|Abstract: ||We demonstrate a simple analysis based on generic epidemiological processes to quantify
the efficacy of Trichoderma harzianum to control damping-off disease caused by Rhizoctonia solani.
The method quantifies the rate at which disease is transmitted in a population of plants, and we use the
reduction in disease transmission as a measure for efficacy of the control agent. Using epidemics in
replicated microcosms we show how the method can be used to quantify i) a reduction in the
secondary transmission rate; ii) the effect of soil type on the efficacy of biocontrol and iii) the effect of
the timing of the application on the efficacy of biocontrol.|
