Bonide Rot-Stop Ready-to-Use (32 fl oz)

Bonide Rot-Stop Ready-to-Use is a 1.6% calcium foliar supplement for tomatoes, cucumbers, melons, and peppers. It supplies calcium derived from calcium chloride to help correct deficiencies associated with blossom-end rot. The 32 fl oz trigger bottle requires no measuring or mixing and is convenient for spot treatment in beds or containers. Apply the product undiluted, spraying foliage and developing fruit to the point of runoff during rapid growth or after excessive rainfall.

Apply in early morning or evening. When conditions favor the disorder, repeat at 5–7 day intervals. Do not use as a continuous spray program or apply excessively, because prolonged spraying can burn foliage. Keep soil moisture consistent, and use Rot-Stop as a supplement to a regular fertilization program. Store upright in the original container away from children and pets.

How Bonide Rot-Stop Ready-to-Use (32 fl oz) fits a fertility plan

• Supplies supplemental calcium for labeled vegetable and fruit uses where calcium management is part of the crop program.
• The concentrate or ready-to-use format shown in the title helps gardeners choose the preparation method that fits their application.
• Works best as one component of consistent irrigation, healthy roots, and balanced fertility rather than as a remedy for every cause of fruit damage.

Application guidance: Read and follow the product label for crops, timing, dilution, spray coverage, protective equipment, and harvest restrictions. Diagnose the cause of symptoms before treatment; drought stress, waterlogged roots, salinity, or root injury can limit calcium movement even when calcium is present.
