Description
Technical Field
The invention relates to the technical field of pesticides, in particular to a weeding composition containing metamifop, cyhalofop-butyl and pretilachlor.
Background
The oxazoxamide is an aroxyphenoxy propionic acid systemic conduction type herbicide for preventing and killing annual grassy weeds, and the action mechanism of the oxazoxamide is an acetyl coenzyme A carboxylase (ACCase) inhibitor, so that the synthesis of plant fatty acid can be inhibited. Is used for preventing and killing barnyard grass, moleplant seed and other gramineous weeds in paddy field (direct seeding) stem and leaf treatment. The product is absorbed by stem and leaf, and is transmitted to growth point via vascular bundle to achieve weeding effect.
Cyhalofop-butyl is an aryloxyphenoxypropionic acid systemic conductivity herbicide that leads to weed death by disrupting cell division. The rice of various cultivation modes can be used. Can prevent and remove various annual grassy weeds such as barnyard grass, moleplant seed, crabgrass and the like.
Pretilachlor is an amide selective herbicide. The effective components can be absorbed by plant hypocotyl, mesocotyl and coleoptile, and the root is slightly absorbed, which directly interfere with protein synthesis in weed body and have indirect influence on photosynthesis and respiration. The damaged weed seedlings twist, primary leaves are difficult to stretch out, the leaf color turns dark green, and the growth stops until death.
In the prior art, no related literature report exists on the compounding of oxadiazon, cyhalofop-butyl and pretilachlor. In addition, the herbicide is easy to cause the generation of weed drug resistance after long-term single use, causes environmental pollution, and the search for a synergistic composition capable of improving the weeding effect and reducing the application dosage of the active ingredients is the research and development focus of a plurality of domestic pesticide companies.
