Wheat grains infection and control means with plant extracts [electronic resource].

Includes reference.

Wheat (Triticum aestivum) is being attacked by several fungal pathogens, many of them are seed-borne, infesting wheat seeds (grains) are detected by methods as recommended by the ISTA, 1966. Fungi such as Altenaria alternate, Aspergillus flavus, Aspergillus niger, Chaetomium spp, Cladosporium spp, Epicoccum spp, Fusarium spp, Fusarium oxysporum, Fusarium solani, Nigrospora oryzae, Penicillium spp, Rhizoctonia solani, Stemphyllium spp. and Trichoderma spp. were isolated from the wheat cultivars i,e Gemmiza 7, Gemmiza 10, Sids 1, Sids 12, Sakha 93, Sakha 94 and Bani sweif 1. Extracts of pomegranate, Neem and Garlic were screened for the potential antimicrobial activity through cup-plate method against three fungi (F. oxysporum, R. solani and A altemata. All extracts showed inhibitory activites. F. oxysporum, R. solani and A alternata were the greater portions of the isolated fungi. In vitro studies, seed treatment with 10, 20 and 30% of concentration of plant extracts for 24 hours showed a complete germination and all seed testing. In vitro studies using cup-plate method were exercised to examine the antifungal activity of three plant extracts i.e., Neem, Pomegranate and Garlic against such fungi associated with wheat seed. F. oxysporum, R. solani and A alternata were the greater portion of the isolated fungi. Keywords: Triticum aestivum, seed-borne fungi, pomegranate, Neem, Garlic, F. oxysporum, R. solani, A alternata, aquous extracts. seed testing.
