The Ferti-Lome Yield Booster label states the following: Mix 2 tablespoons (1 fluid ounce) with 1 gallon of water to stop blossom-end rot. Apply as a uniform spray to foliage and developing fruit. Make a spray application once every 7 days until 3 or 4 applications have been made. Apply in early morning when temperatures are cool to avoid burning foliage. Do not apply to plants under stress conditions. Regular spraying throughout the season is not recommended as these prolonged spray programs can cause foliage burn.
