Research Project: Nitric Oxide Fumigation for Postharvest Pest Control on Fresh Commodities

Location: Crop Improvement and Protection Research

Project Number: 2038-22430-002-05-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 30, 2017
End Date: Sep 30, 2019

Objective:
Evaluate effects of nitric oxide fumigation on postharvest quality of fresh fruit including table grapes and navel oranges.

Approach:
To utilize a cooperative effort between USDA-Agricultural Research Service (ARS) and University of California Davis (UCD) to develop nitric oxide fumigation treatments for pests on harvested table grapes and navel oranges. ARS will focus on developing effective treatments against pests. UCD will focus on testing the selected treatments on table grapes and navel oranges to determine their effects on postharvest quality. Quality assessment before and after fumigation will include the following: Table grapes: rachis browning; berry browning; berry firmness; berry shatter; total soluble solids; and titratable acidity; orange: peel damage, peel firmness, soluble solids content, and titratable acidity. For both fruit, volatile concentration will be measured, including, but not limited to, ethanol and acetaldehyde.
