Embodiment 1

[0021] This embodiment discloses an environmentally friendly and residue-free herbicide, the raw materials of which include:

[0022] Sodium chlorate 60%, sodium bicarbonate 15%, kaolin 14.5%, white carbon black 5%, wetting agent 0.2%, dispersant 0.2%, binder 0.1%, stabilizer 5%.

[0023] This embodiment also discloses a preparation method of an environmentally friendly non-residue herbicide, comprising the following steps:

[0024] S1. Add sodium chlorate, sodium bicarbonate, kaolin, white carbon black, wetting agent, dispersant, binder, and stabilizer to the mixer in proportion, and stir evenly. The speed of the mixer is 200-1000r / min , the stirring time is 2-10 minutes;

[0025] S2. After the raw materials are mixed evenly, granulation is carried out, and the particle size of the granulation is 300-3000 μm;

[0026] S3. Sieve according to the particle size of the granulation, and classify and pack.

Abstract

The invention discloses an environment-friendly residue-free sterilant herbicide and a preparation method thereof. The environment-friendly residue-free sterilant herbicide is prepared from the following raw materials: 25-60% of sodium chlorate, 15-36% of sodium bicarbonate, 10-50% of kaolin, 3-5% of white carbon black, 0.1-0.9% of a wetting agent, 0.1-0.9% of a dispersing agent, 0.1-0.9% of an adhesive and 2-5% of a stabilizer. The preparation method comprises the steps of mixing, stirring, granulating and the like. The environment-friendly residue-free sterilant herbicide has the characteristics of high universality, quick effect, good effect, wide service time, environmental friendliness and the like, the effect can be realized in one week at the soonest, the lasting period of the environment-friendly residue-free sterilant herbicide is 2 months at most, and the crops can be planted after 3 months.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an environmentally friendly non-residue herbicide and a preparation method thereof. Background technique [0002] With the rapid development of modern agriculture, in order to ensure the output of crops, people use more and more pesticides, and the damage to the environment, humans and animals caused by pesticide residues is also increasing. In recent years, agricultural developed countries represented by the European Union are gradually banning medium and high-toxic pesticides, as well as pesticides that may cause adverse effects on the environment and ecology. Herbicide is the most used pesticide product in the world, accounting for about 50% of the pesticide usage. Global herbicides have problems such as large usage, few varieties, and slow development of new products. As a result, existing products cannot be banned even though they may cause cancer and affect the ecologic...
