The ELISA (enzyme-linked immunosorbent assay) test for Rhizoctonia solani is a highly sensitive and specific qualitative serological assay designed to detect the presence of this soilborne fungal pathogen in plant tissues and soil samples. This test works by using antibodies that bind specifically to antigens associated with Rhizoctonia solani, allowing for rapid and reliable identification of the pathogen even at low levels. It is particularly valuable for early detection and management of the disease, which affects a wide range of hosts including row crops, ornamentals, vegetables, turfgrass, and woody plants. The ELISA test provides a valuable tool for farmers, agronomists, and plant health professionals to monitor and diagnose infections efficiently, helping to implement timely control measures and reduce crop losses.
