In 1990 sulcotrione was introduced for post- emergence weed control in corn. Isoxaflutole opened the market more broadly for HPPD inhibitors when it was introduced in 1996 for corn and sugarcane, and for use as a pre-emergence herbicide that could control broadleaf weeds as did sulcotrione, but also additional grass weeds.
The triketone herbicides were found to be effective on a wide range of commercially-important weed species and to have both pre- and post-emergence activity. [9] Mesotrione was chosen for development (by Zeneca Agrochemicals under the code number ZA1296) because it controls a wide range of broad-leaved weeds that compete with maize and can also suppress some annual grass weeds that may be ...
Herbicide options are limited for these minor crops, particularly in the vegetable sector. [4] Long-term field studies performed by the German government and institutions together with farmers call pendimethalin efficient for controlling blackgrass, regarding weed control efficacy, crop yield, treatment costs and environmental impact.

Under aerobic conditions in soils or pure cultures, products of bromoxynil degradation often retain the original bromine groups. The herbicide, and one of its common degradation products (3,5-dibromo-4-hydroxybenzoic acid) have been shown to undergo metabolic reductive dehalogenation by the microorganism Desulfitobacterium chlororespirans.
