Adriano Altissimo and Cristina Sudiro participated to the 16th Serbian Congress of fruit and grapevine production where Cristina Sudiro made a speech about the use of LL017, a product with a potential use in biocontrol, in protecting the grapes from downy mildew. The results were achieved in the frame of EU LIFE Project Plants for Plants® (P4P), where the biostimulant effect of 4-Vita was proved on grapevines and apples.
