STAKKO is a mixture of chelated microelements in solid form, able to prevent and reduce micro-deficiencies and in particular cupro-manganese deficiency. Manganese is an element that plays a fundamental role in the synthesis of wood, accelerating the processes of maturation and lignification of the tissues, facilitating a rapid fall of the leaves. This helps the plant to overcome the phases of stress and physiological stagnation that occur during spring frosts, herbicide and pesticide treatments, water stress caused by both excess and lack of water. The presence of microelements almost all chelated EDTA allows a rapid and greater absorption by the plant. In particular, the EDTA chelated copper and manganese are also assimilated by the wood through the lenticels. At the vegetative restart the plants will respond with a quick and prompt activity. STAKKO allows plants to react with balanced growth, especially as regards young tissues; the plants will prove to be more resistant to early temperature drops even if sudden and sudden. The use of STAKKO is also particularly useful in nurseries where the fall of the leaves is necessary before uprooting to avoid excessive transpiration in the stems, as well as the formation of rot, mold and the establishment of parasites. STAKKO proves to be indicated on fruit trees. but especially on apple. and all those crops in which the abscission of the leaf stalk from the branch takes place with difficulty.
