Biological control of Botrytis allii by Trichoderma viride on onion Allium cepa

Type: article
Abstract: Several pathogens attack Egyptian onion crop causes many looses in yield, one of those important causal pathogens is Botrytis allii the causal pathogen of umbel Head blight disease. B.allii was isolated from infected onion plants grown in an open field in Assiut Governorate, Egypt. All the tested isolates infected onion plants with different degrees of disease severity. The antagonistic efficiency of Trichoderma spp evaluated in in vitro study. All Trichoderma spp. suppressed the growth of B..allii with different degree. Results of antagonistic capability showed that Trichoderma viride caused the highest reduction of the growth compared to other species, 86%, 84% and 85% for T. viride and T. harzianum respectively. Under greenhouse conditions the confrontation of T. viride affected on the causal pathogen growth with different rates decreased the disease severity around 45% in 2010 season and around 30% during 2011 season. Results can be suggested that use of T. viride as biocontrol agents under greenhouse condition but these results need to confirm by field study.
