Is a buffered calcium phosphate solution for foliar application used to improve the quality, shelf life and storability of horticultural crops.
Campbells Calphos is used as a supplementary foliar spray for fruit and vegetables that suffer, or have the potential to suffer, from calcium deficiencies. Its use on pip fruit is particularly important for export fruit since the potential for apples to develop storage problems such as bitter pit are very high in many varieties.
Campbells Calphos is used in apples early to mid season, beginning about 7 days after petal fall, as part of a season long calcium program. The unique buffering system virtually eliminates any burning effect when applied at recommended rate.
Campbells Calphos is recommended for foliar application. Rates of application vary between 5-15 L/ha. Specific rates will depend on the crop, stage of crop development and application method. See the Product label for comprehensive information on rates and application methods. Foliar applications should be avoided during extremes of climate and during flowering. Before application seek advice from your Campbells Calphos distributor or your local agronomist.
