Description
Napropamide, a soil herbicide, is a colorless crystalline solid in its pure form, with the technical form appearing as a tan to brown solid. It can be applied either by spraying on the surface or incorporating it into the soil. Napropamide is primarily used for weed control management, making it a valuable tool in agricultural practices.
Uses
Used in Agriculture:
Napropamide is used as a herbicide for pre-emergence control of annual grasses and certain broad-leaved weeds in various crops. It is a General Use Pesticide (GUP) that is compatible with many other fungicides and herbicides, providing effective weed control management.
Napropamide is used as a pesticide in the following application industries:
1. Mint:
Napropamide is used as a herbicide for controlling broadleaf weeds and annual grasses in mint crops, ensuring healthy plant growth and increased yield.
2. Orchards:
In orchards, Napropamide is used as a pre-emergence herbicide to control weeds that may compete with fruit trees for nutrients and space, promoting better fruit production.
3. Small Fruits:
Napropamide is employed as a herbicide in small fruit crops, such as strawberries and raspberries, to manage weed growth and improve crop quality.
4. Tobacco:
Napropamide is used as a herbicide in tobacco farming to control weeds, reducing competition for resources and enhancing tobacco plant health.
5. Turf:
In turf management, Napropamide is used as a herbicide to control unwanted grasses and broadleaf weeds, maintaining a clean and uniform appearance.
6. Vegetable Crops:
Napropamide is utilized as a herbicide in vegetable crops to control weeds, allowing for better growth and higher yields of vegetables.
7. Ornamentals:
In the cultivation of ornamental plants, Napropamide is used as a herbicide to manage weed growth, ensuring the plants remain healthy and visually appealing.
8. Oil Seed Rape, Fruit Bushes, Vines, Sunflowers, and Olives:
Napropamide is also used as a herbicide in these crops to control weeds and promote healthy plant growth, leading to increased productivity and better quality produce.

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.
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

Incompatibilities
Slowly hydrolyzes in water, releasing
ammonia and forming acetate salt.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 15299-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,9 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 15299-99:
(7*1)+(6*5)+(5*2)+(4*9)+(3*9)+(2*9)+(1*9)=137
137 % 10 = 7
So 15299-99-7 is a valid CAS Registry Number.
