EFFECT OF MSB ON VASCULAR FUNGAL DISEASE CONTROL AND MINERAL NUTRITION OF PROTEA LEUCOSPERMUM CORDIFOLIUM CULTIVAR 'SUCCESSION II'
Water soluble vitamin K3, or menadione derivative (MSB), has been proved to be a plant defence activator, that also enhances yields and crop quality of several plants. Research was undertaken to verify the control of this product on Botryo-sphaeriaceae fungal canker disease of Leucospermum cordifolium cultivar Succession II, as well as its effect on mineral nutrition. Fortnightly sprays of MSB and a control treatment began in November 2009, in two plantations of this Leucospermum cultivar, on La Palma island (Canarian Archipelago, Spain). The plants were tested periodically for the presence of canker, and foliar samples were taken during the vegetative stage to determine their nutrient content. MSB did not control Succession II canker, and no significant differences in nutrient content were found between treated and non-treated plants.
