Problems solved by technology

[0006] Since January 1, 2007, my country has completely banned methamidophos and other five highly toxic pesticides. Thiazophos should be one of the important alternatives, but currently the dosage form of thiazophos is only granules (10% thiazophos GR, China People's Republic of Pesticide Registration Certificate No.: LS20020026), far from meeting the needs of the market
[0007] Thiazophos granules are unstable and easy to decompose. Thiazophos has an unpleasant smell, and the smell is long-lasting and difficult to eliminate, thus affecting the use of thiazophos to a certain extent.
[0008] A large amount of toluene, xylene and other solvents are added to traditional emulsifiable concentrates, which on the one hand increases the risk of inflammability and explosion in the production, storage and transportation of pesticides; on the other hand increases the pollution to the environment and seriously affects the survival of human beings. surroundings

Embodiment 1

[0025] Add 680L of methylated rapeseed oil and 120L of thiazole phosphorous crude oil into a mixing tank with a high-speed stirring device, start stirring to mix evenly, then add lauryl alcohol polyoxyethylene ether phosphate in batches while stirring and heating up 225kg and 900g of defoamer organic silicone; after mixing evenly, add 15kg of hydroxyethyl methylcellulose and 45kg of co-solvent ethylene glycol, stir vigorously and keep warm at 50°C for 2h; after lowering the temperature to room temperature, stir while Add 100g of 1.4-butanediamine and 450g of lemon essence, mix well, and it will become a transparent oily liquid, which is the finished product.

[0026] The cold storage stability was stored at 0°C for 7 days, the thermal stability was stored at 54±2°C for 14 days, and the emulsion stability was measured by diluting 200 times with standard hard water. The results are shown in Table 2.

Abstract

The invention discloses an environment-friendly lythidathion emulsion and a preparation method thereof. The emulsion is prepared from (wt%) lythidathion 10-80, oil 8-63, surfactant 5-25, assistants 0.5-5, cosolvent 0-5, antifoaming agent 0.05-0.5, stabilizer 0.01-1, and essence 0.01-0.5. The emulsion has the advantages of good stability, lasting drug action, low environmental pollution, simple and reasonable preparation method, and low production cost.

Description

technical field [0001] The invention relates to a formula and a preparation method of an environment-friendly thiazole phosphorus emulsion, belonging to the field of agricultural chemicals. It belongs to the field of pesticide formulation processing. Background technique [0002] Thiazophos is a novel, efficient, broad-spectrum, and safe nematocide and a pesticide for killing underground pests that was registered as a patent (60-104096) by Ishihara Corporation of Japan in June 1985 and put on the market in 1992. It is effective on tobacco, peanuts, It has a very good control effect on nematodes and underground pests of soybeans, citrus and vegetables. At present, it is one of the few nematicides registered on vegetables in my country, especially suitable for the production of pollution-free vegetables. Thiazophos is a new type of high-efficiency and low-toxicity nematicide with contact killing and systemic conduction properties, which can effectively prevent nematodes from...
