Herbicide

Abstract

The invention discloses a herbicide. The herbicide is prepared from, by weight, 30-50 parts of water, 10-15 parts of acetic acid, 5-10 parts of anhydrous cupric sulfate, 1.1-1.5 parts of 2-methylphenol, 2-8 parts of ethylene glycol, 1-6 parts of acetone alcohol, 3-5 parts of formaldehyde solution, 15-25 parts of methanol and 1.2-1.8 parts of 3-methylphenol. A preparation method of the herbicide comprises the following steps that S1, a certain amount of the acetone alcohol is obtained by weight and put into a stirring machine containing water, and then stirring is conducted; S2, a certain amount of the methanol is obtained by weight and put into the stirrer, and then stirring is conducted to make the acetone alcohol in a stable state; S3, a certain amount of the formaldehyde solution, a certain amount of the ethylene glycol and a certain amount of the 3-methylphenol are obtained by weight and put into the stirrer, the temperature is adjusted to 25-30 DEG C, and then uniform stirring is conducted. According to the herbicide, all the raw materials can be well mixed, weeds can be effectively removed, the herbicide itself is free of toxicity and can be widely used.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide. Background technique [0002] As modern agricultural production puts forward higher requirements for the safe and reasonable use of herbicides, this requires enterprises to look forward, develop and innovate, and accelerate the development of efficient, safe, broad-spectrum, and environmentally friendly herbicide varieties that meet the actual needs of agriculture. Taking into account some small crops, injecting fresh vitality into the diversity of herbicide varieties. However, at present, my country's herbicides have few innovative products, slow update of active ingredients, unbalanced formulation development, serious homogeneity of product registration and other prominent problems. In addition, due to the long-term, excessive, repeated and unreasonable use of herbicides, the succession of weed communities, the increase in the proportion of difficult-to-control...

Problems solved by technology

However, at present, my country's herbicides have few innovative products, slow update of active ingredients, unbalanced development of dosage forms, serious homogeneity of product registration, and other prominent problems.

In addition, due to the long-term, excessive, repeated and unreasonable use of herbicides, the succession of weed communities, the increase in the proportion of difficult-to-control weeds, and the growing problem of weed resistance have become increasingly serious, and traditional herbicides have very strong Large toxicity, and long retention time in the soil, then many crops cannot be planted on the farmland in the second year, or the yield will be affected after planting, greatly affecting the work of farmers, and also increasing the cost of use
