Kansas regulators on Wednesday lifted an embargo on wheat from 20 fields and three grain elevators in seven south-central Kansas counties after test results showed no detectible traces of a toxic fungicide applied too close to harvest. But a separate later embargo remained in place on wheat from 11 northern Kansas counties, pending test results from those fields, said Lisa Taylor, spokeswoman for the Kansas Department of Agriculture. “This is good news for the affected farmers and for the Kansas wheat industry,” Kansas Secretary of Agriculture Adrian Polansky said in a news release announcing the first results. Regulators had been especially concerned about south-central Kansas, where harvest has begun. On Tuesday afternoon, they embargoed some fields in seven south-central counties even before the test results were back. They were concerned about preventing potentially toxic wheat from those fields from reaching elevators and possibly contaminating the rest of the state’s winter wheat crop. Test results are expected Thursday on samples from 11 northern-Kansas counties where farmers also improperly sprayed with the fungicide Quilt, which requires a 45-day waiting period between application and harvest. Wheat prices surged Wednesday, a day after the news broke that Kansas had embargoed some winter wheat and more rain hit the flood-ravaged Midwest. Wheat for September delivery shot up 32 cents to $9.20 on the Chicago Board of Trade. About 1,545 acres in Butler, Cowley, Harper, Kingman, Reno, Sedgwick and Sumner counties were initially embargoed Tuesday afternoon, along with grain at three elevators in Wellington, Garden Plain and Hutchinson. Test results are now pending on 51 fields encompassing 5,475 acres improperly sprayed in Decatur, Ellis, Gove, Jefferson, Logan, Phillips, Rawlins, Sheridan, Sherman, Thomas and Trego counties. A separate embargo for those fields was issued Tuesday night. Polansky said Wednesday that regulators expected to find similar results from those samples. “Protecting the integrity of the Kansas wheat crop and the reputation of our state as a provider of wheat to the world is of utmost importance,” Dusti Fritz, chief executive officer for the industry group Kansas Wheat, said in a statement. “We feel confident that a limited number of wheat fields in northwest Kansas, also under investigation, will yield the same good results.” Meanwhile, the south-central Kansas farmers whose fields initially caused the wheat scare tried to get on with harvesting unaffected fields as best they could Wednesday. Leon Sowers, a Murdock farmer who had 250 acres embargoed, said he had a custom applicator put on the Quilt fungicide on May 14 to see whether it would help alleviate leaf rust problems. “At the time, none of us were aware there was a 45-day waiting period,” Sowers said. He already had cut some of it and taken it to an elevator before the embargo was imposed. “We have other fields we are cutting,” Sowers said Wednesday before the results were announced. “It just makes us move around more.” Augusta farmer Dean Ogle said his fields were sprayed late because the custom applicator he hired was behind on his workload. He said the embargo of his fields would not have much effect on him because he planned to keep that grain on the farm for seed next season. Jarrod and Sarah Lawrence sprayed about 140 acres at their Oxford farm with the fungicide in early May. She said they were aware of the 45-day waiting period before harvest but that they missed it by just one or two days when they decided to start cutting.“We don’t understand why it is even embargoed,” she said.She said that with all the rain the area has been getting, it would be hard to keep any chemicals on the crops. The couple applied the fungicide to protect their yields.“Basically, applying fungicide is somewhat similar to buying insurance: You are doing everything you can so you can get a paycheck come harvest time,” she said.
