Toxicity of 2‐chloro‐6‐(trichloromethyl) pyridine (N‐Serve) occurred on young plants of bean, corn, cucumber, pea, and pumpkin when its concentration was at least 50 ppm in the soil. A restriction in fresh or dry weight production was the most uniform characteristic of N‐Serve toxicity. Cucumbers and peas showed visible foliar signs of injury which persisted until harvest while beans showed a temporary manifestation of N‐Serve toxicity on the primary leaves. Tomato plants did not appear to be injured at concentrations as high as 100 ppm in the soil.
