Comparison of measured fenitrothion deposits from ULV aerial locust control applications with those predicted by the FSCBG aerial spray model

Abstract

The deposit of fenitrothion on vegetation arising from aerial control of the Australian plague locust, Chortoicetes terminifera (Walker), was compared with deposition predicted by the FSCBG aerial spray model. The correlation between predicted and actual data suggests that the FSCBG spray model can be used to indicate the impact of varying application parameters, for example, track spacing and flying height, on locust control as practised by the Australian Plague Locust Commission. Any operational changes suggested by the model can then be validated in field trials.
