Efficacy of Fungicides and Biopesticides for Management of Phytophthora Crown and Root Rot of Gerber Daisy

Fig. 2. Efficacy of phosphite salt fungicides for prevention of Phytophthora crown and root rot of Gerber daisy caused by P. cryptogea over three trials in 2007, 2008, and 2009. (B) Top weight as a percent of the non-treated, non-inoculated control for each trial date. Values are the means of eight observations per treatment except in 2009 with 16 observations per treatment. Not all treatments were tested each year; "nt" indicates missing treatments. Rates are per 100 gallons of water. "Notr inoc cntl" is non-treated, inoculated control while "Notr noinoc cntl" is non-treated, non-inoculated control. Means within a year followed by the same letter are not different according to the Waller-Duncan k ratio, t-test, k = 100, P = 0.05.
