Abstract/Contents:"Six rates (0, 0.5, 1, 2, 5, 10 Mton/ha) of calcium silicate slag (20% Si) were evaluated in a greenhouse in relation to resistance to gray leaf spot (Magnaporthe grisea) in the St. Augustinegrass cultivars Floratam and FX10. Components of resistance evaluated were incubation period, latent period, lesion number, lesion size, percent disease, and spore number per lesion. Lesions in FX10 did not produce spores in any treatment. Silicon treatments had no significant effect (P = 0.05) on the incubation period or latent period in either cultivar nor spore number per lesion in Floratam. Lesion number was significantly reduced when compared to the control by all Si rates in Floratam and 5 and 10 Mton/ha rates in FX10. Percent disease was significantly lowered compared to the control in Floratam with 1, 2, 5, 10 Mton/ha rates and 0.5, 1, 5, 10 rates in FX10. Lesion size was not reduced by silicon in Floratam, but was reduced when compared to the control with the 10 Mton/ha rate in FX10."
