Abstract

The study was conducted to determine fungal communities associated to strawberry plant roots, densities of nematodes in fumigated soil and physico-chemical properties of soil in three commercial strawberry plots (Dlalha, Ouled Aguile and Gnafda) located in Gharb region and visited three times during 2013-2014 season. Under a slight variation of soil temperature and humidity with specific physico-chemical characteristics, a high infestation level of soil by nematodes was marked in the studied farms over the periods of sampling. The lowest number was observed in the first visit attaining 1000 units/g of soil, increased to 5000 units/g of soil in the second sampling period at one site and in the last visit, a significant decrease trend occurs for the big plot which the number of nematodes was reduced to 1500 units/g of soil. The analysis of fungal communities colonizing roots of strawberry plants showed the presence of 13 fungal species. Rhizoctonia solani presented a higher frequencies of isolation from roots of Festival variety reaching respectively 36% and 26.72% in the first and the second visits of Dlalha farms compared to those recorded in the second visit of Ouled Aguile (18%) and Gnafda (13.6%) farms. The Fusarium genus was represented by F. solani, Fusarium sp.1 and Fusarium sp.2 detected at frequencies not exceeding 7.08%. Those of C. gloeosporioides reached 12%, Phytophthora sp. (15.8%). In addition, the appearance of A. alternata, C. herbarum, Aspergillus sp., Circinella sp., Ulocladium sp. and Trichoderma asperellum was more frequent during the three sampling periods.
