Isolated acyl solamines significantly inhibit mycelial growth of both pathogens at low concentrations.
Half-maximal inhibitory concentrations are 150 mg/L for alternaria solani and 94 mg/L for botrytis cinerea.
The dominant compound in the acyl solamine fraction was C16:3-solamine with over 90% purity.
Research indicates potential applications in potato production and integrated pest management strategies.
