Qualification of water and alcohol extract of garlic (Allium sativum) to control the growth of some fungi associated with wheat grains

Abstract

This study was involved an investigation about the biological and chemical activity of water and alcohol extract of garlic bulbs plant (Allium sativum) on germination of stored wheat seeds on filter papers and solid media (PDA). Also the effect of those extracts on the growth of fungi isolated from stored seeds on solid media (PDA( These fungi were Rhizopus stolinifer , Aspergillus candidus , A.ochraceus , A.niger , A.fumigatus , A.flavus and Trichocladiumopacum . The bulbs of Allium sativum were selected according to the review of literature and the local uses . In this study wheat seeds were treated with five concentrations of extracts (0.0 ,. 25 , 50 , 75 ,100 )% and 500 mg/l from Benomyl and Mancozeb . The treatments of water and alcohol extracts raised germination rates of wheat seeds to high levels and highly inhibited to all the fungi tested with 100 mg / ml of water and alcohol extracts compared with Benomyl and Mancozeb .The results were showing that the water and alcohol extracts increasing the levels of protein in wheat seeds compared with Benomyl and Mancozeb
