Abstract

The invention provides a weed control composition containing ametryn, sulfentrazone and flazasulfuron and an application thereof, which relate to the weed control composition. The weed control composition comprises the ametryn, the sulfentrazone and the flazasulfuron which serve as active materials. The invention also relates to a method for disposing unwanted plants by using the weed control composition. The weed control composition contains the active materials which are the ametryn, sulfentrazone and flazasulfuron. According to the weed control composition, the weight ratio of the ametryn to the sulfentrazone is (30:1)-(1:30), the weight ratio of the ametryn or sulfentrazone to the flazasulfuron is (90:1)-(1:10), and the total weight of the ametryn, sulfentrazone and flazasulfuron accounts for 5-95% of the weight of the weed control composition. The weed control composition is mainly used for preventing and killing off weeds, especially cyperus rotundus in sugar crane farms, corn fields, citrus orchards and other places.

Description

Technical field [0001] The weeds that contain sulfurpania, sulfona, and ampiogenic sulfuron are involved.Active substance.The present invention also involves the method of using the method of unwillingness to use the weeding composition Background technique [0002] Protecting crops against weeds and other plants that suppress crop growth are repeated problems in agricultural management.In order to help solve these problems, researchers in the synthetic field of chemistry have produced a variety of chemicals and chemical preparations that are effective in preventing and controlling this kind of unnecessary growth.Many types of chemical herbicides are made public in the literature, and many types have been commercially available. [0003] In some cases, the weeding activity ingredients appear more effective than when the combination is applied. This phenomenon is called "synergistic role" because the combination shows such effectiveness or activity level.The effectiveness of the s...
