Agrochemical based disease management is followed majorly by the farmers may lead eventually to resistance breakdown and environmental hazards. For sustainable crop production and maintaining safe agro ecosystem herbal kunapajal is an eco- friendly and promising plant bio stimulant. The present investigation was carried out to test the antifungal properties of herbal kunapajal formulations against Alternaria solani, Colletotrichum capsici, Macrophomina phaseolina, Helminthosporium oryzae and Fusarium oxysporum. All the selected herbal kunapajal formulations showed effectiveness against plant pathogens.Complete inhibition of all the test pathogens was observed at 5% concentration of herbal kunapajal formulations. Enhanced seedling vigour was observed when seeds were treated with different bioformulations. An increase in the plant growth parameters viz., germination, seedling length, vigour, root length, shoot length, root weight, shoot weight, root/shoot ratio, number of leaves per plant and reduction in seedling infection was observed when seeds were treated with 10% concentration of herbal kunapajal formulations in tomato and chilli plants The treated tomato and chilli plants showed elevation in the enzymatic activity of PO, PPO, PAL, SOD, TPC, Hydrogen peroxide (H2O2) and lignin production leading induced defense response in host. Highest increase in enzymatic activity was observed in herbal kunapajal eucalyptus treated plants. It is evident from the present study that the use of herbal kunapjal as a potential bio-formulation can be a sustainable alternative for effective management of phytopathogens.Phytopathogens are amongst one of the major cause contributing significantly towards losses in crop yields and quality.
