Abstract

Abstract We applied 4‐amino‐3,5,6‐trichloropicolinic acid (picloram) to eight species of herbaceous plants 14 days after planting. Analysis of aerial portions 21 days after planting revealed a significant stimulation in fresh weight of corn, sorghum, cotton, cowpea, and soybean treated at from 0.25 to 0.50 ppb, and wheat at 100 ppb. Significant stimulation in dry weight was noted in corn, sorghum, cotton, and soybean at 0.25 ppb, and cowpea at 1.0 ppb. Significant decreases in fresh and dry weight occurred in corn, wheat, and sorghum at 1000 ppb, and all dicot species at 100 ppb. Herbicide treatments had no effect on the dry weights of rice and wheat, or fresh weight of rice. Herbicide treatments caused reduction in soluble protein concentrations in all monocot species and sunflower. Significant increases in soluble protein occurred at 1.0 and 0.25 ppb in cotton and cowpea, respectively.
