Yesterday's post covered late blight on tomatoes, just confirmed in Connecticut. Today brings news of another blight. One that attacks basil … that's right … basil. I'm just full of good news!
August 11, 2009. Late blight continues to rear its ugly head in Connecticut farms and gardens, according to a recent report in the Norwich Bulletin. Because of the high risk of this windborne fungus spreading from location to location, I check my tomato plants daily. The Connecticut Agricultural Experiment Station's Department of Plant Pathology and Ecology posted images of CT grown tomatoes with late blight. For images of all types of tomato disease, visit Cornell University's Vegetable MD Online.
If your tomato leaves, stems, and buds don't look something like the healthy plants depicted in the photos at the right … and rather look more like tomatoes depicted at the Late blight on tomato site at Cornell University College of Agriculture and Life Sciences, some of your veggie growing dreams could be in for a dashing. Take the time now to study these photos … then head out to your plants and check the stems for sections of dark brown with white fungal growth, and check the leaves for brown sections with underside areas housing tiny white spores. If you see anything that looks like the photos in the link above you could very well have late blight. This is a serious fungal threat, not just to tomatoes, but to all nightshades – eggplant, peppers, potatoes. How big of a threat? Late blight is the disease that caused the Irish Potato Famine according to a fact sheet put out by Cornell Horticulture.
