摘要：
The present invention relates to the use of compositions that, when applied to citrus, are capable of controlling the psyllids Trioza erytreae and Diaphorina citri, vectors of bacteria of the genus Candidatus liberibacter, which cause the disease known as Huanglongbing (HLB), deemed to be the most destructive disease currently to affect citrus crops worldwide. These compositions may contain, without distinction, or jointly, as active components, vitamin K3, soluble derivatives thereof (preferably menadione sodium bisulphite [MSB]) or sparingly soluble derivatives thereof (preferably menadione nicotinamide bisulphite [MNB]), with respective concentrations of between 0.0001 and 200 ppm, 0.001 and 10 000 ppm, preferably vitamin K3 between 0.001 and 100 ppm, MSB between 0.01 and 5000 ppm, and MNB between 0.01 and 5000 ppm. Said compositions are applied preferably by spraying to the aerial part of the plant or via the irrigation system, and may be mixed with a variety of additives, such as organic and inorganic fertilizers, insecticides, nematocides, fungicides, bactericides, acaricides or herbicides.
