Use of 2,4-D Weed Killers on Woody Weeds in Cuba

Abstract

A rather complete theory of induced lethals in Drosophila which was proposed by Lea and Catcheside (1945) has met with objections. In radiation-induced lethals there is difficulty in the interpretation of the dependence of frequency on dose. There is a nonlinear effect, leading to a very significant discrepancy between this theory and the exptl. data. An estimate of the great importance of this discrepancy is discussed.
