Abstract

The invention discloses a rimsulfuron.haloxyfop-P-methyl water dispersible granule as a weed killer and a preparation method thereof, belonging to the technical field of weeding for plant protection. The rimsulfuron.haloxyfop-P-methyl water dispersible granule comprises the following components in percentage by mass: 10-20% of rimsulfuron, 5-10% of haloxyfop-P-methyl, 3-5% of wetting agent K12, 5-8% of ketamine as a dispersing agent, 5-7% of ammonium sulfate as a disintegrating agent, 5-10% of white carbon black as a carrier and the balance of light calcium carbonate as packing. The rimsulfuron.haloxyfop-P-methyl water dispersible granule can be used for preventing and controlling grassy weeds such as crab grass, moleplant seeds, annual broad-leaved weeds such as crowndaisy chrysanthemum, piemarker and the like and cyperaceae weeds such as cyperus rotundus and the like in a tobacco field. The rimsulfuron.haloxyfop-P-methyl water dispersible granule has the advantages of no need of specific equipment for a process, simplicity in operation, low preparation cost, little pollution to the environment, safety in storage and transportation, stable preventing effect and the like.

Description

technical field [0001] The invention relates to a herbicide, in particular to a water-dispersible granule compounded with rimsulfuron-methyl and high-efficiency haloxyfop-pylene and a preparation method thereof. Background technique [0002] With the enhancement of human awareness of environmental protection, water-based, granular, multi-functional, labor-saving, safe and environmentally friendly formulations have become the development direction of pesticide formulations at home and abroad. Granulation of solid preparations refers to replacing powder or wettable powder with water-dispersible granules, effervescent tablets, etc. Water-based liquid preparation refers to the preparation of pesticide dosage forms with water as the medium, such as water emulsion, microemulsion, and water suspension. [0003] Pesticide water-dispersible granules are considered to be an important direction for the development of pesticide formulations because of their good safety, low environment...
