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.

Tips For Use

Restraints: 

  • Do not apply if rain is expected within 4 hours.
  • Do not apply to crops or weeds under stress (not actively growing) due to periods of extreme cold or heat, moisture stress (waterlogged or drought-affected), poor nutrition or previous herbicide treatments as increased levels of crop effect and/or reduced levels of weed control may result.
  • Do not mix with hard water (>500 ppm) or water containing suspended matter.

Protection Of Crops, Native And Other Non-Target Plants:

  • Drift warning:
    • Do not apply under meteorological conditions or from spraying equipment that could be expected to cause spray drift onto nearby susceptible plants, adjacent crops, croplands or pastures. 
    • Avoid spray drift and vapour movement onto susceptible crops such as cotton, tobacco, tomatoes, vines, lupins, fruit trees and ornamentals.

Protection Of Livestock:

  • Spray-Grazing Warning:
    • Some pasture weeds can be controlled by Spray-Grazing a combination of herbicide treatment followed by heavy grazing 7-10 days later. 
    • Sprayed weeds become more palatable to stock and a higher intake of some weed species after spraying can cause stock deaths and other problems. 
    • Increased quantities of poisonous plants may be eaten by stock when the Spray-Grazing technique is being used. 
    • Take care if pastures are dominated by Caltrop, Capeweed, Cape Tulip, Paterson’s curse (Salvation Jane) or Variegated Thistle. 
    • With Paterson’s Cures preferably graze stock soon destined for slaughter and avoid extended periods of grazing. 
    • Avoid grazing with young or breeding stock. 
    • Do not graze horses or pigs in Paterson’s curse (Salvation Jane) infested pasture.

  • Do not contaminate streams, rivers or waterways with this product or used containers.
