Abstract

Relationships between the composition of 2,4-D solutions and their effectiveness as herbicides were investigated. The measure of effectiveness was the reduction in fresh weight of the growth above the primary leaves of bean plants. Two methods of application were used: the drop method (0.01 ml of solution) and the spray method. Variables studied were: diluents, humectants, surfactants, types of amines and esters, concentration, and dosage. Other studies included the effect of point of application on effectiveness and on the distribution of radioactive 2,4-D in the treated leaf and in the plant. For comparative purposes, some similar studies were conducted with radioactive aminotriazole and maleic hydrazide.
