Metalosate Calcium Usage Instructions

Shake well before use. Keep from freezing.

Dilute one part Metalosate Calcium with 20 or more parts water. Apply by a spray method and with an adequate amount of water that will provide complete coverage of the plants. Use of a non-ionic wetting agent may improve spray coverage of certain hard to wet plants. Do not apply undiluted.

Metalosate Calcium can be included in a regular spray program on crops. Consult with a Balchem representative on compatibility with other spray materials.

The rate of application will depend on the crop, stage of growth, and severity of deficiency. The maximum recommended rates are for mature, full-sized plants. Reduce the rates proportionately when spraying smaller plants. Metalosate Calcium may be used on legumes, grain crops, root crops, cucurbits, cole crops, leafy vegetables, woody and herbaceous ornamentals, deciduous fruits, vine crops, tropical and subtropical fruits, and many other crops.

Tree Crops

Make an application of 32 to 64 fluid ounces per acre (1.5 to 4.0 liters per hectare) after the beginning of active growth. The application may be repeated at 2 to 4-week intervals through the growing season. Mid- and late-season sprays directed to cover the fruit may help to reduce the effect of calcium-related disorders. For post-harvest fruit treatment, dilute at a rate of 0.5 to 1.0 gallons per 100 gallons (0.5 to 1.0 liter per 100 liters) of water.

Grapes and Berries

Make an application of 16 to 48 fluid ounces per acre (1.0 to 2.0 liters per hectare) after active growth begins. The application may be repeated at intervals of one week or more through the vegetative growth period.


Apply 1 to 2 fluid ounces per 1000 square feet (10 to 20 milliliters per 100 square meters) during periods of active growth.
