Application of a completely organic and bio-degradable sugar-based insulating coating to vine shoots, to prevent late frost damages

An innovative method against late frosts in vineyard has been developed at CIRIAF, University of Perugia. It consists of an organic coating made by cotton candy and straw to prevent the vine shoots freezing due to late frosts. This technique has already tested at lab-scale with very encouraging resu...
