The invention belongs to the field of pesticides and discloses a herbicidal composition containing dithiopyr and 2,4-dichlorophenoxy acetic acid and application thereof. The herbicide takes dithiopyr and 2,4-dichlorophenoxy acetic acid as the main active ingredients, wherein the mass ratio of dithiopyr to 2,4-dichlorophenoxy acetic acid is (1-70):(1-80) and dithiopyr and 2,4-dichlorophenoxy acetic acid 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 herbicidal spectrum and long efficacy duration and does no harm to the lawns and the aftercrops on the premise of improving the drug effect.

The invention discloses a compound herbicidal composition containing monopyrimsulfonate and its application. The active ingredients are monopyrimsulfonate and isoproturon. The binary herbicidal composition of the present invention is compounded by using monosulfanilate and isoproturon with different herbicidal spectrums and complementary advantages and disadvantages. The combined use of the two delays the generation of drug resistance of crops and has ideal application effects: killing It has the advantages of wide grass spectrum, quick effect, high efficiency, low toxicity, low residue, safety and environmental protection, which can reduce the dosage of pesticides, reduce pesticide residues, good environmental compatibility, and safety for humans and animals. It is a high-quality chemical herbicide for wheat crops. As the content of active ingredients is reduced, the pesticide residues are reduced on the premise of improving the efficacy of the pesticide, and the safety of wheat and subsequent crops is higher, and the possibility of residual poisoning of pesticides to humans and animals is avoided.

The invention discloses a mixed herbicide containing pyrasulfotole and fluoroglycofen. The herbicide takes pyrasulfotole and fluoroglycofen as main active ingredients, wherein the mass ratio of pyrasulfotole to fluoroglycofen is (1-68) to (1-68). The mixed herbicide has the advantages of broad spectrum, quick action, high efficiency, low toxicity, safety, environment friendliness, and the like when being applied to post-emergence weed control in wheat fields.

The invention belongs to the field of pesticides and discloses a herbicidal composition containing diflufenzopyr, nicosulfuron and dicamba and application of the herbicidal composition. The herbicidal composition takes diflufenzopyr, nicosulfuron and dicamba as the main active ingredients, wherein diflufenzopyr, nicosulfuron and dicamba account for 10-85% of the herbicidal composition by mass and the mass ratio of diflufenzopyr to nicosulfuron to dicamba is (1-65):(0.5-75):(1-80). The herbicidal composition can be applied to preparing the herbicides for controlling the postemergence weeds in the cornfield and especially has obvious effect on preparing the herbicides for controlling various grass and broadleaf weeds in the cornfield. Compared with the single agent, the herbicidal composition reduces the drug dose, delays weed resistance, has wide herbicidal spectrum and long efficacy duration and does no harm to the corn and the aftercrops on the premise of improving the drug effect.
