Abstract

Five strains of Johnsongrass [Sorghum halepense (L.) Pers.] in selected and random plantings received repeated foliar applications of 2,2-dichloropropionic acid (dalapon). For three characters studied, the residual variance was less with selected plantings than with random plantings. Johnsongrass strains differed in their response to dalapon.
