Residual Activity of Fludioxonil and Pyrimethanil Against Penicillium expansum on Apple Fruit
At harvest, apple fruit are placed into wooden or plastic bins (approximately 400 kg of fruit per bin), which are then transported to storage and packing facilities. Prior to storage, fruit may be drenched with a fungicide to control postharvest diseases (10). Fruit are stored in the bins in either regular atmosphere (RA) or controlled atmosphere (CA) (1 to 2% O2 and 0.5% CO2) at –1 to 3°C (9)....
متن کاملDraft Genome Sequence of Penicillium expansum Strain R19, Which Causes Postharvest Decay of Apple Fruit
Among the species that cause blue mold, isolates of Penicillium expansum are the most prevalent and virulent species, causing more than 50 percent of postharvest decay. We report the draft genome sequence of P. expansum R19 in order to identify fungal virulence factors and to understand the mechanism of infection.
متن کاملIncrease in antioxidant gene transcripts, stress tolerance and biocontrol efficacy of Candida oleophila following sublethal oxidative stress exposure.
A pretreatment of the yeast, Candida oleophila, with 5 mM H(2)O(2) for 30 min (sublethal) increased yeast tolerance to subsequent lethal levels of oxidative stress (50 mM H(2)O(2)), high temperature (40 °C), and low pH (pH 4). Compared with non-stress-adapted yeast cells, stress-adapted cells exhibited better control of apple fruit infections by Penicillium expansum and Botrytis cinerea and had...
متن کاملEnhancement of the biocontrol agent Candida oleophila (strain O) survival and control efficiency under extreme conditions of water activity and relative humidity
The objective of this work is to evaluate the ability of some additive substances in protecting the biocontrol agent Candida oleophila (strain O) against the adverse effects of environmental factors, such as water activity (aw, 0.93 and 0.98) and relative humidity (75% and 98%). The protection obtained with various protectant substances, skimmed milk (SM), peptone, maltose, sucrose, sorbitol, l...
متن کاملBiological control of postharvest spoilage caused by Penicillium expansum and Botrytis cinerea in apple by using the bacterium Rahnella aquatilis.
The epiphytic bacterium Rahnella aquatilis, isolated from fruit and leaves of apples, was tested for antagonistic properties against Penicillium expansum and Botrytis cinerea on Red Delicious apple fruit. In "in vitro" assays, this bacterium inhibited completely the germination of P. expansum and B. cinerea spores, but it needed direct contact with the spores to do it. However the putative mech...
