Brian Jenks, weed scientist at the North Central Research Extension Center in Minot will discuss herbicide resistance issues in common grass weeds and kochia.
“We’re seeing an increase in the occurrence of green foxtail and wild oat populations that are resistant to Group 1 and 2 herbicides,” says Jenks. “Unfortunately, we’re also finding some populations with resistance to both modes of action. We’ll also talk about kochia and what we are now seeing in regards to Group 14 (PPO inhibitor) resistance. We’ve been dealing with resistance to Groups 2, 4, and 9 in kochia for some time, but the developing resistance to Group 14 is going to change how we handle this weed.”
The final speaker on the agenda is Frayne Olson, Extension crops marketing specialist who will provide insight into current global and domestic factors influencing grain prices.
“We have a lot of big-picture things happening right now,” says Olson. “It’s always important for growers to understand what is driving the markets and things to consider as they put together their marketing plan for the up-coming year.”
Certified Crop Advisor Continuing Education Units (CEU’s) will be offered in the following categories: 0.5 nutrient management, 2.0 pest management, 1.0 crop management and 1.0 professional development.
