The herbicidal effects of 2,4–dichlorophenoxyacetic acid (2,4–D) have been shown to be influenced by a number of factors. Among these are: (a) intensity of light before and after treatment, (b) stage of development and growth of the plant or tissues at time of treatment, (c) reserve carbohydrate supply, (d) temperature, (e) available soil moisture, (f) pH of the solution, (g) surface active agents, and (h) formulation.
