In March 1935, at the end of the very extensive campaign of 1934-1935, field experiments were being conducted with the object of studying the technique of the application of bait against the hoppers of the brown locust. During the campaign, serious stock losses had resulted from excessive spraying with sodium arsenite solution, and this led to agitations against its use by the farming community. It was consequently felt that for future campaigns the policy of large scale spraying would have to be abandoned, and that the use of sodium arsenite would have to be limited as far as possible.
