Dr. Michael Wunsch is a Plant Pathologist at the Carrington Research Extension Center at North Dakota State University. He holds a Ph.D. from Cornell University in 2010, and has worked for NDSU ever since, focused on disease management problems on a wide breadth of crops grown in North Dakota. In this episode, Wunsch provides us with a lot of helpful details about Ascochyta Blight of chickpea, including some of the historical impacts of the disease, how it spreads, the range of hosts, the process to diagnosing it, and how we distinguish it from another common pathogen called Botrytis. Stay tuned for part two of this conversation where we will discuss how to optimize fungicide applications for this disease.

“ You have some degree of Ascochyta in that field, whether it's catastrophic level or a trace level. Those chickpea residues, they're lying in that field, especially now that we're no-till and none of them are buried. They overwinter and that overwintering cycle induces the pathogen to form a different type of fruiting structure, which enables the pathogen to more quickly overcome management tools, whether that's host resistance or fungicides. And this produces spores that actually are emitted with some degree of force and they will get taken up by air currents and they can move hundreds of miles.” - Michael Wunsch, Ph.D.

This Week on Growing Pulse Crops:

• Hear from Dr. Michael Wunsch, a Plant Pathologist at the Carrington Research Extension Center at North Dakota State University.
• Explore more details about the life cycle, hosts, and diagnosis of Ascochyta
• Understand the differences between Botrytis and Ascochyta and the significance in making the distinction between the two

Dr. Sabine Banniza is a professor of pulse crop pathology and a member of the Crop Development Centre (CDC) at the University of Saskatchewan. Her research program is focused on pulse crop pathology with particular emphasis on problems in Saskatchewan. The overarching theme of Dr. Banniza’s research program is to study the biology of fungal and bacterial pathogens and their interaction with host plants.

In today’s episode, Dr. Banniza focuses on two important diseases in lentil: Anthracnose and Stemphylium blight. She is an expert on the pathogen biology and plant-pathogen interactions, and she gives us a lot of useful background on when they first started appearing in Canada, how problematic they are, and how to diagnose and manage each of these.

“ Using all of the molecular tools we have now, we’re trying to get that resistance from the wild relative into our cultivated species, and then breed race zero resistance as well. Because I think that will help a lot, and it’s really needed in particular now that we see these issues with fungicide insensitivity .” - Sabine Banniza, Ph.D.

Kyle Okke is an independent crop consultant in Dickinson, North Dakota with his own company, Agile Agronomy. Before starting Agile Agronomy three years ago, he had worked for several years as a regional agronomist in the area with Winfield United. Kyle deals with a wide variety of crops in his area including pulse crops, specifically lentils, chickpeas and field peas. He also has farmer clients that grow durum, wheat, flax, canola, corn, soybeans and sunflowers. In this episode, he discusses the various details about products, timing, water rates, adjuvants, and other considerations for controlling broadleaf weeds.

“ You get what you get as far as options for broadleaf control in pulse crops. So there's no perfect product in a broadleaf sense on a post emergent basis. So you're never always going to have excellent activity in everything. That's why there's so much emphasis on fall residuals and spring applied residuals, because that's going to do a lot of the heavy lifting for you that hopefully either you don't apply post-emerge products, or if you do, you keep the weeds small enough that you get the activity you need out of those post-emerge broad leaf products.” - Kyle Okke
