General Information

MagPhite is a unique, concentrated liquid nutrient supplement for a wide variety of crops, including fruit, vegetable, ornamental, turf and field crops, for both leaf foliar and soil application. The active phosphorus ingredient, in MagPhite, is in the H3PO3 form, and is derived entirely from pure phosphorous acid.

Application Recommendations:

MagPhite can be applied as a foliar spray or as a direct soil application, with either ground sprayers or applicators, including chemigation, or with aerial application equipment. For aerial application apply 1-3 pints per acre, in a minimum of 20 gallons of low TDS (total dissolved solids) water, per acre only. For ground sprayer application, apply 1-4 pints per acre. Do not exceed by volume, a 2% (i.e. 2 gallons per 100 gallons of low TDS water). Combinations with other agricultural chemicals, including other liquid plant nutrients, and pesticides, for application efficiency; may be possible, but a small jar compatibility test should first be made before making commercial applications to the crop. A small portion of the crop should then be treated first, in order to determine phytoxicity if any.

Limitations, Restrictions, and Exceptions

ORNAMENTAL CROPS—As a post planting drench, apply 1/2 – 1 ounce per 1,000 square feet of actual crop area in a minimum of 50 gallons of drench water.
