The long term field trial continues with weekly psyllid counts. Treatments continue to have similar effects on ACP counts. The kaolin effect continues to result in differences in CLas infection. A July sampling for qPCR assesment of CLas infection indicated that there is no difference in infection between foliar insecticide and untreated control treatments with means near 75% infectction (approximately 1 year after planting). Approximately 30% of undyed kaolin plants were infected, and 15% of red-dyed kaolin plants were detected as infected. These infection results are promising, but still preliminary. Additionally plants in both of the kaolin treatments continue to show higher growth rates than the other two treatments. We harvested a small but important harvest from the kaolin treatments but not from the controls. The Master’s student funded by this project has defended his proposal has completed one experiment and nearly completed two more regarding kaolin films dyed different colors. Intitial results are that all colors reduce leaf temperature. The dyed films additionally reduce photosynthetically active radiation (PAR) below that of the white kaolin. Red produces a moderate (~30% reduction), while the other colors dramatically reduce PAR. White kaolin increased maximum photosynthesis, whle red kaolin was not significantly different from control or white kaolin. The other colors reduced photosynthesis. Both red and white result in less dramatic midday depression. We are now planning an experiment to test whether red is improving water status under water limiting conditions. A final experiment will begin in December, using similar treatments as the first potted experiment, but controling for quantity of PAR to isolate quality effects alone.
