Synopsis Greenhouse tests indicated no reduction in the survival of Rhizobium meliloti on alfalfa seeds and in soil fertilized with ammonium sulfate treated with 2‐chloro‐6‐(trichloromethyl) pyridine. Reduction in seedling growth of alfalfa plants was severe at 20 ppm of 2‐chloro‐6‐(trichlorornethyl) pyridine and slight at 1 ppm. Other deleterious effects on alfalfa seedlings were changes in nodule morphology and deformation of root tips.
