Historically research has shown cotton to be highly susceptible to the phenoxy herbicides. However, there is limited information on the impacts of other herbicides that may be used within current fanning systems. Every season there are reported cases of suspected herbicide damage over the summer period. Damage is primarily caused by physical drift of herbicides used for roadside weed control, or summer fallow weed management. The drift associated with fallow management can be from within or outside the farm boundary. Irrespective of where the damage originates, there are always two questions that the grower asks. &quote;What has caused this damage&quote; and &quote;will the crop recover&quote;? It was this scenario that promoted the establishment of this research. This paper examines the impacts of herbicides commonly used for fallow weed control on cotton growth and yield.
