First Confirmation of 'Late Blight' in Illinois from Winnebago County
FOR IMMEDIATE RELEASE
September 9, 2013
Phytophthora infestans, was confirmed in Winnebago County on tomato on
August 30, 2013. This is the first report of Late Blight this year in Illinois
with the closest incident reported in Racine County, Wisconsin the first week
of August. "Late Blight can cause devastating damage including yield loss" says
Grant McCarty, University of Illinois' Extension Local Foods and Small Farms
Educator for Jo Daviess, Stephenson, and Winnebago Counties." "It has the
ability to spread very fast among crops like tomatoes, potatoes, and peppers.
Late blight conditions first show up as water soaked lesions on the leaves.
Fruit may also become infected overtime."
Disease management of Late
Blight includes disease scouting and preventive fungicide spraying. Once Late
Blight is diagnosed, infected plant material should be destroyed. "Prevention
is certainly the key for growers to manage disease before the season begins.
Practices can include crop rotation, removal of diseased plants/leaves,
weed/insect pest control, sanitize and clean tools used in production, and
planting disease resistant varieties." McCarty continues that "by utilizing
many of these on a regular basis, a grower can prevent many of the diseases
that affect both cool and warm season crops."
