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 کاملAntagonistic Activity of Fructoplane Yeast Against Ulocladium Rot of Papaya
Debaryomyces hanseniZopf isolated from the fructoplane of apples were found to be effective as biocontrol agent against rot of papaya caused by Ulocladium. chartarum(Pr.) Simm. The ability of D. hansenii to prevent infection of U. chartarum was lost when the antagonist cells were killed by autoclaving. Cell free culture filtrates of antagonist were unable to prevent disease incidence. Efficacy ...
متن کاملCharacterization of biocontrol activity of two yeast strains from Uruguay against blue mold of apple
In the present study, two yeast antagonists, Cryptococcus laurentii (strain 317) and Candida ciferrii (strain 283) isolated from the surface of healthy apples, controlled blue mold of apple caused by Penicillium expansum. Both antagonists reduced the incidence of blue mold by 80% at 25 °C. At 5 °C C. ciferrii (strain 283) maintained the efficacy of disease control, but C. laurentii (strain 317)...
متن کاملBlue Diode and Red He-Ne Lasers Affect the Growth of Anthocyanin Producing Suspension Cells of Apple
Light is an effective factor in cell suspension culture and must be controlled for optimizing cell growth. Growth of anthocyanin producing suspension cells of a red-fleshed genotype of apple (RFA) was assessed in response to blue diode laser (BDL) and red He Ne (RHNL) laser. The suspension cells in L-shaped test tubes were exposed to short-term laser radiation for 20 min in a rotary shaker. The...
متن کاملEnhancement of the performance of Candida saitoana by the addition of glycolchitosan for the control of postharvest decay of apple and citrus fruit
At a concentration of 0.025% (w/v) chitosan-chloride inhibited spore germination of Botrytis cinerea, Penicillium expansum, and Candida saitoana. In contrast, at 0.5% (w/v) glycolchitosan inhibited spore germination of B. cinerea and P. expansum, but not the growth of C. saitoana in vitro or in apple wounds. The combination of C. saitoana with 0.2% glycolchitosan was more effective in controlli...
