The application provides a non-
cultivated land herbicide composition and application thereof, and belongs to the technical field of non-
cultivated land herbicides. The effective component of the non-
cultivated land herbicide composition comprises
hexazinone, diuron, 2,4-D and
glyphosate; further, the non-cultivated land herbicide composition further comprises a synergist. The non-cultivated land herbicide composition provided by the application has the advantages of high efficiency,
low toxicity, broad-spectrum eradication, rapid effect, long persistence, simple operation and easy implementation; the addition of the synergist can improve the penetration, adhesion and rainwater
erosion resistance of the herbicide to
weed stems and leaves and soil, improve the herbicidal
efficacy and reduce the
occurrence probability of
phytotoxicity; further, the synergist can accelerate the effect speed of the herbicide and improve the utilization efficiency of the herbicide. The application can overcome the shortcomings of the development of
weed resistance caused by the long-term use of conventional single herbicide or
binary compound preparation, make up for the deficiencies of the existing non-cultivated land herbicides and guarantee the efficient and safe control of non-cultivated land weeds.
