USE OF COMPOSITIONS CONTAINING MENADIONE AND/OR ONE OR MORE DERIVATIVES THEREOF FOR THE BIOSTIMULATION OF THE NATURAL DEFENCE MECHANISMS OF PLANTS IN ORDER TO COUNTERACT, FOR EXAMPLE, THE DAMAGE CAUSED BY PESTICIDES AND HERBICIDES

摘要

The invention relates to aqueous solutions that can contain, independently or jointly, the following by way of active components: vitamin K3, soluble derivatives thereof [preferably menadione sodium bisulphite or MSB] or barely soluble derivatives thereof [preferably menadione nicotinamide bisulphite or MNB], with respective concentrations of between 0.0001 and 200 ppm., 0.001 and 10000 ppm., 0.001 and 10000 ppm., and preferably vitamin K3 of between 0.001 and 100 ppm., MSB of between 0.01 and 5000 ppm and MNB of between 0.01 y 5000 ppm. The aforementioned compositions can be used in agriculture and horticulture, preferably by spraying the aerial part of the plant or using a watering system. Moreover, said compositions be mixed with different additives, such as organic or inorganic fertilisers, insecticides, nematocides, fungicides, bactericides, herbicides.
