Project Type: Trust

End Date: Sep 30, 2012

Objective:
The goal of this research is to develop chamber fumigations that facilitate the movement of CA citrus through trade and marketing channels. Several contemporary trade barriers restrict, or possess the potential to restrict, foreign commerce of CA citrus, including: red scale to Korea, bean thrips to Australia/New Zealand, and western flower thrips to Taiwan. An additional feature involves the determination of the insecticidal efficacy of Vaporphos to Asian citrus psyllid via collaboration with FL scientists.

Approach:
Quarantine pests related to these trade barriers will be targeted with the Horn method of using high concentration phosphine fumigant, registered in the US as Vaporphos (Cytec), at temperatures that will not break the cold-chain of the fruit in storage (<5 C). This method is being used successfully by our Chilean reciprocal-trade counterparts, albeit on different insect pests, in citrus exports to Korea, New Zealand, Taiwan, and many other countries.
