  • Angular leaf spot symptoms & spread 05/20/2013
    Angular leaf spot symptoms are distinct and easily diagnosed. Small water-soaked lesions develop on leaves and expand until they are delimited by larger secondary veins in leaves resulting in angular lesions. After time these lesions turn brown and infected tissue drops-off resulting in 'shotholes'. Angular leaf spot can be spread by splashing rain, insects, on the hands of workers and on farm machinery. Working in the field when the foliage is wet favors the spread of the disease. The disease can also be spread by blowing wind and in irrigation water. Management of angular leaf spot begins with clean-seed and planting in fields that has been out of cucurbit production for at least 2 years. Cultivating when foliage and soil are wet and irrigating with pond water should be avoided. There are cucumber varieties with resistance. Add label rate of fixed copper + mancozeb to fungicide maintenance program and repeat applications every 7 days.

  • Fighting new strains of late blight 05/20/2013
    Late blight isn't an annual problem for Wisconsin growers, but it does make a presence in potato fields occasionally. Researchers at the University of Wisconsin-Madison (UW-M) have recently seen new strains of the disease developing in the state, prompting them to undertake a comprehensive study to find resistance before it becomes a serious epidemic. Read more on their fight from this Spudman article.
