Napropamide is an acetamide herbicide. It was first sold under the trade name Devrinol,2 and was first manufactured in 1969.3 It is widely used in the European Union,1 and in Australia.4

"Devrinol 50" is a wettable powder containing 50% napropamide.5

Napropamide's mode of action is unknown, therefore the HRAC classification system calls it equivalently Group Z or Group 0, although it was formerly classified as Group K (Group K3 or 15).6

Chemistry

Napropamide inhibits root growth. It is used against annual grasses and broadleaf weeds.2 The d-isomer is noted as being significantly more effective than the racemic mixture against certain weeds.3 Its formula is C17H21NO2.2

Tradenames

Napropamide has been sold as "Devrinol", "Jouster" and "Naprop".51
