| A survey of pink root rot, Stemphylium blight and powdery mildew as new recording fungal diseases on garlic were conducted in 60 garlic fields at different localities of four governorates at East Delta region of Egypt, during 2013/2014 and 2014/ 2015 growing seasons. Pink root rot disease caused by P. terrestris was found on garlic Seds-40 cv., more than on Balady one. The disease was appeared 120- 130 days after planting in naturally infested soil. The occurrence of garlic pink root rot disease was widely prevalent in Ismailia Governorate, followed by Suez and North Sinai Governorates, meanwhile Skarkia Governorate showed the least percentage of infection. Stemphylium blight caused by S. vesicarium was appeared 50- 60 days after planting in naturally infected fields. The disease was widely prevalent in Ismailia Governorate followed by Sharkia and Suez Governorates while North Sinai showed the least infection. Powdery mildew disease was appeared 90- 100 days after planting in naturally infected fields. The occurrence of garlic powdery mildew caused by L. taurica was widely prevalent in North Sinai Governorate, followed by Ismailia and Suez Governorates, while Sharkia Governorate showed the least infection. Pathogenicity tests revealed that isolates caused pink root severity ranged between 23.31-70.20%, Stemphylium blight infection ranged between 53.76 - 68.22% and powdery mildew severity ranged between 47.70-59.80% on garlic Seds-40cv. | ||||
