preparation Embodiment 1

[0039] (1) Preparation of rectification oak wood vinegar:

[0040] a. Carry out dry distillation of fresh oak wood, collect steam gas, condense and separate, and collect liquid products;

[0041] b. After precipitating the liquid product collected in step a for 48 hours, add activated carbon for adsorption for 20 hours;

[0042] c. Rotary evaporation at 39.5°C, the evaporation pressure is -0.35kPa, and the remaining volume is 30% of the original volume;

[0043] d. Use a cellulose acetate organic filter membrane with a pore size of 0.1 μm to filter the rotary evaporated liquid twice to obtain clear and transparent yellow oak wood vinegar.

[0044] (2) Preparation of benzaldehyde amino L-cysteine ​​Schiff base:

[0045] First add 5ml of distilled water to 20mmol (about 2.423g) of L-cysteine ​​and stir to make it dissolve to the greatest extent, then add 90ml of absolute ethanol and stir. Add 2.0ml benzaldehyde (density 1.044-1.047, concentration 98.5%, molecular weight 106.1...

Abstract

The invention relates to a wood-vinegar alkaline insecticide composition and a preparation method thereof. The wood-vinegar alkaline insecticide composition disclosed by the application is composed of 1000 parts by weight of mongolian oak wood-vinegar liquid, 0.08-0.12 part by weight of benzaldehyde semicarbazone L-cysteine schiff base and 0.001-0.010 part by weight of salicylic acid. The wood-vinegar alkaline insecticide composition disclosed by the invention is low in toxicity, and safe to a human body, has no pollution to environment and does not have residues in medicated object, as well as is an efficient and low-toxicity excellent insecticide.

Description

technical field [0001] The application relates to the field of pesticides, in particular to a wood vinegar base pesticide composition comprising wood vinegar and benzaldehyde amino L-cysteine ​​Schiff base and a preparation method thereof. Background technique [0002] Phenoloxidase (EC.1.14.18.1, PO for short) is a copper-containing metalloenzyme present in insects. It is a key enzyme for the synthesis of melanin in organisms and plays an important role in the growth and development of insects. key enzymes. At the same time, this enzyme is also related to the tanning effect in the process of molt of insects, and is an important enzyme that insects depend on for survival. Existing research results have shown that phenoloxidase inhibitors can be used to inhibit the activity of phenoloxidase to hinder the tanning of insects during molting, thereby achieving the insecticidal effect. At present, there is no report on the design of inhibitors against phenol oxidase for use as i...
