Effect of three antitranspirant films on Botrytis cinerea activities in vitro

Abstract EN

This work deals with the effect of the antitranspirant films folicote, nu film p and vapor gard on isotrytis cmerea activities in vuro.

vapor gard was fungitoxic to the conidial germination and the mycelial growth of the fungus when it was incoiporated to the medium.

however, as a film, it did not prevent the penetration of the fungus in the medium.

in contrast, folicote and nu film p have no fungitoxic effect.

furthermore, nu film p enhanced the fungal extracellular esterase activity induced by juniperic acid.

this enzyme release was nullified by folicote.

mode of action hypotheses related to cutinase released by fungi to penetrate plant cuticle was discussed.
