Antifungal activity of some plant extracts and Trichoderma spp. against cucumber damping off caused by Pythium aphanidermatum
Abstract
The present study aimed to use some plant extracts and two different species of Trichoderma spp. to control damping off disease in cucumber caused by Pythium aphanidermatum instead of using chemicals where serious environmental problems caused by several chemical fungicides. Some plant products such as plant metabolites and plant based pesticides considered to be better alternatives as they are known to have environmental impact as opposed to chemical pesticide. In the antagonistic assay that carried out with Trichoderma spp., the results revealed high inhibition on the tested pathogen, but in an assay of plant extracts somerplant extracts with different concentrations were tested in vitro for their activity against P. aphanidermatum. Some of the tested plant extracts significantly reduced the radial growth of the pathogen. Cinnamon, carnation and camphor were the most affective from all the eight tested plant extracts than the other extracts, where with the concentration of 30.000ppm Cinnamon, Carnation and Camphor gave the highest inhibition values against P. aphanidermatum, while mango and mint extracts did not give any inhibition for the radial growth of P. aphanidermatum.
