Problems solved by technology

However, paraquat is extremely toxic to humans, and there is no specific antidote, and the mortality rate of oral poisoning can reach more than 90%.
[0008] As mentioned above, the existing herbicides still have various threats to people and the environment, and they are far from reaching the desired goal.

Embodiment 1

[0040] A kind of herbicide, each component comprises by weight percentage in the described herbicide:

[0041] Metolachlor 14%,

[0042] Atrazine 35%,

[0043] Glyphosate 28%,

[0044] SOPA-II 5%,

[0045] Montmorillonite 14%,

[0046] Potassium nitrate 4%.

[0047] Wherein, the preparation method of the herbicide is as follows: first, weigh each raw material according to the above ratio, then crush and grind the montmorillonite, pass through a 120-mesh sieve, and continue to grind and sieve the sieve; dissolve potassium nitrate in deionized water, then filtered to remove impurities, and then evaporated at 100 ° C until no solid precipitated, dried and ground the precipitated solid to obtain potassium nitrate powder; then metolachlor, atrazine Add zinc and glyphosate to SOPA-II, stir for 30 minutes to obtain a viscous slurry; finally add montmorillonite powder and potassium nitrate powder to the slurry, and continue stirring for 30 minutes to obtain the herbicide.

Abstract

The invention discloses a weedicide. The weedicide comprises the following components in percent by mass: 8-20% of metolachlor, 30-60% of atrazine, 20-50% of glyphosate, 3-8% of SOPA-II, 10-30% of montmorillonite and 3-5% of potassium nitrate. Compared with the prior art, the weedicide disclosed by the invention has the advantages as follows: through a proper proportion and less using amount of the glyphosate, the weedicide has a relatively good weedicidal effect; when the weedicide is used, the residue is low and harm to people and livestock is low; in addition, through use of the SOPA-II andthe montmorillonite, the effect of the weedicide is further improved; the potassium nitrate supplying N and K elements is introduced, so that the weedicide can fertile a land and nourish crops; and the weedicide disclosed by the invention has small environment pollution and a good effect, also contributes to healthy growth of the crops and has a wide application prospect.

Description

technical field [0001] The invention relates to a pesticide, in particular to a herbicide and a preparation method thereof. Background technique [0002] As an important guarantee for agricultural development, pesticides play an important role in the social economy. As an important aspect of agriculture, herbicides develop more rapidly. No matter in terms of production capacity, output and variety, their growth rate is greater than that of other types of pesticides. . [0003] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. [0004] There are nearly a hundred herbicide products in the pesticide market in my country, but among them, they are widely used. The three most commonly used are glyphosate, acetochlor, and paraquat. [0005] Glyphosate is a non-selective systemic herbicide for stem and leaf treatment. It was discovered in 1970 by Monsanto chemist John...
