Embodiment 1

[0020] Aconitine mother liquor configuration: Dissolve 10g of aconitine in 100mL of DMSO, containing 10g of bifenazin, 80g of phoxim, and 10g of aconitine mother liquor.

[0021] According to the formula requirements, using water as the medium, add active ingredients, wetting agents, dispersants, thickeners, defoamers, etc. into a sand mill for grinding, and then emulsify to obtain a suspension.

[0022] The leaves and leaf segments of the grape plants in the greenhouse were taken and placed in a multi-well plate (24-well plate) cultured with water agar, and the leaves or leaf segments were pre-sprayed with test solutions of different concentrations. After spraying, the pathogen downy mildew was inoculated, and after cultivating for 9 days, the inhibition rate was calculated according to the area of ​​the leaves not infected with the pathogen. The inhibition rate of the multipurpose pesticide composition with a concentration of 200PPM is 80%.

Embodiment 2

[0024] Aconitine mother liquor configuration: 10 g of aconitine is dissolved in 100 mL of DMSO, and the pesticide composition of the present invention contains 9 g of bifenazate, 80 g of phoxim, and 11 g of aconitine mother liquor.

[0025] According to the formula requirements, using water as the medium, add active ingredients, wetting agents, dispersants, thickeners, defoamers, etc. into a sand mill for grinding, and then emulsify to obtain a suspension.

[0026] Get the leaves and leaf segments of barley in the greenhouse, place them in a multi-well plate (24-well plate) with water agar culture, and spray the test solution with a concentration of 200PPM on the leaves or leaf segments in advance. After spraying, inoculate the pathogenic bacterium net spot bacterium, and after culturing for 9 days, calculate the inhibition rate according to the area of ​​the leaves not infected with pathogenic bacteria. The composition with a concentration of 20PPM has an inhibitory rate of 5...

Embodiment 3

[0028] Take 10g of aconitine and dissolve it in 100mL of DMSO. The pesticide composition of the present invention contains 8g of bifenazate, 70g of phoxim, and 22g of aconitine mother liquor.

[0029] According to the formula requirements, using water as the medium, add active ingredients, wetting agents, dispersants, thickeners, defoamers, etc. into a sand mill for grinding, and then emulsify to obtain a suspension.

[0030] Take the mycelium or spore suspension of the pathogenic bacteria of wheat leaf spot (made by directly mixing fresh liquid culture medium or preserved frozen solution into nutrient broth), take 20 μL of the test solution with a concentration of 20PPM into a 96-well plate, and then Add the suspension with pathogenic bacteria, and carry out dark culture at 24°C and 96% humidity. After 7 days, calculate the fungal inhibition rate by measuring the optical density. The composition with a concentration of 20PPM has an inhibitory rate of 100% on wheat leaf spot. ...

Abstract

The invention relates to a multi-purpose pesticide composition, the active ingredients are bifenazate, phoxim and aconitine mother liquor, containing 1-10% of bifenazate, 1-80% of phoxim, and aconitine mother liquor 1 to 30%. The combination of the three in the present invention has obvious synergistic effect of sterilizing and killing mites, and improves the control effect on harmful mites compared with a single agent used alone. And aconitine, as a bactericidal and antibacterial agent, can effectively inhibit a variety of plant pathogenic bacteria. The aconitine of the invention has a wide range of sources, is natural and does not need to be synthesized, can effectively expand the scope of antibacterial agents, and realize resource diversification.

Description

technical field [0001] The invention relates to a multipurpose pesticide composition, which belongs to the field of pesticides. Background technique [0002] A variety of pests on vegetables and fruit trees. As the main means of chemical control of farmland pests, pesticides are currently widely used. However, long-term use of a single type of pesticide will lead to resistance of pests. Due to the mixed occurrence of multiple pests on the same crop, repeated application will increase labor costs. Field experiments have shown that mixing pesticides with different mechanisms of action can not only delay the emergence of drug resistance, but also expand the insecticidal spectrum, effectively control a variety of pests, reduce environmental pollution, and reduce labor costs, which has good economic benefits. [0003] Phoxim, also known as phosphoxime and cyanoxime, is a highly efficient, low-toxic, broad-spectrum organophosphorus insecticide An agent whose mechanism of actio...
