Abstract
  • The potential of the fungus Ascochyta sonchi as a mycoherbicide for the biocontrol of the perennial weeds Sonchus arvensis and Cirsium arvense that occur throughout temperate regions of the world is under evaluation. Ascosonchine, a newly discovered enol tautomer of 4-pyridylpyruvic acid with potential herbicidal properties, is the main phytotoxin produced by this fungus. A simple and sensitive method has been developed for the rapid quantitative analysis of ascosonchine based on HPLC with UV detection. The toxin content in culture filtrates of different strains of A. sonchi was measured. The strains tested produced up to 2.7 mg/L when grown in static conditions. Toxin production was compared with the virulence on the host plant of each strain to determine if the most virulent strains could be simply selected by choosing the best toxin producers. The results obtained do not support this approach. The same HPLC method was also applied to quantify toxin production under different fungal growth conditions, in order to achieve the highest toxin production. The most productive strain synthesised more than 8mg/L when grown for 8 weeks in static conditions. (literal)
