A study was made with glucose-1-C14, glucose-6-C14, and glucose U-C14 to determine quantitatively the effects of 2,2-dichloropropionic acid (dalapon) on glucose utilization in roots and shoots of one-week-old barley seedlings. An attempt also was made to determine the major pathway of glucose metabolism involved. Dalapon apparently did not change the normal pathway of glucose metabolism but interferred with glucose utilization as evidenced by differences in radioactivity of sugars and organic acids. Partial blocks may be operative initially at the beginning of the glycolytic pathway and subsequently in the Krebs cycle.
