Detection of Presumptive Mycoparasites in Soil Placed on Host-Colonized Agar Plates in Riyadh Region, Saudi Arabia

Y.Y. Molan

Abstract: The presumptive mycoparasites Trichoderma sp., Pythium sp., Gliocladium sp. and Verticillium sp. were detected in 42 (51.2%), 2 (2.5%), 23 (28.4%) and 1 (1.2%) of a total 81 soils, respectively, when soil samples were placed on sectors of potato dextrose agar colonized by the appropriate host fungi. Most (81) of the soils in the study contained three or more mycoparasities, but the frequency of detection on replicate host sectors suggested that Trichoderma sp. and Gliocladium sp. were the more abundant species in all soils in which they occurred. The type of host fungus markedly influenced the efficiency of detection of the different mycoparasities: Fusarium sp. was most efficient for Trichoderma sp. and Gliocladium sp. and Rhizoctonia solani for Trichoderma sp. Only a single host was suitable for consistent detection of each of the mycoparasite species.
