Evaluation of post-harvest application of sodium bicarbonate incorporated wax formulation and Candida oleophila for the control of anthracnose of papaya
Abstract
The potential efficacy of a combination of the biocontrol agent Candida oleophila with a sodium bicarbonate-incorporated wax coating to control anthracnose caused by Colletotrichum gloeosporioides, on papaya (Carica papaya L.) during storage was investigated. The survival of C. olephila was 100% in 2% sodium bicarbonate-incorporated wax coating for 60 min and the survival was over 90% in 2% sodium bicarbonate-incorporated wax coating for 7 and 14 days during storage at 13.5°C and 95% RH. The combined application of 2% sodium bicarbonate in wax formulation and C. oleophila (2x10⁸ cells) resulted in a significant reduction of anthracnose incidence and severity in naturally infected fruits stored at 13.5°C and 95% RH for 14 days and for additional 2 days under simulated marketing conditions. The recovery of C. gloeosporioides and C. oleophila was, respectively, low and high from fruits coated with 2% sodium bicarbonate-incorporated wax coating and C. oleophila. Thus, the use of 2% sodium bicarbonate-incorporated wax coating with C. oleophila represents a commercially acceptable alternative to chemicals for post-harvest control of anthracnose of papaya during storage.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
