Evaluation of compost and compost extract efficiency as bio-control agents on damping-off disease incidence of fenugreek (Trigonella foenum-greacum [electronic resource].

Includes references.

Compost and compost extract efficacy as bio-control agents for damping-off disease of fenugreek plants (Trigonella foenum-greacum) was evaluated. The disease causative fungus, Fusarium solani (Mart.) Sacc, was isolated from El Sharkia Governorate. A pots experiment was carried out for fenugreek cultivation using different combinations of compost, compost extract, and F. solani. Incidence of damping-off, plant growth parameters, and populations of bacteria, fungi, and actinomycetes were deterntined. The results showed that fenugreek plants were highly affected by preemergence damping-off incidence (23.33%), and to a lesser extent by post-emergence damping-off (16.66%). Applying the recommended dose of compost (RDC) and irrigation with compost extract (CE) almost prevented the pre- and post-emergence damping-off (3.33% for both). Such result was concomitant with a decrease in the total number of fungi in most treatments, and a significant increase (P<-0.05) in the total number of bacteria and actinomycetes after 30 and 45 days of cultivation.
