However that was solely step one. Nations subsequent wanted to behave on the info in a scientific option to quash locusts. Within the first few months, nonetheless, officers had been strategizing “on the again of envelopes,” Mr. Cressman mentioned, and all the area had simply 4 planes for spraying pesticides.
