Wafaa M. Haggag Research Professor in Plant Pathology Department, Dokki, Cairo, Egypt was graduated from Faculty of Agriculture, Cairo University in 1986 and she got her M.Sc. and Ph.D. in Plant Pathology in 1993 and 1998, respectively from Ain Shams University. She has a 26-year experience on scientific and demonstration projects, authored many papers and awarded by several Organisations.Dr. Wafaa joined several scientific societies, participated in several projects and published more than scientific articles in different international scientific journals. She also organized and participated in many international congresses and many local scientific symposiums.Over and above, Dr. Wafaa has an effective social activity, since she participated in many social seminars held in the agricultural communities to learn women working in agriculture how to produce safe food and to keep environment contamination free.
Wheat and Barley are important staple cereals in Egypt. Climate change is also expected to reduce the suitability of wheat and barley production in low-latitude regions, including most of the developing world. New sustainable technologies are required to develop such resources into economic value to be added. Nowadays, the most prevalent tools to control plants are the use of intensive agrochemicals irrespective of their high cost and deleterious impacts on health and environments.
Resistance against plant pathogens and stress is one of the key factors in production systems. Recently, there has been considerable interest in developing biological strategies using benefit microorganisms with antimicrobial activities for controlling pathogens and pests.
The aim of this study is to investigate the effective use of different bio-elicitors to improve plant tolerance of wheat and barley crops against biotic stress as pests and as abiotic stress. Bio elicitors reduced abiotic stress and increased total phenols, peroxidase, chitinase and total soluble protein in both varieties, promote growth rate, reproductive yield, flour starch , protein contains and glutamine in grain seeds and regions.
Experiments revealed a remarkable increase of growth, and extended survival under salt and water limiting conditions. These findings indicate that wheat plants can exhibit enhanced stress tolerance via bio-elicitors , and suggest that technology may be useful in alleviating impacts of climate change on other crops and expanding agricultural production onto marginal lands. Application of this bioelicitor will be lead to an induced defence response thereby decreasing the amount of pesticides used in agricultural pest management. In turn that would benefit the environment, as well as the health and safety of food producers and consumers.
