EACH year some 450,000 acres of cereal crops in Western Australia are sprayed for the control of weeds. Of this area more than two-thirds is treated from the air. During the present season 32 aircraft will be engaged in the weed spraying programme. This means that the aerial spraying capacity this year will be approximately double last season's operations.
