Biocontrol potential of essential oils against wheat rust diseases and their effects on wheat yield components

Abstract

A field experiment was conducted to evaluate the effectiveness of some essential oils against wheat rust diseases. Three essential oils were tested namely;- Lavandula angustifolia, Melaleuca alternifolia, and Mentha piperita. In the same experiment in other plots, two commercial fungicides (Riza 250EW and Revyona), one plant conditioner (Rhizomagic), and a control were included to compare the results. Analysis of variance showed highly significant differences among the treatments where the standard commercial fungicide reduced the disease severity compared to the control. However, no significant difference existed between the tested essential oils and the control. .
