Foreign name: Flumioxazin
Molecular formula: C19H15FN2O4
Molecular structure:
Pesticide characteristics:
Propargyl fluxamine is a herbicide absorbed by young shoots and leaves, and used as soil treatment can effectively control 1-year-old broadleaf weeds and some grass weeds, which are easily degraded in the environment and safe for stubble crops. Soybeans and peanuts are very resistant to it. Maize, wheat, barley, rice have moderate tolerance.
Scope:
It is suitable for crop fields such as soybean, peanut, and orchards to control 1-year-old broadleaf and some grass weeds.
Matters needing attention:
1. Post germination applica - tion of soybean is susceptible to drug damage, so it must be applied before the seedling.
2. Soil drying influences drug efficacy. Irrigation should be initiated before sowing and then applied.
3. In areas where grass weeds and broadleaf weeds are intermingled, they should be used in combination with herbi cides for the control of grass weeds and will do better.
4. Read the specific methods of use and precautions documented on the commodity label in detail.
Propargyl fl uoridoxamine is a very important enzyme in plant chlorophyll synthesis by inhibiting protoporphyrinogen oxidase (PPO), and the accumulation of protoporphyrin in sensitive plants after treatment leads to photosensitization and the bio oxidation of cell membrane lipids, resulting in irreversible damage to the function and structure of cell membranes, stem and leaf necrosis of sensitive weed stem and leaves after stem and leaf treatment, and death after sunlight irradiation; Buds of sensitive weeds were necrotic after soil treatment and died after brief sunlight exposure.
