Abstract
The invention discloses a herbicidal composition containing cyclosulfamuron, and application thereof, wherein the herbicidal composition comprises an active component A and an active component B, theactive component A is cyclosulfamuron, the active component B is any one selected from pyribenzoxim and pyrazosulfuron-ethyl, and the mass ratio of the active component A to the active component B ofthe composition is 1:50-50:1. According to the invention, the composition can be prepared into agriculturally allowable dosage forms, preferably missible oil, a suspending agent, an emulsion in water,wettable powder, water dispersible granules and a dispersible oil suspending agent; and the herbicidal composition is reasonable in component and good in weeding effect in a paddy field, the activityof the herbicidal composition is not simple superposition of all components, and compared with the existing single preparation, the herbicidal composition has the advantages of being low in dosage, wide in weed control spectrum, safe to crops and the like.
Description
technical field [0001] The invention relates to a herbicidal composition and its application, in particular to a herbicidal composition containing cyclasulfuron and its application, and belongs to the technical field of pesticide compounding. Background technique [0002] Cyclosulfamuron (Cyclosulfamuron) CAS number is 136849-15-5, belongs to sulfonylurea herbicides, and is an inhibitor of acetolactate synthase (ALS). Cyclosulfuron can be absorbed by the roots and leaves of weeds, and conduct in the plant body. The weeds stop growing, the leaves chlorosis, and usually die completely after a few weeks. The herbicide has high efficiency and low toxicity, and is mainly used for controlling annual and perennial broad-leaved weeds and sedge weeds. Although it is active against grass weeds, it cannot be completely controlled. It is mainly used for pre-emergence and post-emergence application to control broad-leaved weeds such as rice, wheat, and barley. [0003] Pyribenzoxim (Py...
