Herbicide mixture and weeding microemulsion special for rhizoma atractylodis

Abstract

The invention provides a herbicide mixture and weeding microemulsion special for rhizoma atractylodis. The herbicide mixture or the weeding microemulsion comprises the following raw materials: effective active components, a surfactant, dioctyl sulfosuccinate sodium salt as an emulsifier, ethyl alcohol as a co-solvent, water, propylene glycol as an antifreezing agent and piperonyl butoxide as a potentiator, wherein the effective active components comprise saflufenacil, metolachlor, thifensulfuron methyl and imazaquin; the surfactant comprises one or more of octyl phenol polyoxyethylene ether sulfonate, fatty alcohol polyoxyethylene ether and naphthalene sulfonate formaldehyde condensate. The herbicide mixture and the weeding microemulsion have a quite good effect of eliminating rhizoma atractylodis weeds, and are safe, efficient, good in chemical degradation effect and small in residue quantity; the microemulsion can be used for eliminating weeds better through adopting the surfactant provided by the invention.

Problems solved by technology

In addition, herbicide residues in the soil affect the persistence of herbicides and the safety of the environment

From the aspect of weed control, herbicides should have a certain residual period. If the residual period is too short, the weeding effect will not be good, but if the residual period is too long, it will cause phytotoxicity to the recommended crops.

However, from an environmental point of view, the shorter the residual period of herbicides, the better. Herbicides are too stable, not easy to degrade, and have a large amount of residues in the environment, which will cause environmental pollution.
