Embodiment 1

[0019] Tea Saponin 25%

[0020] Acetamiprid 3%

[0021] Dimethylformamide 12%

[0022] Methanol 15%

[0023] OK-1 Emulsifier 13%

[0024] Azone 1%

[0025] water balance

[0026] Dissolve acetamiprid in dimethylformamide according to the ratio and add other ingredients to prepare 28% tea saponin and acetamiprid microemulsion. Dilute the preparation 3000 times to control resistant apple yellow aphid. The effect reached 97.0%, the control effect of 5% acetamiprid EC 3000 times solution was 92.0%, and the control effect of 50% tea saponin aqueous solution 3000 times solution was only 26.5%.

Embodiment 2

[0028] Tea Saponin: 5%

[0029] Acetamiprid 10%

[0030] Dimethylformamide 25%

[0031] Methanol 25%

[0032] OK-2 Emulsifier 15%

[0033] water balance

[0034] The acetamiprid is dissolved in dimethylformamide, and other ingredients are added according to the proportion to prepare 15% tea saponin and acetamiprid microemulsion. The insecticidal effect of the preparation diluted 6000 times against the resistant peach aphid is similar to that of 5% acetamiprid EC 2000 times.

Embodiment 3

[0036] Tea Saponin 15%

[0037] Acetamiprid 5%

[0038] White carbon black 15%

[0039] NNO 3%

[0040] Sodium Lauryl Sulfate 1%

[0041] Clay margin

[0042] The tea saponin and other materials are mixed according to the proportion and pulverized into 320 meshes to obtain 20% tea saponin and acetamiprid wettable powder.

Abstract

The invention relates to a pesticidal composition containing tea saponin and acetamide, which is characterized in that the weight percentage of two effective components in the composition is that: 1-40% of tea saponin; 0.5-20% of acetamide. The pesticidal composition is produced into soluble thick agent, microemulsion, suspending agent and wettable powder. The pesticidal composition can effectively prevent plural pests such as aphid, hopper, scale insect, plant louse and cotton gadfly bug. The invention has a good preventing effect, conquers and delays the generation of the acetamide medicine resistance and reduces the costs of production and prevention.

Description

Technical field: [0001] The invention belongs to agricultural insecticides, in particular to an agricultural insecticide preparation containing tea saponin and acetamiprid. Background technique: [0002] Acetamiprid (acetamiprid) is a neonicotinoid ultra-efficient insecticide widely used in my country in recent years. Its molecule contains chloropyridyl and cyano groups, and its molecular formula is: C 10 h 11 ClN 4 ; Molecular weight: 222.7; Melting point: 98.9°C; Pure product is white crystal. Soluble in polar organic solvents such as methanol, ethanol, chloroform, dimethylformamide, etc., insoluble in aliphatic hydrocarbons, benzene and other solvents. Acetamiprid has the same insecticidal mechanism as the widely used imidacloprid. It is a new green and efficient insecticide after imidacloprid. It is characterized by faster insecticidal speed and better solubility in solvents (especially lower fatty alcohols) than imidacloprid. Da et al. is an ultra-efficient insectic...
