RESULTS
the result indicated that the sole and alternate application of AR1 with fungicide reduced disease severity to less than 10%. Plant physiological traits have also been improved due to the plant growth promoting AR1. Induced plant defense-related biochemicals viz., total phenolic and flavonoid contents were maximum in the plant subjected to AR1 and alternate application with a fungicide. In addition, the concentration of leaf amino acid proline has been doubled due to AR1 compared to the control. The concentration of plant growth-regulating hormones: Gibberellic acid and IAA, as well as leaf chlorophyll, total nitrogen and phosphorus contents were also significantly increased by 203.86, 7.79, 0.31 mg gFW-1 , 0.15 and 0.13%, respectively, due to the treatments. Furthermore, postharvest soil chitinase, cellulase and 1.3, β-glucanase activity results indicated the biological control and rapid soil colonization trends of AR1.
