Foliar spraying of micronutrient elements such as iron, manganese, zinc, boron, and copper completes the need of fruit trees for these elements and is a very suitable method to quickly eliminate deficiencies and supply the plant's need for these elements. Fertilizer sources of these elements should be of better and desirable quality; They cause better penetration and diffusion of these elements into the plant through the surface of the leaf.
Zinc Element Time in Fruit Trees
Stone fruit trees such as peach and nectarine : from the stage of bud swelling to before the flowers open, after fruit formation, after fruit harvesting to before the leaves fall.< Fruit trees such as apples and pears: the stage of new growth; The swelling stage of the flower bud, after flowering and fruit formation, after fruit harvesting until before the leaves fall. In citrus trees, after the start of new growth in the spring and, if necessary, after flowering in grape trees. >: New growth with sufficient number of leaves until flower buds appear.
