Nitralin is a selective pre-emergent dinitroaniline herbicide[7] that is closely related to trifluralin, and released two years later in 1966.
It was used in the USA, France and Australia to control annual grasses and broad-leaved weeds, and was applied on vines, crops[8][9][10] and turf.
[12] On ryegrass meristems, nitralin suppressed elongation and made the roots wider.
[7] Shell sold technical grade nitralin at 94% purity for manufacturing purposes.
[18] At Johnsongrass control, nitralin and pendimethalin lost out to trifluralin and other dinitroaniline herbicides.
