1958: Burdekin Region (Qld) Spray Drift

Prior to 1958 only two cases of crop damage, both in cotton, were reported in the Burdekin area following herbicide application by aircraft.
In 1958 and 1959, incidents involving damage through application of herbicides by aircraft in Queensland led to the appointment of a select committee to study the problem.
