Colex-D is a novel Choline salt formulation of 2,4-D that allows broadacre growers with proximity to 2,4-D sensitive crops, to access the robust weed control of 2,4-D in fallow with reduced risk of off-target damage. When used in accordance with the label directions, and following industry spraying guidelines, the built in Drift Reduction Technology, Near-zero volatility and Ultra-low odour means Colex-D is a 2,4-D that you can apply with confidence.
Drift Reduction Technology
Patented Drift Reduction Technology, when used with prescribed nozzles and pressures, eliminates Extremely Fine droplets and significantly reduces Very Fine and Fine droplets. This ensures more of the applied product lands on the target and there is less potential for off-target physical drift.
The choline salt formulation, unique to Colex-D, remains more stable in the spray solution resulting in a greater than 86% reduction of volatile loss of the choline salt compared to the amine salt form. This gives greater confidence to farmers that the risk of off-target movement and potential damage through volatility is reduced.
The Corteva Agriscience patented formulation and refined manufacturing process has produced an ultra-low odour formulation making mixing, handling, and application a more pleasant experience for the applicator and the community.
Corteva Agriscience has thoroughly tested the labelled mix partners to ensure physical compatibility and field efficacy in Australian conditions as well as wind tunnel testing to ensure that the Drift Reduction Technology is not impacted.

Corteva Agriscience has applied its commitment to finding better chemistries for the 2,4-D family by creating Colex-D herbicide just as effective on hard-to-control weeds but with the added benefits of near-zero volatility, ultra-low odour and Drift Reduction Technology, meaning it’s better for you, and better for your neighbours.
