Here is this week’s ‘Fungicide Resistance Management Minute’ brought to you by Corteva. We’re hearing from Lindee Love, Corteva’s Strategic Account Manager in Northern California on the causes of fungicide resistance.

Q: Lindee,  what are some causes of fungicide resistance?

A: The causes can be a factor of things. It could be the severity of the disease, not rotating your different FRAC groups, not being preventative and staying on top of your program, and weather conditions. There’s a variety of things that influence resistance over time.

Q. So, what can we do to prevent it?

A. It’s important so that you’re rotating the chemistries. If you do consecutive applications with the same group, you can actually have a the disease or the pathogen build resistance, and then it will produce a new generation of pathogens that are going to keep continuing to be more resistant. Typically growers or the PCA will come up with a tentative program for the season and then, as the season goes and there’s weather conditions, rain, humidity. For pathogen to actually occur,there has to be the pathogen present, the host available and then also the correct conditions. All three of those have to be present for the pathogen to keep reproducing. The grower or the PCA through the season needs to adjust the program as necessary so they can target a specific disease.

Q: Lindee, where can folks get more information on all of this?

A: Growers could contact their local Corteva Agriscience representative or visit Corteva.US/fungicideresistance.

Thank you for all the information. That was Lindee Love with this week’s ‘Fungicide Resistance Management Minute’ brought to you by Corteva.
