Short Communications


The relative toxicity of nitrapyrin 2-chloro-6-(trichloromethyl) pyridine and ATC (4-amino-1, 2, 4-triazole) on the growth of chick peas (Cicer arietinum L.) cow peas (Vigna sinensis L.), green beans (Phaseolus vulgaris L.), green peas (Pisum sativum L.) and mung beans (Phaseolus aureus Roxb.) and their effectiveness as nitrification inhibitor were studied under greenhouse conditions. ATC produced no toxicity symptoms in green peas, whereas resulted in leaf chlorosis in cow peas, chick peas and green beans. However, nitrapyrin toxicity appeared as leaf chlorosis in cow peas, and interveinal chlorosis in chick peas. Moreover, nitrapyrin-treated green beans and peas developed leaf curling and cupping. Although ATC had no significant effect on growth, a suppression in plant growth was associated with nitrapyrin application. Furthermore, green beans was the most resistant and chick peas the most sensitive to nitrapyrin. Nitrapyrin was more effective nitrification inhibitor than ACT, especially at the lower rates.
