Abstract
Abstract
Abiotic fungal disease agent that reduces the production of Phaseolus vulgaris plants. Rhizoctonia root rot disease results in substantial financial losses for a variety of commodities, including Phaseolus vulgaris. In this study, the defense mechanism of Phaseolus vulgaris against Rhizoctonia solani was improved by the use of isolated soil algae as biofertilizers in comparison to the impacted control. Two algal isolates, Spirulina platensis and Chlorella sp., improved plant germination and physiology in vivo. P. vulgaris was deposited on ground that was coated with algal flour after being immersed in fungal spore solution. The results indicated that the severity of the illness was alleviated and reduced by the addition of Chlorella sp. and S. platensis pre- and post-emergence. Using algal extract as a biofertilizer proved to be the most effective treatment method. The highest levels of chlorophyll a and chlorophyll b were recorded in Phaseolus vulgaris plants treated with Spirulina platensis, reaching maximum values of 1.9 ± 0.07 and 1.75 ± 0.08, respectively.
