Wheat tracked corn and soyabeans lower as commodities markets, in general, retreated in tandem with lower crude oil prices. Oil prices dropped about 6% on Tuesday after a Monday rally that took prices up more than 12 percent. Wheat was weighed down by headwinds in export markets due to ample wheat supplies in rival exporting countries.
The US Department of Agriculture, in a weekly crop progress report on Monday, said that 8% of the winter wheat crop had been planted as of Sept. 15, in line with market expectations.
