"Fusariumgraminearum is the fungus that causes fusarium head blight in cereals," says James Calpas, provincial integrated pest management specialist with Alberta Agriculture. Food and Rural Development's Pest Risk Management Unit, Edmonton "The fungus causes direct yield loss in cereals and also produces mycotoxins in the infected gram The most common mycotoxm produced b\; Fusarium graminearum is deoxynivalenol (DON) The presence of DON in grain reduces the marketability of (he grain and has negative effects on the health of ; In areas where Fusarium graminearum is well established, such as Manitoba and south eastern Saskatchewan, the fungus overwinters primarily in cereal straw and stubble This means that straw from these areas is very likely to contain Fusarium graminearum The fact is that Fusarium graminearum infected straw is being brought into Alberta. Tests for Fusarium graminearum carried out on some straw shipments have demonstrated infection levels of 40 to SO per cent Samples from grass hay have also been submitted for testing The test results have not yet been received, but it is likely that there will be some Fusarium graminearum present "Farmers are encouraged not to buy straw or ha\ that has not been tested and found free of Fusarium graminearum, " adds Calpxs. "When the hay and straw is handled, do not spread the material in or near tilled fields Infected straw represents a very high risk for introducing Fusarium graminearum into a field.
