| Abstract: | Regular and excessive rates of chlorine dioxide (ClO2) and hydrogen dioxide (H2O2) were sprayed five times at 3-day intervals on eight bedding plant and nine shrub species to determine if plant damage would result. Marketability was judged to be reduced if >4% surface area of leaves and/or flowers were adversely affected. Rates of 5 and 50 ppm ClO2 and 900 and 2700 ppm H2O2 did not damage most plants tested and will likely control most common pathogen propagules. Rates of 100 ppm ClO2 and 5400 ppm H2O2 did not damage most plants tested if sprayed less than four consecutive times and should control some of the more chemical-tolerant pathogens. |
