Late blight caused the Irish potato famine in the 1840s and 1850s.
This disease and its related problems caused massive hunger, starvation and poverty, resulting in mass emigration from the region. This disease is still a concern today.
The fungus which caused the Irish potato famine is still active today. It was identified in Portage County just last week. It can cause serious problems for potato, tomato, eggplants and other solanaceous crops today. Phytophthora infestans (“infests”) is the cause of potato late blight. It is a fast moving, community disease that growers, home gardeners and garden center managers must take seriously and properly manage to ensure a healthy, adequate food supply.
There are many concerns for Wisconsin vegetable growers every year whether farmer or home gardener. Weather, growth problems, pests, water, market demand—but one pest problem, foliar or leaf blight, is especially challenging. This can commonly attack tomatoes, potatoes, carrots and cucumbers. These diseases cause perfectly healthy appearing green plants to break out in brown spots, turn yellow and die prematurely. Many home gardeners run to their local garden center for a remedy. But by the time leaves begin to yellow and the brown spots appear the disease may have progressed to a point where there is no stopping it.
On the farm, vegetable growers face the same threat from foliar blights every year. Potato and vegetable growers in Wisconsin have worked closely with University of Wisconsin researchers for decades, to understand the science behind that makes these blights tick. Through research, we have developed and implemented innovative disease management strategies to both avoid and combat plant disease problems. (more…)
Harvesting the bounty of the Central Sands is already underway –peas and snap beans are on the way to consumer’s plates and sweet corn, potatoes and carrots are just around the corner. As we watch and enjoy this remarkable productivity unfold, it is a good time to reflect on what makes it all possible. The Central Sands themselves and the underlying aquifer of groundwater laid down by glaciers 25,000 years ago and constantly recharged by rainfall, snowmelt / runoff are the corner stones in the foundation. Maintaining the delicate balance between the water resource and the needs of everyone who uses and depends on it is an ongoing challenge that we all must be a part of so future generations will enjoy the benefits of this unique area.
One particular area of focus is the Little Plover River watershed in northern Portage County. The Little Plover is a trout stream and an important drainage outlet that meanders its way westward from its headwaters east of the ancient Johnstown glacial moraine through wetlands, woods, farmland, and the homes, parks, businesses, and industries of the bustling Village of Plover to its confluence at the Wisconsin River south of Stevens Point. In recent years, the Little Plover has experienced highs and lows, which have ranged from flooding and ruined basements in some years to reduced flows in others. Although the little stream has persevered through it all and remains a great place to fish and enjoy the outdoors, everyone who lives in the watershed is concerned about its future and is working to secure it.

Wisconsin’s Central Sands provides a great diversity of food crops. It is one of our country’s most important vegetable production areas, and also one of our most diverse. Our farmers do grow USDA program crops like field corn and soybeans, but the Central Sands acreage is overwhelmed by a broad mixture of vegetables and specialty crops. We grow potatoes of all kinds—russets for baking and fries, reds and yellows for salads and many other purposes (yes baking too), round whites for chips, even sweet potatoes are grown in the Central Sands. Sweet corn, green beans, peas, carrots, peppers, cucumbers and beets dot the landscape. Most of our vegetable crops are bound for processing plants (canned and frozen) within Wisconsin then distributed across the US and to other countries around the globe. Fresh vegetables are also available to you at local farmer markets and grocery stores. We are working on expanding this area of production as the market calls for them. This crop diversity provides consumers everything from crunchy pickles and spicy relish, cranberry sauces and juices to fresh table potatoes for every meal event, locally grown in Central Wisconsin. Did you know that Wisconsin is also the nation’s largest supplier of cranberries? (more…)
The harvest season is now in full swing in Wisconsin’s Central Sands. Potatoes, sweet corn, green beans, carrots, cucumbers and beets are rolling up the harvester chains and into trucks for the short journey to Wisconsin’s processing and distribution centers and then onward to consumers across the US and beyond. Another record season seems within reach in 2013 thanks to the ingenuity and hard work of the farmers—and with some help from generous early season rains! With some Central Sands potato growers surpassing 30 tons per acre (that’s more than 3,000 ten pound bags per acre), increased productivity has held overall production close to that achieved a decade ago when 28% more acres of potatoes were grown.

The Central Sands region of Wisconsin is recognized as one of the premier vegetable growing regions in the nation; potatoes, sweet corn, green beans, peas, carrots and cucumbers all rank near the top of US production. This remarkable level of success was forged by the ingenuity and hard work of the farmers who settled here generations ago, and it is enhanced by our temperate climate with warm daytime temperatures, cool nights and ample rainfall. The foundation of the region’s productivity, however, lies in its geological history, which began during the glacial ice age that encompassed Wisconsin over 15,000 years ago. Geologically, the Central Sands is a large and relatively flat glacial outwash plain with abundant sandy soil—ideal for vegetable production—that is underlain by a deep groundwater aquifer that provides the water needed for crop growth and productivity. The sandy soils deposited by the glacial lake and its residual groundwater make this region ideal for vegetable production, which provides an economic boost to the region and enables Wisconsin to be a leader in providing a safe and abundant food supply to the whole nation.
