Bonide Rot-Stop Ready-to-Use supplies nutritional calcium to help correct calcium deficiencies associated with blossom-end rot in tomatoes and other listed vegetables. The 32 fl oz trigger bottle contains 1.6% calcium derived from calcium chloride and is applied undiluted—no measuring or mixing required.
Features and Uses
- Ready to spray: Apply the product undiluted as directed.
- Listed crops: Use on tomatoes, cucumbers, melons, and peppers.
- Targeted application: Spray foliage and developing fruit to the point of runoff.
- Supplemental nutrition: Intended to complement, not replace, a regular fertilization program.
How to Apply
Apply during periods of rapid growth or after excessive rainfall. Spray in early morning or evening when temperatures are lower. When conditions favor the disorder, applications may be repeated 5–7 days apart. Do not use as a continuous spray program or apply excessively; prolonged spraying can burn foliage. Maintain consistent soil moisture because uneven watering can limit calcium uptake even when calcium is present.
Avoid eye and skin contact, wash after handling, and store upright in the original container away from children and pets.
Compare calcium fertilizers and read our calcium fertilizer guide.
