Synopsis

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.
