Title:Postharvest Pest Control on Perishable Agricultural Commodities Using Controlled Atmospheres and Pure Phosphine Treatments
Objective:
  1. Develop controlled atmosphere treatments for postharvest pest control on perishable commodities.
    1. Develop semi-commercial scale storage and ultralow oxygen combination treatment for control of western flower thrips on head lettuce.
    2. Develop semi-commercial scale storage and ultralow oxygen combination treatment for control of western flower thrips on broccoli.
    3. Develop controlled atmosphere treatment for control of mealybugs and black widow spiders on table grapes.
    4. Develop ultralow oxygen treatment for control of vine mealybug on grape rootstocks.
  2. Develop pure phosphine funigant treatments for highly perishable commodities.
    1. Develop fumigation treatment with pure phosphine for control of western flower thrips on lettuce, broccoli, asparagus, and strawberries.
    2. Develop fumigation treatment with pure phosphine for control of lettuce aphid and leafminer on lettuce.
    3. Develop fumigation treatments with pure phosphine for control of mealybugs and spiders on table grapes.

Approach: The minimum duration of pre-treatment cold storage needs to be determined in order to reduce the overall duration for completing ULO treatment and make it possible for pre-export ULO treatments. Effectiveness of ULO treatments for thrips control and their effect on postharvest quality of lettuce needs to be determined in large-scale tests. Oxygen consumption rates and oxygen demands by lettuce need to be determined in large-scale trials for commercial application. Efficacy and safety of ULO treatment for control of western flower thrips on broccoli.
