Last year I had to get rid of all my tomatato's due to the late tomato blight. I am currently spraying my tomato'e with a spray that I purchased from Home Depot. This product contains Chlorothalonil. How to minimize the blight this season? I am spraying every 7 days and I have seen some leaves ( I removed them ) that I am confident is the Blight.

The key to preventing fungal diseases is to protect the foliage with a fungicide. Typically the spray schedule is every 7-14 days. The product you purchased should list repeat spray guidelines on the label. Follow label directions and your plants should grow through the season without problem. Hope you have a great harvest!
