    1. Efficacy of Jack Frost Foam for Frost Protection on selected plant species R.J. McGovern; C.R. Semer IV and Lajos Pecsenka* University of Florida Plant medicine Program and Plant Pathology Department, Gainesville, Fl and * American Ag. Foam LLC, Casper,Florida

    2. Materials and Methods Two separate tests were conducted the first planted in December 2005 and the second planted January 2006 Each test was comprised of six replicates of paired plantings for each plant species in a Randomized Complete Block Design (RCBD) Plant species evaluated in test one were: Pepper, Squash, Tomato, and Watermelon. Plant Species evaluated in test two were Pepper, Strawberry, Squash, Tomato, and Watermelon All plants (as transplants) were planted at recommended spacing in a twenty foot row surrounded by a five foot buffer.

    3. Materials and Methods Temperature monitors were placed so that the temperature at the top of the canopy was recorded at three locations within a treated and non-treated plot. Two sets of temperature monitors were placed within the entire experiment. Based upon weather forecast of a freeze event the cryo-protectant foam was applied between 4:00 p.m. and 5:00p.m. of the day before the predicted frost event The plots were examined the day before and the day after a freeze event The plot was rated for plants alive and the general condition of the plot. All data was analyzed using SAS statistical software.

    4. Results The observed temperature at the meristem of the transplants under cover of the Jack Frost Foam was up to 10.7 degrees higher than observed on the unprotected transplants. Transplants under cover of Jack Frost Foam survived 10 hours of temperatures below 32 F (Test 2) Transplants under cover of the Jack Frost Foam survived temperatures as low as 22 F (Test 2)

    15. Conclusions Timely application of Jack Frost foam to vegetable seedlings protected the seedlings from frost damage. Recorded temperatures inside the foam ranged from 6 to 10 degrees higher then the temperature outside the foam.
