Abstract
The invention provides a prometryn and alachlor binary complex herbicide and a preparation method thereof. The herbicide comprises the following components by mass: 10-35% of prometryn, 5-30% of alachlor, 5-15% of synergist, 8-20% of emulsifier and the balance solvent. The preparation method comprises the following steps: mixing and stirring the prometryn and the solvent according to the mass ratio; mixing and stirring the alachlor and the solvent; mixing and stirring the mixtures; adding the emulsifier together with the synergist to a reaction kettle to be stirred for 10-15min; then adding the balance solvent and stirring the mixture for 20-30min; and then carrying out standing, filtering, filling and sampling analysis, thus obtaining the finished product. The herbicide has high efficiency and broad spectrum, is used for soil spraying before sowing such crops as soy beans, tobaccos, chillies, melon and fruit, vegetables and the like, can realize that the crops are free from weeds in the whole growth period through one-time application of 80-120g per mu and has application cost 29.7-32.8% lower than that of the single prometryn or alachlor respectively.
