Induction of systemic acquired resistance in tomato inoculated with early leaf blight pathogen

Abstract

The results of this study provide evidence that application of simple non-toxic chemical solutions such as potassium phosphate can control early blight of tomato, Their low toxicity to animals, comparative environmental safety and nutrient value make them ideal foliar fertilizers which can be used for application in the field for disease control. The ability of potassium phosphate to induce high levels of three defence enzymes and four antioxidants in tomato leaf could be of use in elicitation of SAR in disease management programme. Thus potassium sulphate spray to tomato plants can provide a degree of protection to tomato plants against early leaf blight and help in disease control.
