Zusammenfassung:The invention belongs to the field of pesticides and discloses a herbicidal composition containing dithiopyr and picloram and application thereof. The herbicide takes dithiopyr and picloram as the main active ingredients, wherein the mass ratio of dithiopyr to picloram is (1-65):(1-80) and dithiopyr and picloram account for 10-85% of the herbicidal composition by mass. The herbicidal composition can be applied to preparing the herbicides for controlling postemergence weeds on the lawns and has obvious effect on preparing the herbicides for controlling the preemergence weeds on the built and planted lawns, especially the herbicides for controlling tall fescue and Kentucky bluegrass lawns. Compared with the single agent, the herbicidal composition delays weed resistance, has wide herbicidalspectrum and long efficacy duration and does no harm to the lawns and the aftercrops on the premise of improving the drug effect.
