2-Methoxy-3,6-dichlorobenzoic

Plant Dicamba is hydrolyzed in wheat and Kentucky bluegrass plants to 5-hydroxy-2-methoxy-3,6-dichlorobenzoic acid and 3,6-dichlorosalicylic acid at yields of 90 and 5%, respectively. The remaining 5% was unreacted dicamba (Broadhurst et al., 1966). Dicamba was absorbed from treated soils, translocated in corn plants and then converted to...

Plants. Degradation rate varies greatly with species. In wheat, the major metabolite is 5-hydroxy-2-methoxy-3,6-dichlorobenzoic acid, while 3,6-dichlorosalicylic acid is also a metabolite... 

Loss and detoxification of dicamba from treated plants occur by exudation through the roots and leaves and by metabolism in the plant. The main metabolite of dicamba is 5-hydroxy-2-methoxy-3,6-dichlorobenzoic acid, which forms conjugates (Broadhurst et ai, 1966 Chang and Van den Born, 1971). Dicamba is mobile in the soil, so its leaching depends on seasonal precipitation. It is readily metabolised by microorganisms in the soil. The major metabolite is 3,6-dichloro-salicylic acid (Harris, 1967). 

Other important members of synthetic auxins include 2,3,6-trichlOrobenzoic acid and 2-methoxy-3,6-dichlorobenzoic acid in the benzoic acid group and a-naphthoxyacetic acid and 4-amino-3,5,6-trichloropicolinic acid in the naphthoxy acid group.
