Through the application of novel chemicals or biological agents to the seed in coatings that go on to combat infections throughout the life-span of each plant by reducing the effectiveness of pathogen stealth or attack genes. Last Update July 2. On the one hand we investigate how fungi attack wheat and cause disease by discovering the genes, proteins and chemical metabolites involved, as well as defining the underlying interconnecting networks which co-ordinate the early infection process. diseases and to use appropriate measures to ensure safe practice. https://www.nature.com/articles/s41588-018-0051-x?

If barley stripe rust, which is currently an exotic disease, is introduced to Australia it will cause severe losses in many varieties. Therefore, no-tilling wheat into wheat stubble often results in high disease severity. In most cases, leaf rust requires green volunteer barley plants to survive over summer, and infect new crops the following autumn. Wheat, is the name given to several plants in the genus Triticum including Triticum aestivum, Triticum compactum, Triticum spelta and Triticum durum, which are annual or biennial grasses grown primarily for their grain.Wheat species possess an erect smooth stem with linear leaves that grow in two rows on either side of the stem with larger 'flag' leaves at the top of the stem.
