Abstract
The invention induces an increase in the resistance of potato plants, without apparent toxicity for the plant. Preliminary experiments indicate that the increase in metabolism of plants efficiently fosters (above 60%) the reduction of the development of the pathogenic phytobacteria, Erwinia carotovora, one of the principal agents in causing diseases in potatoes.
