Problems solved by technology

[0002] China is a large agricultural country. In the process of crop production, a large number of weeds are prone to appear. Manual treatment is time-consuming and laborious, and it cannot remove weeds from the roots very well. It is easy to relapse. Herbicides are a necessary step in modern production. Existing weeding Most of the pesticides are destructive and highly toxic. In addition to effective weeding, they also cause certain damage to crops, are absorbed by the soil, change the soil texture, are not easy to degrade, and pollute the environment.

Abstract

The invention relates to an environmental-friendly weed killer and a preparation method thereof. The environmental-friendly weed killer comprises the following components in parts by weight: 10-15 parts of 2,6-dinitro-N,N-di-n-propyl-4-trifluoromethyl phenylamine, 3-8 parts of acetochlor, 4-6 parts of alachlor, 3-5 parts of pendimethalin, 6-8 parts of metolachlor, 7-10 parts of propisochlor, 3-6 parts of sorbitol, 10-12 parts of atrazine, 5-10 parts of nicosulfuron, 20-30 parts of alcohol, 3-5 parts of citric acid and 3-6 parts of allicin. According to the environmental-friendly weed killer, materials are easily available, the cost and the toxicity are low, the weed killer can be graded, the weed killing effect is fast, the weed killer can penetrate into soil with rainfall, deep-rooting weeds can be effectively killed without damage to growth of crops, the weed killer can be degraded without polluting the environment and damaging soil nutrients, the stability is strong, oxidation is difficult, the emulsifying effect is good, full fusion of water and oil can be guaranteed and the lasting time of the weed-killing effect is long.
