Abstract

The invention discloses an efficient herbicide and a preparation method thereof. The efficient herbicide comprises the following raw materials in parts by weight: 10-20 parts of bensulfuron methyl, 20-30 parts of sodium hexametaphosphate, 20-30 parts of 1,4-diphenyl acetophenone, 10-15 parts of ammonium nitrate, 40-50 parts of urea, 10-18 parts of citric acid, 20-40 parts of sodium nitrate, 23-30 parts of dioxymethane, 10-25 parts of methyl ethyl ketone, 27-30 parts of butyl acetate, 20-50 parts of methyl isopropyl ketone, 5-10 parts of a surfactant and 40-80 parts of water. The preparation method comprises the following steps: heating thebensulfuron methyl, the sodium hexametaphosphate, the 1,4-diphenyl acetophenone, the ammonium nitrate, the urea, the citric acid, the sodium nitrate, the surfactant and the water to react; adding residual components; and continually heating and reacting, and cooling. The efficient herbicide disclosed by the invention has high activity and good activity and has a serious growth inhibition effect on weeds.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a high-efficiency herbicide and a preparation method thereof. Background technique [0002] Herbicides, also known as herbicides, are a class of substances used to destroy or inhibit the growth of plants. The action is affected by three factors: herbicide, plant and environmental conditions. According to the function, it can be divided into killing and selective herbicides, and the commonly used varieties are organic compounds. It can be widely used to prevent and control harmful plants such as weeds, shrubs, and trees in farmland, orchards, flower nurseries, grasslands and non-cultivated land, railway lines, rivers, reservoirs, warehouses, etc. Although existing herbicides have a certain inhibitory effect on weeds, the inhibitory effect is not good enough. Contents of the invention [0003] The object of the present invention is to provide a herbicide with high efficiency and v...
