Fungitoxic properties of scarlet pimpernel (Anagallis arvensis) against Helminthosporium sativum and Fusarium oxysporum

The antifungal effects of scarlet pimpernel (Anagallis arvensis L.) extract or dried materials on wheat leaf spot (Helminthosporium sativum King & Bakke) and tomato wilt (Fusarium oxysporum Schlecht) fungi were investigated using different experimental techniques under laboratory conditions. Results showed that shoot and root extracts or dried materials of A. arvensis incorporated in the medium severely reduced the growth and development of H. sativum, but showed less effects on F. oxysporum. The fungitoxic activity of weed increased with plant age and shoot extracts were more inhibitory to both fungi species than roots. Results indicated the high potential of using this weed or its extracts to develop a fungitoxic natural chemical/s effective in controlling these problematic plant pathogens.
