18/08/2014: US farmers fight poisonous wheat fungus with cleaning

Dave Wiechert of Nashville, Illinois, does good business most years cleaning seed for farmers in preparation for planting season. But this year, Wiechert is doing big business after harvest: cleaning fungus off wheat so farmers can sell it, reports Reuters.

 The "head scab" fungus can produce vomitoxin, a chemical that is poisonous to humans and livestock when consumed at high levels. This year, soft red winter wheat has been hit badly by the fungus, which develops when it rains during the crop's key growing period.

Head scab, which scientists call fusarium head blight, can hit profits of farmers and grain handlers hard, while raising costs for bread and cereal makers.

Previous outbreaks cost the US wheat and barley industry US$2.7 billion from 1998 to 2000, then another estimated US$4.4 billion in 2011. It is too soon to know the full economic losses for 2014.


In addition, unsellable wheat has been competing for storage space with bumper corn and soybean crops about to arrive in the autumn harvest. Cleaning the wheat reduces vomitoxin levels as it sifts out damaged grain, but it can cost about US$1 per bushel for farmers. Wheat currently sells at around $5 per bushel.

"This is the worse I've ever seen it," said Wiechert, owner of Wiechert Seed Inc, which he has operated since 1985. The business is 50 miles southeast of St Louis, Missouri, near the epicenter of a vomitoxin outbreak.

"We're trying to get the vomitoxin down to a sellable level and trying to get the test weights up," he said.

Head scab shrivels the grain. This reduces test, or average, weights from the harvest, which also cuts profits. This outbreak will hit farm incomes that are already down for the first time in several years, shrinking 27 percent in 2013/14 from a year earlier, according to data from the US Department of Agriculture.
