Grey mould caused by Boltylis cinerea was controlled on some horticultural crops included, tomato, bean, onion and geranium ,by applying film forming polymers coating to plant foliage. In vilro, the polymers, Wilt Pruf, Vapor Gard, Bio- Film, Nu-Film17 , Masbrane and Kaolin reduced germination, growth and sclerotial viability of B. cinerea. In addition, the hydrolytic enzymes produced by B. cinerea, Exo-PolyGalacturonase (ExoPG) and Caroboxymethyl Cellulase (CMCase) were also suppressed by the polymers. The most inhibition effect of the pathogen development was obtained by Kaolin ,Nu-Film17 and Bio-Film at 1.0% concentration. Theapplication of the polymers on leaf disks as bioassay reduced disease incidence and conidiospores density of B. cinerea. Under artificial and natural infection conditions, all film forming polymers significantly reduced grey mould disease severity on leaves, stems and fruits of various crop plants when sprayed three times at three weeks intervals. Furthermore, the application of polymers on plant foliage reduced conidiospores densities of B. cinerea. Kaolin and Nu-Film1? were strongly suppressed grey mould and the pathogen sporulation at all tested plants under field conditions.
