Toxicity of 2,4-D in California soils

A. S. Crafts

Hilgardia, 1949, vol. 19, issue 5

Abstract: Tests on several agriculturally important soils show that under California conditions 2,4-D retained in the soil after spraying may injure subsequent crops unless special measures are taken to supplement natural leaching and decomposition. Once decomposition occurs, crop growth is noticeably stimulated. Spraying gives more satisfactory selective control of weeds than direct application of 2,4-D to the soil. Current studies show the chemical to be practical for brush control and range improvement. Its use as a permanent soil sterilant is not recommended.
