Use

Soil. 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
