Research Project: In Field Solar Heat Treatment of Hlb-Infected Orange Trees for Inculum Reduction; Field Trial of Thermotherapy for Citurs Huanglongbing

Location: Subtropical Plant Pathology Research

Project Number: 6618-22000-039-47
Project Type: Reimbursable

Start Date: Nov 22, 2013
End Date: Jun 30, 2014

Objective:
1. Conduct larger-scale field trials with three different locations along with different citrus varieties (a total of 180 trees) to evaluate the thermal effects on Las bacterial population dynamics, plant growth and productivity. 2. Develop a mathematical model to predict the time duration required for the best outcome, which will use the data generated from previous and future trials.

Approach:
The heat treatment will be conducted in the fields using portable greenhouse. We will use real-time PCR (Polymerase Chain Reaction) to quantify the bacterial titers before and after heat treatment, and measure yields (productivity) of treated and non-treated citrus plants.
