Field Crops and Vegetables: Apply 8 to 16 ounces (230 to 460 grams) per acre during periods of rapid growth or nutritional stress. The application may be repeated 2 or more times through the growing season.
Tree Crops: Make an application of 16 to 32 ounces (460 to 920 grams) per acre 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 32 to 64 ounces (920 to 1840 grams) per 100 gallons of water.
Grapes and Berries: Make an application of 8 to 16 ounces (230 to 460 grams) per acre after active growth begins. The application may be repeated at intervals of one week or more through the vegetative‑growth period.
