1-Methylcyclopropene (1-MCP), an ethylene action inhibitor, was applied to ‘d’Anjou' pears (Pyrus communis L.) at 20°C between 2 and 5 days after harvest. Scald of ‘d’Anjou' pears was completely controlled by 1-MCP at a concentration between

Conditions were established for inducing pear blossom blast caused by Pseudomonas syringae pv. syringae on both attached and detached shoots. The incidence of blossom blast was proportional to the logarithm of the P.s. pv. syringae population under o

Adhesion and removal of dry and wet conidia of Botrytis cinerea and Penicillium expansum on dry and wet surfaces of grape and plum fruit were investigated. Conidia of B. cinerea adhered more strongly when applied in a water suspension or to the wet s

Phialophora malorum was recovered from orchard air during fruit harvest and from surfaces of harvested fruit in orchard bins but not from orchard air or fruit surfaces during the growing season. Propagules of P. malorum were recovered from immersion

Phialophora malorum was found in pear orchard soil over a 2-yr period. P. malorum was not a primary colonizer of fallen fruit on orchard soil, but propagule numbers increased subsequent to fruit decay by other organisms. Cankers developed when P. mal

Penicillium solitum, a species neglected in recent taxonomies, is revived. A new description and related taxonomic information are given, based on examination of a number of fresh isolates from pome fruit and wooden fruit bin surfaces in Australia an

Internal stem and root tissues of pear trees were sampled for presence of Pseudomonas syringae at seven orchards in Oregon. Isolates positive for fluorescence (F+) and negative for cytochrome oxidase reaction (Ox−) were defined as P. syringae. Endo

Vinegar flies and nitidulid beetles acquired propagules of M. piriformis and transferred them to 75-100% of injured peach fruit. In general, C. hemipterus transmitted M. p. to wounded fruit more efficiently than C. freemani. Propagules of M. p. persi

‘D'Anjou’ pear fruits ( Pyrus communis L.) were harvested at 3 times, 24 August, 8 September (commercial harvest date) and 30 September 1982. Late-harvested over-mature fruits were more susceptible to storage decay than immature and optimum-matur

Stem-end decay caused by several several fungi was less in ‘d’Anjou’ pears (Pyrus communis L.) stored in a low O2 (1% O2 + 0.05% CO2, −1.1°C) room than in ones stored in −1.1° air. Ethylene concentration in the low O2 room was about 120 t
