Abstract
The invention relates to a binary herbicide prepared by compounding oxyfluorfen with fluazifop-butyl and a preparation method thereof. The herbicide consists of the following components in percentage by mass: 3 to 10 percent of oxyfluorfen, 8 to 20 percent of fluazifop-butyl, 5 to 15 percent of surfactant, 6 to 20 percent of emulsifier and the balance of solvent. The preparation method comprises the following steps of: adding the solvent into the oxyfluorfen for mixing and stirring; adding the solvent into the fluazifop-butyl for mixing and stirring; mixing and stirring; adding the emulsifier and the surfactant into a reaction kettle, stirring for 10 to 15 minutes; adding the rest of solvent and stirring for 20 to 30 minutes; and standing, filtering, filling and performing sampling analysis to obtain a finished product. The herbicide is a high-efficiency broad-spectrum herbicide, and is used for removing 4 to 6 leaves period of weeds in a tea garden, a fruit orchard and a forestry nursery, and for crops such as grape, tobacco, cabbage, chilli, potato, sweet potato, soybean, flax, rubber and the like; after 45 to 55g of herbicide is applied to each mu at one time, the weeds can be completely removed in the whole growth period of the crops; and the application cost is respectively 29.8 to 30.6 percent lower than that of the oxyfluorfen and the fluazifop-butyl which are separately applied.
