Abstract: TYLCV is a major limiting factor for tomato production in south Florida. There is no single method which provides adequate control of TYLCV on tomato. In the greenhouse assays, Actigard® at 3 mg/1, plant growth-promoting rhizobacteria (PGPR) strains SE34 and IN937b at lxlO7 CFU/ml, and silicic acid at 1.5 mM and 0.15 mM applied as soil drench significantly increased plant height when compared with the nontreated control. SE34, IN937b and silicic acid significantly increased stem caliper, and IN937b increased the chlorophyll content in the leaves of tomato seedlings. All treatments with disease resistance inducers significantly reduced disease severity of TYLCV compared to the nontreated control. In the field trial, tomato plants treated with Actigard® at 3 mg/1 had significantly less disease than the nontreated control plants 4 weeks after transplanting.
