In France, the recommendation for the first nitrogen application on wheat is 6 weeks before Z30, with the second application on Z30. Wheat growth regulators are typically applied at Z30. Disease control is most critical in the stem extension and heading stage (Z31, Z32, Z35), in particular as soon as the flag leaf is out (Z37).
Ug99 is a lineage of wheat stem rust (Puccinia graminis f. sp. tritici), which is present in wheat fields in several countries in Africa and the Middle East and is predicted to spread rapidly through these regions and possibly further afield, potentially causing a wheat production disaster that would affect food security worldwide.

The following international wheat production statistics come from the Food and Agriculture Organization figures from FAOSTAT database, older from International Grains Council figures from the report "Grain Market Report". The quantities of wheat in the following table are in million metric tonnes. All countries with a typical production ...
Global wheat stocks decreased exponentially; Australia was hit the hardest with a 93 percent decrease by 1974 from 1971. [23] Not all nations were equally hit; some, such as Canada, benefited from the deal. Canadian farmers had sold their wheat to the Canadian Wheat Board, which were able to pool stocks and sell as a collective. [24]
Three cereals, maize, wheat, and rice, together accounted for 89% of all cereal production worldwide in 2012, and 43% of the global supply of food energy in 2009, [90] while the production of oats and rye has drastically fallen from their 1960s levels.
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 ...
Cereal production in 2006 stood at 15.1 million tons, including 5.3 million tons of wheat and 8.6 million tons of maize. [7] In 2007, a severe drought destroyed over 60% of crops. Wheat production subsequently fell to 3 million tons, and prices fell 25%. Analysts claimed it was the worst harvest since 1940. [8]
Crops produced in Mongolia include wheat, barley, and potatoes. Animals raised commercially in Mongolia include sheep, goats, cattle, horses, camels, and pigs. They are raised primarily for their meat, although goats are valued for their hair which can be used to produce cashmere. Livestock breeds are increasingly challenged by land degradation ...
