Especially in lawns sown in late spring, the damage of weeds is very serious. Many of the lands have to be destroyed due to the damage of weeds, resulting in serious economic losses. The main weeds that severely harm spring turfgrass in spring in the northern regions are: monocotyledonous weeds such as crabgrass, barnyardgrass, goosegrass and green foxtail, and dicotyledonous weeds such as oak and amaranth, among which monocotyledonous weeds are the most dangerous. , is the main factor causing the destruction of the lawn.

Due to the close relationship between monocotyledonous weeds and turfgrass, there is a certain degree of difficulty in the selection of pharmaceutical agents. After seven years of intensive research, the Weed Research Group of the Plant Protection and Environmental Protection Institute of the Beijing Academy of Agriculture and Forestry Sciences has screened out lawn turfgrass herbicides that are effective against turfgrass and effective against annual weeds, based on a large number of indoor and field experiments. "Wet powder. The drug can be used on lawns grown on grasses such as bluegrass, tall fescue, ryegrass and zoysiagrass.
