Toxicity of 2-Chloro-6-(Trichloromethyl) Pyridine in Soybean (Glycine Max L. Merr.) Seedlings1

  1. D. Riley and
  2. S. A. Barber2



Soybeans were grown for 18 days in a silt loam soil containing O to 20 ppm 2-chloro-6-(trichloromethyl) pyridine (N-Serve). Yield of shoots was reduced by concentrations of 8 and 20 ppm and their morphology was altered with concentrations as low as 1 ppm. Yield of roots was not greatly affected by up to 20 ppm, but their morphology was drastically altered with 8 and 20 ppm. Production of NO3 in the soil was reduced 90% by 8 and 20 ppm, 60% by 3 ppm and only slightly by 1 and 0.5 ppm of 2-chloro-6-(trichloromethyl) pyridine.
