Pür Cu is a liquid nutrient designed to prevent and treat copper deficiencies. Copper is indispensable to the functioning of enzymes responsible for the plant’s defense mechanisms against abiotic stresses. Copper is also essential for nitrogen assimilation and lignin synthesis in plant cell walls. Pür Cu contains amino acids obtained by enzymatic hydrolysis that stimulate the physiological processes of the plant, absorption and mobility of nutrients in the plant as well as establishing resistance mechanisms against abiotic stresses (drought, low temperature, salinity, etc.). Pür Cu can be applied to all crops based on soil or tissue analyses or as soon as deficiency symptoms appear. For more information on Pür Cu, consult your agronomic adviser.
