Green matrix solution for growth inhibition of Venturia inaequalis and Podosphaera leucotricha
The goal of the study is to evaluate the ability of hydroalcoholic and ethanolic extracts of mature leaves of Dryopteris to inhibit the growth of Venturia inaequalis and Podosphaera leucotricha. Dryopteris commonly called wood fern or buckler fern, is a genus of about 300 species of ferns with distribution in Europe, Africa, eastern Asia, the Americas, and the Pacific islands, with the highest species diversity in eastern Asia. The crude hydroalcoholic and ethanolic extracts were characterized by analytical techniques and in terms of phytochemical assays. HPLC analyses revealed the presence of several compounds (such as chalcone with concentration varying from 3 to over 93 mg L‑1, rutin between 9.26 to over 39 mg L‑1 and chlorogenic acid, present only in some extracts, at concentrations between 3.68 and 22.97 mg L‑1). The crude extracts were found to be active against both fungal lines used in this study (responsible for the occurrence of the most common apple diseases).
