Management of the most Destructive Diseases of Chia plant and its Impact on the Yield

Chia (Salvia hispanica L.) is one of the most important medicinal plants recently introduced to Egyptian cultivation and has significant multiusing in human curing. Fusarium oxysporum, F. roseum, semitectum, solani, Macrophomina phaseolina, Pythium ultimum, Rhizoctonia solani Sclerotinia sclerotiorum were isolated from infected plants, showing root stem rot symptoms collected different localities Giza Fayoum governorates. The fungi significantly realized (%) damping- off rot.  Rhizoctonia M. phaseolina oxysporum aggressive pathogenicity test. Bacillus spp. Trichoderma gave degrees antagonistic effects against tested pathogens, i.e., R. vitro. Ascorbic citric acids at 500 ppm recorded 100% seed germination Under greenhouse conditions, Bio-Zeid, T. harzianum, B. subtilis ascorbic acid highest decreasing percentages pre, post- emergence off, maximized healthy survivals. field harzianum decrease plant survivals two experimental seasons, as well increased growth parameters compared with control (without treatment). Thus, it could be suggested that any Bio-Zeid formulated compound, also, can used for controlling chia damping-off
