Abstract
The invention discloses a herbicide composition as well as a preparation method and application thereof. The herbicide composition is a three-component herbicide composition comprising nicosulfuron, atrazine and fiuroxypyr used as active components, wherein the proportion by weight of the nicosulfuron to the atrazine to the fiuroxypyr is 1-10:5-50:1-20. The preparation method of the composition comprises the following steps of: firstly weighing primary medicines and auxiliary agents, then adding the nicosulfuron as the primary medicine, the atrazine as the primary medicine, the fiuroxypyr as the primary medicine, the auxiliary agents and a solvent into a ball mill for milling for 2-3 hours, transferring into a sand mill for sanding for 3-4 hours, adding into a finished-product blending tank, sampling, analyzing and blending. The composition is suitable for preventing and removing in-field weeds and is particularly suitable for preventing and removing the weeds in corn fields. The herbicide composition can play the weeding effect within a short period of time and has good weeding effect, thereby the dosage of a herbicide is reduced.
