Chemical control of wall vegetation - neutralisation of herbicides,Preservation Restauration des Biens Culturels,Montreux.http://hdl.handle.net/10400.8/4079The chemical control of limestone-growing wall vegetation has to be made carefully, to prevent damage caused by acid herbicides. The results obtained with a new methodology of herbicide neutralisation by potassium hydroxide are here presented.
