Western Canada’s worst crop disease is still a serious issue, researchers say BY ALLAN DAWSON Co-operator staff / Ottawa

his was one of the worst years for fusarium h e a d b l ight in western Canadian spring wheat — a sobering backdrop to the 8th Canadian Workshop on Fusarium Head Blight, held here Nov. 20-22. More than 200 scientists from Canada, the United States, Germany, England, Australia, Switzerland and beyond reviewed the latest research into fusarium head blight, a yield- and qualityrobbing fungal disease. “The 2016 western Canadian wheat harvest is potentially the worst on record for fusarium head blight (FHB) damage and DON (deoxynivalenol, a mycotoxin) levels in many crop districts,” Canadian National Millers Association president Gordon Harrison told the meeting. “Fusarium damage is 1.5 to five times more than experienced in recent years.” The United States suggests

s Alberta begins to feel the repercussions of a confirmed case of bovine tuberculosis (TB), Manitoba looks to close its nearly two-decade-long chapter with live animal TB testing. “As we witness what is happening in Alberta, it really shows how quickly this can take place and how fast it can affect the entire province. We certainly don’t want to go back there,” said Brian Lemon, general manager of the Manitoba Beef Producers. Manitoba has been dealing with TB in the Riding Mountain National Park (RMNP) region since 1991. In 2000, a task force for bovine TB was established to co-ordinate a program to eliminate the disease. This task force includes representatives from Manitoba Conservation, Manitoba Agriculture, Canadian Food Inspection

Agency (CFIA), Parks Canada, Manitoba Beef Producers and the Manitoba Wildlife Federation. “We are well into this year’s activities and two of the most significant things from past years are not on the table this year. No. 1, we are not doing any testing of domestic livestock herds and it is the first time in a long, long time,” said Allan Preston, lead co-ordinator of the RMNP TB eradication project. “And secondly, we are not doing any live capture of elk or deer in the core area of the park. We are relying instead on hunter-kill surveillance, so the absence of those two key activities tells you that we are well along the road to our ultimate goal of eradicating the disease.” During the 2015-16 TB eradication program, 39 domestic livestock herds were tested, resulting in 4,300 negative test results. Approximately four herds were put under quarantine as the wet spring made pen conditions unfavourable for testing. Hunter-killed submissions of 162

white-tailed deer, 74 elk and three moose were all returned negative. Seventy-three mature cow elk were live tested, all returning negative results. Following this clean bill of health, CFIA announced this spring Manitoba would no longer need to undertake live animal testing through the eradication program. “It has been a long, long road for us but it is not the time to take our foot off the gas and assume we are out of the woods either,” Lemon said. When it comes to cattle, Preston says that as long as slaughter samples continue to come back negative, the eradication program will not conduct any live animal testing or any ongoing capturing of live animals in the coming years. “On the wildlife side we still need a certain number of hunter-killed samples to make sure we are covering the bases and if we have less than an optiSee TB on page 6 »
