Few foods are as iconic as the Idaho potato, and, considering the consistent quality and production levels, the top echelon reputation of these spuds is well-earned. Idaho is the nation’s largest potato producer. 

The combination of rich soil and optimal weather provide a great environment for growing potatoes, but the task is not always an easy one.

“Potatoes are very susceptible to certain diseases,” remarked Blake Matthews, a potato grower from Oakley, Idaho. “Early blight, late blight, and a lot of insect pressure. Some of the ways we’ve dealt with those are a lot of Redox products. For instance, Mainstay Si helps to create a barrier on the leaves that sucking and biting insects can’t get through. We’ve been able to step away from fungicides because of our use of Mainstay Si in our program, to be able to make those plants almost impervious to those types of insects.

 Matthews is a fifth-generation grower who hopes his next generation will continue the tradition. To do so, he continually strives for a healthy, productive growing environment.

 “I think the keys to harvesting a good potato are, you’ve got to maintain plant health throughout the season,” he said. “That starts with soil health. You’ve got to keep that plant happy. If you can do that throughout the season and give it what it needs according to the plant samples that we pull, then we will eventually harvest a good potato.”

Idaho growers produce about one-third of the U.S. potato crop. That’s more than 10 billion pounds of spuds every year on about 300,000 acres.
