Embodiment 1

[0010] Accurately weigh and analyze the pyrethrin content in the refined natural pyrethrin original drug, add 0.2% of the pyrethrin content in the original drug stabilizer BHT (p-cresol), and then add 50% of the pyrethrin content in the original drug The synergist tangerine oil is stirred and dissolved, and the emulsifier (5201) is diluted with an appropriate amount of acetone solution, and then 10% of the emulsifier of the pyrethrin content in the original drug is added, and after stirring evenly, turpentine is added until the pyrethrin content is 1%, to obtain 1% natural pyrethrin emulsifiable concentrate preparation.

Embodiment 2

[0012] Accurately weigh and analyze the pyrethrin content in the refined natural pyrethrin original drug, add 0.3% of the pyrethrin content in the original drug stabilizer BHT (p-cresol), and then add 100% of the pyrethrin content in the original drug Stir the synergist capillary, dilute the emulsifier (5201) with an appropriate amount of acetone solution, add 15% emulsifier of the pyrethrin content in the original drug, and then add turpentine until the pyrethrin content is 2%, to obtain 2% natural pyrethrin emulsifiable concentrate preparation.

Embodiment 3

[0014] Accurately weigh and analyze the pyrethrin content in the refined natural pyrethrin original drug, add 0.4% of the pyrethrin content in the original drug stabilizer BHT (p-cresol), and then add 200% of the pyrethrin content in the original drug Stir the synergist lemon oil to dissolve, dilute the emulsifier (2201) with an appropriate amount of acetone solution, then add 20% of the emulsifier with the content of pyrethrins in the original drug, stir evenly, then add turpentine until the content of pyrethrins is 3%, to obtain 3% Natural pyrethrin emulsifiable concentrate preparation.

Abstract

The present invention relates to a kind of natural pyrethrin cream preparation. The natural pyrethrin cream preparation consists of natural pyrethrin, stabilizer BHT or tannic acid 0.2-0.7 (wt% of pyrethrin, the same below), matter containing limolene component as synergist 50-300, emulsifier 10-30 and proper amount of pinene component. The natural pyrethrin cream preparation has all its solvent, synergist and stabilizer being plant extract and has high efficiency, low toxicity, no residue and no harm to plant, so that it may be used to replace available high toxicity pesticide in producing green food and organic food material.

Description

technical field [0001] The invention relates to an insecticide, in particular to a natural pyrethrin emulsifiable concentrate preparation. Background technique [0002] Most of the existing pesticide technical materials and pesticide preparations are organochlorines, organophosphorus, carbamates or pyrethroids. These pesticides have pesticide residues after use, causing many harms to humans, seriously polluting the environment, and causing pests The resistance to insecticides is getting stronger and stronger, and only by gradually increasing the dosage of insecticides can the pests be overcome. [0003] Natural pyrethrins have many advantages such as slight toxicity to warm-blooded animals, fast knockdown of pests, high mortality, easy degradation, no pollution to agricultural products and the environment, and no resistance to pesticides in pests after long-term use. But the solvent that is routinely used for pyrethrum is kerosene or sherwood oil, and the synergist is PBO (...
