Project Number: 2038-22430-001-00
Start Date: Dec 10, 2012
End Date: Sep 09, 2015
Objective 1. Low temperature phosphine fumigation under the normal atmospheric oxygen and higher oxygen levels will be studied for controlling insect pests on fresh commodities. Insects that will be studied include lettuce aphid, light brown apple moth, and codling moth. The most tolerant life stage of each pest will be identified and effective phosphine fumigation treatment will be developed to control the most tolerant life stage of each pest. Effects of low temperature phosphine fumigation on postharvest quality of fresh fruits and vegetables and the treatment will be modified to achieve effective control of the pest and safety to product quality. Objective 2. Efforts will be made to evaluate potential new fumigants or non-chemical means as they become available for postharvest pest control on perishable and stored products. Objective 3. Improved management practices will be developed for control of emerging soilborne diseases currently controlled by pesticides. Employ a range of research techniques, including but not limited to evaluation of alternative fumigants and their application techniques, crop rotation, identification of host resistance, biological control, and use of ecosystem analysis to identify microbial communities associated with improved disease control).
