• Plant nutrients are generally applied as foliar sprays on fruit trees to prevent nutritional disorders of micronutrients. • Nutrient deficiencies of nitrogen, phosphorus, potassium, calcium, and magnesium can be corrected through foliar sprays. • Nutrient sprays can be applied at any time during the growing season to improve the appearance of foliage and color, size and quality of fruits. • For most fruit crops, plant nutrients are sprayed along with the regular spray program of pesticides. • The compatibility of nutrients and the pesticide chemicals should be ascertained before such mixtures are sprayed.
