The Australian cotton industry is heavily dependent on the use of chemical insecticides and herbicides. The off-farm movement of these pesticides has created a number of &quote;environmental&quote; issues for the industry. The major ones are related to: the presence of pesticides in the riverine environment; the contamination of pasture and fodder crops leading to residues in livestock, particularly related to the use of Helix' (chlorfluazuron) and endosulfan; community health concerns related to droplet drift and odour.
