Abstract


The reduction in the growth of pathogen under abiotic stress is being intensified by DL-β-amino butyric acid (BABA). The combination of abiotic and biotic stress can have a positive effect on the yield of plants by reducing the sensitivity to biotic tension and limiting the crop yield and more priority has been given on the surface of the research table now a days. Therefore this study was carried out observe the effect in combination of Fly ash and BABA in resistance to Root knot nematodes. In our recent study, BABA has been tested to manage Meloidogyne incognita under stress conditions due to fly ash. Results indicate that 30% fly ash in combination with BABA (125 μg/ml) undoubtedly reduced the gall Index by 50% when compared with the control. The interesting thing is that the lower dose of BABA when combined with the abiotic stress was similar to the high dose of BABA efficacy (250 μg / ml).
