Abstract
Abstract Studies were conducted to determine if 2‐chloro‐4,6‐bls‐(ethylamlno‐s‐triazine (simazine) or 3‐(3,4‐dichlorophenyl)‐l,l‐dimethylurea (diuron) increased the nitrate or Kjeldahl N content in the shoots or roots of wheat ( Triticum aestivum L.) or soghum ( Sorghum blcolor (L.) Moench)plants. Wheat and sorghum plants were grown in nutrient solutions containing several concentrations of these two herbicides for various time intervals. Nitrate N and Kjeldahl N were determined in shoots and roots and expressed as totals per plant. Simazine‐ and diuron‐treated wheat plants had a higher nitrate N content and lower dry weight than control 6 days after treatment. The Kjeldahl N per six plants was reduced by diuron and was not affected by simazine. Diuron at 0.25 ppm was phytotoxic to wheat. An increase in nitrate was usually accompanied by a decrease in dry weight.
