Abstract
Grapevine root rot prevalence, incidence and severity were varied with plant age and grape variety. Young vineyards (1-3 years old) provided the highest values of prevalence, incidence and severity at Minia governorate, Egypt. Roomy grapevine variety recorded prevalence; incidence and severity values for root rot higher than Superior grapevine variety. Isolates of Fusarium sp. were the most frequent fungi associated with rotted grape roots followed by Rhizoctonia solani isolates, while other fungi, viz. Alternaria sp. Aspergillus sp. Penicillium sp. Diplodia sp. and Nigrospora sp. were the least frequent. Among 10 fungal isolates tested, Fusarium sp isolate G5 was the most infective followed by R. solani isolate G3 and Fusarium sp isolate G1. Identification of the most pathogenic isolates was confirmed as F. solani isolates G1 and G5 and R. solani isolate G3 that were used further. Varietal response to root rotting fungi was varied with grapevine varieties and fungal isolates. Black desert grapevine variety exhibited resistance against F. solani and R. solani infection. Two grapevine varieties, Flame seedless and Early sweet reacted as moderately infected. The most susceptible variety was Superior followed by Roomy. A beneficial effect for potassium silicate against fungal growth and root rot infection was pronounced at 2mM.
