Evaluation of the Rhodotorula glutinis in Controlling the Gray Rot Disease Caused by the Pathogenic Fungus Botrytis cinerea Pre and Post Strawberry Harvesting

Abstract The effectiveness of the yeast Rhodotorula glutinis was evaluated in field experiment for control gray rot disease on strawberry caused by fungus Botrytis cinerea. results showed that all treatments R. led to a significant superiority inducing systemic resistance and an increase vegetative, productivity quality indicators three cultivars, compared Prado fungicide treatment pathogenic only. Treatment filtrate cells ( - Cs +F with B. cinerea ) achieved highest activity enzymes induce plant resistance, which included peroxidase, chitinase β-glucanase, enzymatic 2.25, 2.31 1.62 units/ml Albion cultivar, other treatments. +F) presence recorded vegetative parameters, height shoot weight reaching 27.33 cm 14.66 g, respectively. All affecting severity infection studied cultivars under conditions , cultivar decrease reached 17.37% ), while it had least effect Festival 95.28% fungus. yield fruits superior as 68.92 g/plant (R. glutinis-Cs lowest 16.69 intensity, hardness vitamin C content after 7 days harvest,
