Peter Newman, Australian Herbicide Resistance Initiative, Australia
What does it take to achieve ryegrass populations close to zero in cereal crops? Peter presents the results of 13 years’ work in 30 focus paddocks, some using herbicide-only and others with herbicides plus harvest weed seed control. There’s no clearer way to show the value of harvest weed seed control than tracking ryegrass populations against resistance management tactics year-to-year.
