Abstract
The invention aims to liberate manual labor, and provides a rice herbicide, comprising potassium hydroxide, p-nitrchlorobenzene, phenol, chlorine and sodium sulfite. The invention has the advantage that weed killing at the germination period of weeds has little injury on rice, and does not affect the growth and development of rice.
Description
Technical field
The present invention relates to crops weed killer herbicide, is rice herbicide specifically.
Background technology

Summary of the invention
The object of the invention is a kind of liberation hand labor, provide a kind of effective weed killer herbicide, technical scheme is: rice herbicide, it is characterized in that formula constituent percentage by weight is: potassium hydroxide 12%, paranitrochlorobenzene 14%, phenol 22%, chlorine 50%, sodium sulphite 2%.
Advantage of the present invention is: kill weeds at weeds germination period, little to rice drug misadventuring, does not affect rice growth.
Embodiment
By formula weight percent, component benzoic acid is dropped in chlorination reaction pot, be heated to 60-65 degree and be warming up to 70 degree by chlorine, potassium hydroxide solution is added again after adding sodium sulfite solution process after having reacted, be warming up to 120 degree after salify and add nitro-chlorobenzene, be warming up to 230 degree, be incubated 10 hours, be uniformly mixed and cool.
