Abstract: Alternaria leaf blight is a significant problem on mustard and the only way to control it is to use chemical pesticides. Due to environmental concerns and the likelihood of fungicide residues, this is not a brief solution. Because it increases the activity of various defense-related enzymes and non-enzymatic antioxidants, induced resistance is one of the most popular options. The effect of elicitors pre-sowing seed treatment on seed vigour and thus on induction of resistance to manage the disease was investigated in a net house with three different mustard types. On uninoculated plants, elicitor treatments had a higher vigour index of mustard seeds than the water sprayed control. These changes are linked to the role of elicitors, and it is well known that pre-sowing elicitor therapy, which is a viable and cost-effective strategy, improves plant defense systems and seedling character.
