Potential Exposure
A 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.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions) if
breathing has stopped, and CPR if heart action has stopped.
Transfer promptly to a medical facility. When this chemical
has been swallowed, get medical attention. Give large
quantities of water and induce vomiting. Do not make an
unconscious person vomit. Do not induce vomiting when
formulations containing petroleum solvents are ingested.
Shipping
UN3082 Environmentally hazardous substances,
liquid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous
hazardous material, Technical Name Required
Incompatibilities
Slowly hydrolyzes in water, releasing
ammonia and forming acetate salt.
Chemical Properties
Colorless crystalline solid (pure). Technical
form is tan to brown solid.
Waste Disposal
Small 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.
Uses
Preemergence control of annual grasses and certain broad-leaved weeds in mint,
orchards, small fruits, tobacco, turf, vegetable crops and ornamentals
Definition
ChEBI: N,N-diethyl-2-(naphthalen-1-yloxy)propanamide is a monocarboxylic acid amide that is propanamide substituted by two ethyl groups at the nitrogen atom and a naphthalen-1-yloxy group at position 2. It is an aromatic ether, a monocarboxylic acid amide and a member of naphthalenes.
General Description
Napropamid is a soil herbicide, which can be either sprayed on the surface or incorporated.It can be mainly used for weed control management.
Agricultural Uses
Herbicide: 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.

Environmental Fate
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
