Dichlobenil was reported to be more than 100 times more inhibitory than coumarin toward cellulose biosynthesis in two further cell wall synthesizing systems. In cotton fibers growing from in vitro cultured ovules, dichlobenil at a concentration of 10 fiM caused 80% inhibition of cellulose biosynthesis within 2-3 h the inhibition was reversed by removal of the herbicide.Micromolar concentrations were effective within 10 min of incubation, indicating that cellulose biosynthesis is a likely primary target for this herbicide. The action of dichlobenil is more specific for the )8-(1 — 4)-glucan synthesis of cellulose rather than noncellulosic )8-(l — 3)-glucan synthesis, which is less sensitive. In tobacco cells, specific inhibition of cellulose biosynthesis was apparent at 0.5-5.0/iM dichlobenil however, no inhibition of in u/tro j3-glucan synthesis in particulate membrane... 

Cotton fiber is formed during maturation. This includes not only cellulose biosynthesis, but also ordering of the cellulose macromolecules shaped as chains and formed by repetitive units consisting two P-D-glucose residues bound by glucosidic bonds. Among all plant fibers, cotton contains the maximum amount of cellulose (95-96%).
