Embodiment Construction

[0013] specific implementation plan

[0014] In the generator, add the following products in the following order: water 24 kg, solid potassium hydroxide 8.5 kg, isopropanol 29 kg, oleic acid 38.5 kg. Stir evenly to get the product of the present invention of 100kg. The pH value of the biopesticide is 8 to 11.

[0015] Or in the generator, add the following products in the following order, by weight percentage: water 26.5kg, potassium hydroxide 7.5kg, isopropanol 28kg, oleic acid 38kg. Stir evenly to get the product of the present invention of 100kg. The pH value of the biopesticide is 9-10.

[0016] The present invention utilizes tea tree as a source of fatty acids. Extracts of Chinese camellia oil have been found to be very high in oleic acid. Tea oil contains 80% oleic acid, 8% linoleic acid, 9% palmitic acid and 1% stearic acid. Among them, monounsaturated fatty acids accounted for 83%. Specification C18:1, higher than 75%, is a product produced by Sifang Chemical Pl...

Abstract

The present invention discloses a kind of biological pesticide extracted from tea oil. The biological pesticide consists of water 22-27 wt%, solid potassium hydroxide 6-11 wt%, isopropanol 27-32 wt% and oleic acid 36-41 wt%. The biological pesticide is environment friendly, and has high pesticidal efficiency, long acting and simple preparation process and application process and use safety.

Description

technical field [0001] The present invention relates to a liquid insecticide. To be precise, it is mainly extracted from tea tree, an environmentally friendly insecticide based on soap properties. Background technique [0002] As we all know, there are many kinds of pesticides. One of the problems with chemical pesticides is that the offspring of the insects develop immunity, and the drug remains in food and water, where it can be toxic to people and plants. [0003] The use of fatty acid salts in pesticides is a known fact (see US-A-4,904,645 and US-A-5.030,658). Fatty acid salts are natural substances and are not harmful to the environment. [0004] Although the mechanism of action of fatty acid salts is not fully understood, it is a known fact that water-soluble fatty acid salts are lethal to mollusk, insect larvae, especially at high concentrations. Adults are less sensitive and can survive for a longer period of time. However, high concentrations of fatty acid salt...
