Nineteen essential oils were screened for their toxicity against Aspergillus flavus, Aspergillus niger, and Fusarium oxysporum. The oil of Nardostachys jatamansi DC completely inhibited mycelial growth of all the test fungi at a concentration of 1.0 × 103 ?L/L. The toxicity was fungistatic. The fungitoxic effect of the oil remained unaffected by heavy inoculum, temperature treatment, and storage. In addition to the test fungus, the oil at concentrations of 1.0 × 103 ?L/L and 1.2 × 103 ?L/L inhibited the growth of six and nine other fungi, respectively, and did not adversely affect seed germination and seedling growth of Cicer arietinum and Cajanus cajan.
