Effect test

Embodiment 1

[0020] Tea Saponin 40%

[0021] Abamectin 0.5%

[0022] Dimethylformamide 5%

[0023] Butanol 5%

[0024] QK-1 Emulsifier 10%

[0025] OP-9 2%

[0026] water balance

[0027] After the abamectin is dissolved in dimethylformamide, other components are added according to the formula to obtain a 40.5% saponin avemectin water-soluble concentrate. The preparation diluted 3000 times has a control effect on apple spider mites of 96% on the third day, and the control effect of the contrast drug 1.8% abamectin EC 3000 times on the third day is 87.7%.

Embodiment 2

[0029] Tea Saponin 14.5%

[0030] Abamectin 0.5%

[0031] Cyclohexanone 3%

[0032] QK-2 Emulsifier 15%

[0033] JFC 2%

[0034] Butanol 5%

[0035] water balance

[0036] After dissolving the avermectin with cyclohexanone, other components are added, and finally water is added under stirring to obtain 15% tea saponin avi microemulsion. The insecticidal rate of 1500 times of liquid of this preparation against resistant Plutella xylostella after 24h is 86%, the insecticidal rate of 1.8% avermectin emulsifiable concentrate of contrast agent 1500 times of liquid is 73.8%, and the insecticidal rate of 1500 times of liquid of 50% tea saponin water agent is 86%. The insecticidal rate is 14%.

Embodiment 3

[0038] Tea Saponin 30%

[0039] Emamectin Benzoate 0.5%

[0040] Dimethylformamide 5%

[0041] Butanol 5%

[0042] QK-1 10%

[0043] Azone 1%

[0044] water balance

[0045] Processed into 30.5% saponin avi saline soluble concentrate by the method of embodiment 1. The control effects of 1000 times liquid of this preparation and 1000 times liquid of 1% emamectin emamectin emulsifiable oil against resistant beet armyworm were 94.2% and 93.7% respectively after 3 days of application.

Abstract

The invention relates to a composition of tea saponin and abamectin for killing pests and mite, which is characterized in that the weight percentage of tea saponin is 2-40% and abamectin is 0.2-5%, meanwhile residue are additive, solvent and water. The agent may be water-soluble additive and microemulsion. The composition can effectively prevent the agriculture pest and mite and reduces the effective dosage of the abamectin and delays the generation of the drug resistance.

Description

Technical field: [0001] The invention relates to an agricultural insecticide and acaricide, in particular to an insecticide and acaricide containing tea saponin and abamectin. Background technique: [0002] Abamectin is a macrolide biological insecticide and acaricide produced through the metabolism of biological fermentation bacteria. The pure product is white crystal with molecular formula C 48 h 72 o 14 , the molecular weight is 873.11, and the melting point is 157-162°C. Soluble in polar organic solvents such as methanol, ethanol, acetone, insoluble in non-polar solvents such as aliphatic hydrocarbons, insoluble in water. Abamectin has an ideal killing effect on common agricultural pests and mites such as spider mite, white spider, diamondback moth, leafminer, pear psyllid, whitefly, etc., and has no interactive resistance with other insecticides and acaricides It is an important ultra-high-efficiency biological insecticide and acaricide species at present. Emamect...
