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…)
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…)
Wisconsin leads the nation in both dairy and vegetable production; these industries are keys to Wisconsin’s economy. They are also vital components of a healthy diet! It’s not surprising that in the early days of farming in Wisconsin, vegetable production and dairy cows were frequent partners in the farm economy. Modern day challenges, however, have inevitably led to more specialization in agricultural systems. With the need to increase production efficiency to meet the food needs of an increasing human population, it’s not a surprise that specialization occurred, and it’s no wonder why these two important staples of early farms drifted apart.

As spring ripens into summer and you take a relaxing drive through Wisconsin’s Central Sands—from Coloma to Plover, barely 50 miles—you will see a remarkable diversity of crops taking shape on the landscape. Not many realize it, but you are travelling through the heart of one of the nation’s most important vegetable production areas, and also one of its most diverse. (more…)
