Phytopathological and biochemical impacts of Trichoderma harzianum and certain plant resistance inducers on faba bean root rot disease

Abstract Background Faba bean attacked by soil-borne pathogens causing root rot disease. This disease has serious damage to both plant stand and produced yield. The present study aimed evaluate effectiveness of the bioagents; Trichoderma harzianum some resistance inducers as fungicide alternatives against incidence at pre- post-emergence growth stages. Results Under open greenhouse conditions , faba in phases was considerably reduced using six inorganic salts five antioxidants individually or combining with each other bio-stimulator T. that exceeded used fungicide, Rhizolex-T. Application enervit agitated highest significant defensive impact during pre-emergence stage versus (5.0%), followed calcium sulfate [cysteine + ] (6.7%). At stage, majority treatments completely suppressed (100.0%) incidence, except vitamax plus (Rizolex-T) which expressed 91.7 18.8%, respectively. Duplicate irrigations 23 after dressing improved synthesis different protein contents 2nd enhanced higher than 1st one, [ vitamin E C selenium plus], plus] cysteine. Disodium phosphate induced catalase (CAT) activity (1820.8 1677.2 U/g FWt) irrigations. peroxidase (POD) 217.4 356.9 FWt irrigations, chitinase (CHIA) 52.8 54.4 disodium phosphate, sulfate, potassium metabisulfite, sodium cysteine, potash alum], enervit, E, [vitamin enervit], selenium], E], stimulated formation new bands on SDS-PAGE irrigation treatment. Conclusions Such are considered good environmentally safe diseases for getting rid negative effects fungicides.
