Effects of varying phosphorus levels on the incidence of fungal pathogens in common bean crops
Author(s): Dr. Sarah N Ndaba
Abstract: Phosphorus (P) is a critical macronutrient for plant growth and disease resistance. This study investigates the impact of varying phosphorus levels on the incidence of fungal pathogens in common bean (
Phaseolus vulgaris) crops in Sri Lanka. Field trials were conducted at the Field Crops Research and Development Institute (FCRDI), Mahailluppallama, during the Yala season. Phosphorus was applied at varying concentrations (0, 20, 40, 60, and 80 kg/ha). Disease incidence caused by major fungal pathogens, including
Rhizoctonia solani,
Fusarium oxysporum, and
Colletotrichum lindemuthianum, was recorded at different growth stages. Results, represented in tables, show that optimal phosphorus levels (40–60 kg/ha) significantly reduced fungal infections and enhanced crop yield. The findings highlight the importance of phosphorus management in reducing fungal pathogen incidence in common beans.
