4results about How to "Good weeding effect" patented technology

The invention discloses a nicosulfuron-containing herbicidal composition and application thereof. The herbicidal composition is prepared from the following components: nicosulfuron, amicarbazone, and dimethyltetrachloroisooctyl ester as well as a dispersant, an emulsifier, a wetting agent, a thickening agent, an antifreeze, and a dispersion medium, wherein the dosage form belongs to a dispersed oil suspension agent. Through the combination of the three active ingredients, the herbicidal composition has an obvious synergistic effect, the use amount of pesticides is reduced, the cost and environmental pollution are reduced, the drug resistance of corn field weeds can be delayed by the application of the composition, and the control spectrum is expanded.

This invention belongs to the field of agricultural herbicides and provides a photosynthetic inhibitor herbicidal composition comprising 5-aminolevulinic acid, malondialdehyde, and a herbicidal active ingredient. The herbicidal active ingredient is selected from one or a combination of several herbicides selected from acetolactate synthase inhibitors, photosynthetic system II inhibitors, or protoporphyrinogen oxidase (PPO) inhibitors. This invention utilizes the synergistic effect of 5-aminolevulinic acid, malondialdehyde, and a specific type of herbicidal active ingredient to effectively enhance the efficacy of the herbicidal active ingredient, enabling rapid and thorough weed control.

This invention provides a herbicidal composition containing benzoxam, wherein the active ingredients comprise active ingredient A and active ingredient B; the mass ratio of active ingredient A to active ingredient B is 1:10-10:1; active ingredient A is benzoxam, and active ingredient B is one or both of pyrimethanil and propyzoxystrobin. This herbicidal composition exhibits a significant synergistic effect, significantly improving the herbicidal efficacy of the herbicide, reducing the dosage required, slowing the development of pesticide resistance, and mitigating environmental pollution. This herbicidal composition can be used for weed control in non-cultivated land, demonstrating excellent herbicidal efficacy.

The application discloses a herbicidal composition containing flumeturon and application thereof, and the composition contains active ingredient A and active ingredient B, wherein the active ingredient A is flumeturon, and the active ingredient B is bispyribac. The mass ratio of the active ingredient A to the active ingredient B is 1:50-50:1. The application is reasonable in component, has good herbicidal effect in a rice field, and the activity and the herbicidal effect are not simple superposition of each component. Compared with existing single preparation, the application has the characteristics of significant herbicidal effect, low drug dosage, wide weed spectrum and good safety to crops.
