Definition of trifluralin:
Trifluralin is a herbicide used to control a wide spectrum of annual grasses and broadleaf weeds in agriculture, horticulture, viticulture, amenity and home garden. The major crops it is used on are oilseed rape and sunflowers and, to a lesser extent, cotton and cereals.[1]
This is the common definition for trifluralin, other definitions can be discussed in the article

Notes
Approximately 3200 tonnes of active substance trifluralin annually are used in the EU (including accession countries). Trifluralin is presently authorised for use in Belgium, Finland, France, Germany, Ireland, Portugal, Spain and the United Kingdom.
Significant amounts may evaporate into the air from the agricultural use (estimated 64 t/y for total Europe), but photochemical oxidative degradation will rapidly decrease this load before it can be transported far beyond the coasts. Trifluralin has a high affinity towards organic matter and will therefore be found mostly in sediment and bound to suspended particles. Because of this high affinity to sediment, it's considered unlikely that large amounts of trifluralin enter the marine environment through run off from application areas.
Concentrations of trifluralin in both the North Sea and the Baltic sea are bellow 0,06 ng/l.
