Abstract

The invention relates to herbicide special for a sugarcane field and a preparation method of the herbicide, and belongs to the technical field of pesticide preparation. The herbicide is prepared from the following raw materials in parts by weight: 20 to 26 parts of acetochlor, 10 to 18 parts of diuron, 8 to 16 parts of hexazinone, 7 to 15 parts of ethoxysulfuron, 3 to 7 parts of topramezone and 1 to 5 parts of an auxiliary. The preparation method comprises the following steps: mixing the raw materials, performing stirring reaction at the stirring speed of 260 to 300r / min for 40 to 50 minutes, and adjusting the pH value of the reaction to11 to 12; heating to 40 to 46 DEG C at the heating speed of 5 to 10 DEG C / min, keeping the temperature for 45 minutes, cooling to normal temperature, thereby obtaining a finished product. The herbicide is obvious in effect; an ideal effect can be achieved by one-time herbicide use, and the preventing effect is 95 percent or more; the herbicide is safe to sugarcanes and environmentally friendly; the preparation technology is simple and low in cost.

Description

technical field [0001] The invention relates to a herbicide and a preparation method thereof, in particular to a special herbicide for sugarcane fields and a preparation method thereof, and belongs to the technical field of pesticide preparation. Background technique [0002] Sugarcane, (scientific name: Saccharumofficinarum) is a perennial tall solid herb of the genus Saccharum. The rhizome is thick and well developed. Stem height 3-5 (-6) meters. China Taiwan, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan and other southern tropical regions are widely planted. Sugarcane is suitable for planting in places with fertile soil, sufficient sunlight, and large temperature differences between winter and summer. Sugar cane is a temperate and tropical crop that is used as a raw material for the manufacture of sugar and for ethanol as an energy substitute. There are more than 100 countries producing sugar cane in the world, and the largest sugar cane producing countries are...
