In the upper Midwest this year a fungal infection known as late blight is decimating gardens. It affects nearly everything, from cucumbers and melons to potatoes, tomatoes, and peppers. If you can learn to recognize the telltale signs of a blight infection before it gets a hold over your garden, then you have a chance to beat it back. If not, then you can expect to watch a large number of your plants die and your vegetables rot on the vine.
Once plants are infected with the disease it’s too late to save them, but you can take other measures to keep your garden safe. The blight fungus needs wet foliage in order to get a foothold, so watering with soaker hoses or drip irrigation can help to keep it out of your garden. You can also use a preventative spray like Actinovate, which has beneficial bacteria that can fight off fledgling blight outbreaks.
Depending on your area, blight season is either already in full swing or just getting started. So if you see the signs of late blight in your garden, pull up the affected plants immediately before it can spread.
