Soil-borne wheat mosaic virus is a rod-shaped plant pathogen that can cause severe stunting and mosaic in susceptible wheat, barley and rye cultivars. [1] The disease has often been misdiagnosed as a nutritional problem, but this has actually allowed in part for the fortuitous visual selection by breeding programs of resistant genotypes.
Bacterial leaf streak (BLS), also known as black chaff, is a common bacterial disease of wheat. The disease is caused by the bacterial species Xanthomonas translucens pv. undulosa. The pathogen is found globally, but is a primary problem in the US in the lower mid-south and can reduce yields by up to 40 percent. [6]

When it feeds on wheat, A. tosichella transmits the wheat streak mosaic virus. Infected plants show long yellow streaks, associated with some degree of chlorosis which may lead to death of the affected foliage. In Oklahoma, the disease usually appears in late April and early May when the weather warms up. [12]

Zymoseptoria tritici infects wheat crops throughout the world and is also currently a big problem in Iran, Tunisia, and Morocco. [17] Severe epidemics of the disease have decreased wheat yields by 35-50%. [17] In the United States, Septoria leaf blotch is a very important disease in wheat, second only to wheat rust. An estimated $275 million is ...
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
The fungal ancestors of stem rust have infected grasses for millions of years and wheat crops for as long as they have been grown. [7] According to Jim Peterson, professor of wheat breeding and genetics at Oregon State University, "Stem rust destroyed more than 20% of U.S. wheat crops several times between 1917 and 1935, and losses reached 9% twice in the 1950s," with the last U.S. outbreak in ...
