This spray contains nutritional calcium, which prevents rot and keeps plants blooming and growing their best. Apply it after a heavy rain or period of damp, humid, or otherwise wet weather. It's designed especially for tomatoes, but don't tell that to the cucumbers, melons, or peppers -- they think it's just for them, and it works every bit as well!
Rot-Stop is sold as a concentrate, and you need use only 4 tablespoons per gallon of water. Spray it right onto the foliage and fruit of your plant. A single bottle makes a whopping 8 gallons of solution, protecting your whole crop all season! It's easy and safe, and comes from Bonide, a trusted name. Highly recommended. 32-ounce bottle of concentrate; makes 8 gallons.
