage of the disease, it was diluted with water to 800 times of liquid and sprayed evenly. The control effect was 89.5% after 3 days of application. Using 50% boscalid water dispersible granules 800 times liquid and 5% carvacrol water dispersible granules 300 times liquid as control agents, the same method was used to apply the drugs, and the 3d control effects were 75.2% and 76.3% respectively. The test showed that 21% boscalid·carvacrol water-dispers...

Embodiment 3

[0031] Embodiment 3: 5.5% boscalid·carvacrol suspension concentrate

[0032] Weigh 5.0% of boscalid, 0.5% of carvacrol, 4% of sodium lignosulfonate, 5% of sapindus powder, 0.1% of silicone compounds, 0.2% of xanthan gum, and 2% of ethylene glycol. %, calcium alkylbenzenesulfonate 2%, and deionized water to make up to 100%, after mixing evenly, 5.5% boscalid·carvacrol suspension was prepared by grinding and high-speed shearing.

[0033] The above-mentioned 5.5% boscalid·carvacrol suspension was used to prevent and control botrytis cinerea, diluted with water to 800 times liquid and sprayed evenly at the early stage of the disease, and the control effect was 95.3% after 3 days of application. Using 800 times solution of 20% boscalid suspension concentrate and 800 times solution of 5% carvacrol suspension concentrate as control agents, the control effects were 83.2% and 78.3% after 3 days of application by the same method. Tests have shown that 5.5% boscalid·carvacrol suspension...

Abstract

The invention relates to a bactericidal composition containing boscalid and carvacrol. The active ingredients are composed of the boscalid and carvacrol, wherein a weight ratio of the boscalid to the carvacrol is (5-20):1. The bactericidal composition disclosed by the invention is obvious in synergistic interaction, is applicable to control of gray molds of crops such as melons, vegetables, fruit trees and the like, can reduce the cost of pesticides and contributes to prolonging the life cycle of the boscalid.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to a bactericidal composition containing boscalid and carvacrol. Background technique [0002] Boscalid, English name: boscalid, is a new type of nicotinamide fungicide, mainly used for the prevention and treatment of gray mold, powdery mildew, brown rot and root rot, boscalid mainly inhibits mitochondrial succinic acid Dehydrogenase, hinders the tricarboxylic acid cycle, interferes with cell division and growth; can inhibit spore germination, mycelium growth and spore mother cell formation. As a new type of fungicide, boscalid has a good control effect on Botrytis cinerea, but the production and use costs are high, and there is a great risk of resistance when used alone for a long time [0003] Plant essential oil is a general term for a class of aromatic and volatile oily liquids extracted from plants. Plant essential oils have good antibacterial and antioxidant ac...
