2,4-DB 500SC Herbicide is a member of the phenoxys group of herbicides and has distributors of cell growth as its mode of action. 2,4-DB is an inactive form of the phenoxy molecule and after spraying onto weeds, it must first be converted by the weeds into 2,4-D, then finally into the active 2,4-D acid.
For the most effective results, weeds must be actively growing. If 2,4-DB remains in the weed for a period of time as the inactive form because the weed is not growing, efficacy will be affected. Plants are usually actively growing when daytime temperatures are above 15 degrees Celsius and there are no frosts. Seedling clovers and medics do not have the ability to convert the 2,4-DB into the 2,4-D acid, however, as they mature, they develop the ability to do this which is why 2,4-DB is safest on young pasture species. Damage symptoms may increase after they reach the 8 leaf stage.
