Abstract

During the end of October and the beginning of November, 1955, wheat in a very advanced stage on the farms Merwede and Vlakpan in the Bethlehem district was infested with aphids. It so happened that some of the wheat fields on Merwede were sprayed with 2,4D airspray mixture at the tillering stage and it is only natural that the damage done by the aphids was generally believed to be due to the weedicide.
