Napropamide Usage And Synthesis
  • Chemical PropertiesColorless crystalline solid (pure). Technical form is tan to brown solid.
  • UsesHerbicide.
  • UsesPreemergence control of annual grasses and certain broad-leaved weeds in mint, orchards, small fruits, tobacco, turf, vegetable crops and ornamentals
  • HazardLow toxicity.
  • Agricultural UsesHerbicide: A General Use Pesticide (GUP) that is compatible with many other fungicides and herbicides. Used to control broadleaf weeds and annual grasses on a variety of crops including vegetables, fruit trees, fruit bushes, oil seed rape, vines, sunflowers, olives, tobacco and mint.
  • Trade nameCOLZOR TRIO® (dimethachlor + napropamide + clomazone); DEVRINOL®; NAPROGUARD®; WAYLAY®; R-7165®
  • Potential ExposureA amide/alkanamide general use pesticide and herbicide that is compatible with many other fungicides and herbicides. Used to control broadleaf weeds and annual grasses on a variety of crops including vegetables, fruit trees; fruit bushes, oil seed rape, vines, sunflowers, olives, tobacco, and mint.
  • Environmental FateSoil. Degrades slowly in soil to 1-naphthol, 1,4-naphthoquinone, 2-(a-naphthoxy)-Nethylpropionamide and 2-(a-naphthoxy)propionamide (Hartley and Kidd, 1987). In moist loam or sandy-loam soils at 70–90°C, the half-life was 8–12 weeks. However, the persistence may be as long as 9 months under conditions where microbial growth is limited (Ashton and Monaco, 1991). Gerstl and Yaron (1983a) reported that the half-life of napropamide in soil can range from 34 to 201 days depending upon the organic matter content, soil texture, soil moisture content and analytical method.
    Plant. Rapidly metabolized in tomatoes and several fruit trees forming the watersoluble hexose conjugates of 4-hydroxynapropamide (Humburg et al., 1989; Ashton and Monaco, 1991).
    Photolytic. Napropamide decomposes under UV light. Under laboratory conditions, irradiation of an aerated aqueous solution with UV light gave 2-hydroxypropananilide, 2- propenanilide and pyruvinanilide as the major products. Minor photoproducts i

  • IncompatibilitiesSlowly hydrolyzes in water, releasing ammonia and forming acetate salt.
  • Waste DisposalSmall amounts may be destroyed by alkaline hydrolysis. Admixture with alkali can be followed by soil burial. Larger quantities can be disposed of by incineration in admixture with acetone or xylene and using effluent gas scrubbing.
