    5 of 5 Stars  watermelon growth

    Verified Purchase

    I bought the rot-stop to add calcium to my soil for watermelons that were growing to an inch long, turning black and dying. After using rot-stop my watermelons are now developing and I have more than the past two years. I also use it on my tomatoes and those plants look fantastic with many tomatoes. I will start harvesting the first ones next week and so far no end rot.

August 1, 2012Gina from Chicago, Il asked:

QWhat are the other inactive ingredients in Bonide Rot-Stop Tomato Blossom End Rot?

AWe contacted the manufacturer and they informed us that the active ingredient contained in the Bonide Rot-Stop product is not allowed in organic garden. They could not share the information on the inactive ingredient as that is proprietary information that the manufacturer will not share with anyone, including Do My Own Pest Control.

QMy tomatoes have Blossom End Rot, and I heard that it helps to use a 4-12-4 fertilizer. What would you suggest?

ABlossom end rot is caused by a calcium deficiency which can be aggravated by too much nitrogen in the soil. So it's not generally recommended to add any additional nitrogen when treating for end rot. Bonide Rot-Stop Tomato Blossom End Rot is our most popular product for blossom end rot.
