Interpretive Summary:

Technical Abstract: Eleven isolates of Sclerotinia minor, including one non-sclerotial-forming isolate (9M-N) were used to study the relationship between pathogenicity and oxalic acid production. Oxalate production by all isolates was measured in potato dextrose broth (PDB), in soil, on lettuce leaves, and on peanut stems by quantitative enzymatic analysis (Sigma Diagnostics, St. Louis, MO). All isolates produced oxalate, and all were pathogenic to peanut except for 9M-N. All isolates produced oxalate and were pathogenic on detached Romaine lettuce leaves, except 9M-N which was less virulent. The data suggest that oxalic acid is not the sole pathogenicity factor in S. minor on either peanut or lettuce.
