Molecular Structure:

Property:

The density of DICAMBA is 1.57,the melting point of DICAMBA is 87-108 șC. The water solubility of DICAMBA is 50g/100ml. Dicamba (3,6-dichloro-2-methoxybenzoic acid) is an organochlorine compound that is used as a herbicide. Brand names for formulations of this herbicide include Banvel, Oracle and Vanquish. This colourless compound is a derivative of benzoic acid.

Usage:

Dicamba controls annual and perennial rose weeds in grain crops and highlands, and Dicamba is used to control brush and bracken in pastures, as well as legumes and cacti. Dicamba kills broadleaf weeds before and after they sprout. In combination with a phenoxyalkanoic acid or another herbicide, dicamba is used in pastures, range land, and noncrop areas (fence rows, roadways and wastage) to control weeds. Dicamba is toxic to conifer species but is generally less toxic to grasses.

Dicamba functions by increasing plant growth rate. At sufficient concentrations, the plant outgrows its nutrient supplies, and dies.

Biodegradation

The soil bacterium Pseudomonas maltophilia (strain DI-6) converts dicamba to 3,6-dichlorosalicylic acid (3,6-DCSA), which is adsorbed to soil much more strongly than is dicamba but lacks herbicidal activity. Little information is available on the toxicity of these breakdown intermediates. The enzymes responsible for this first breakdown step is a three-component system called dicamba O-demethylase. One component of the three has recently been incorporated into the genome of a variety of crop plants making them resistant to dicamba.

Package and Storage:

Keep in shaded, cool 25kg fiber drum and air places. The shelf time is 2 years.
