What is the Iowa Pest Resistance Management Program?

The Iowa Pest Resistance Management Program is a grassroots, collaborative effort to protect Iowa crops from costly pest resistance that threatens our crop production and our state’s economy. The program is made up of individuals and groups representing all parts of the Iowa community, including farmers and landowners, small and national businesses, scientists, researchers and state regulators. Together, these groups and individuals have leveraged their resources, expertise and time to help inform the public about pest resistance, find new pest management strategies and encourage public support and adoption of these practices.

How can you get involved?

The Iowa Pest Resistance Management Program (IPRMP) was designed for you to get involved. The program features four pilot programs across the state that are working to combat various types of pest resistance. These include: Managing Western Corn Rootworm in Northeast Iowa; the Harrison County Pest Resistance Management Project in Southwest Iowa; Managing Soybean Aphid in Northwest Iowa; and Managing Herbicide-Resistant Waterhemp in Story County. To learn more about the IPRMP and the pilot programs, check out the Q&A here. To learn how you can lend your support or develop your own community project, please email isuipm@iastate.edu.

Coffee Rust: The Parasite that Wants to Ruin Your Morning

Show: 
I See Dead Plants
Season: 
1
Episode: 
6
Description: 

On this episode of the I See Dead Plants Podcast, host Ed Zaworski takes a dive into the world of coffee and coffee rust. What if the world’s supply of coffee was threatened by a rapidly spreading plant disease that caused coffee tree leaves to fall off the plant and stopped beans from developing? What if our supply of coffee dwindled due to this disease? Will mornings at the office become unbearable as zombie-like coworkers stumble to their desks with sleep still heavy in their eyes? Will the water cooler become a veritable no-man’s land where tempers flare at the slightest provocation? If not for the work that plant pathologists and other scientists do every day, this horror story could become a reality. We will explore the impact of coffee rust on coffee, with an introduction to coffee and how it’s become such an integral part of our lives.
