Hydrocooling and Hydraircooling with Fungicides for Reduction of Postharvest Decay of Peaches

Contribution à l'étude des voies de pénétration de parasites fongiques des nectarines Monilia laxa (Ascomycète-Discomycète) et Rhizopus stolonifer (Zygomycète-Mucorale)

“…Leur impact économique demeure important malgré les traitements fongicides effectués en verger (Arnoux, 1986). De plus, bien que des traitements post-récoltes donnent des résultats intéressants (Ogawa et al, 1963;Wells et Bennett, 1976;Bompeix et al, 1979, Laville et Souty, 1982, ceux-ci sont interdits en France, et le contrôle de ces deux champignons parasites est difficile.…”

Relevance of the main postharvest handling operations on the development of brown rot disease on stone fruits

“…It could be attributed to higher concentration of chlorine registered when ‘Pp100’ nectarine was treated (about 14 mg L −1 ) compared to ‘Fantasia’ nectarine (about 7 mg L −1 ). During the 1960s and 1970s several research studies were carried out on the effectiveness of the hydrocooling operation with chlorinated water on the development of brown rot, and partial or irregular reduction of decay was reported in peaches under commercial conditions. In addition, Phillips and Grendahl reported that chlorine effectively reduced brown rot decay in peaches and nectarines artificially inoculated within the range of 50–100 mg L −1 when treated for 20 min by hydrocooling.…”
