Table A.1.

Overall detection chance of P. s. ssp. stewartii when importing seed lots when accounting for the uncertainty in the elicited proportion of infected seeds, for three sample sizes (400, 1,000 and 4,000 seeds). 10,000 Monte Carlo draws were made to represent the variation in the proportion of infected seed, based on uncertainty about the proportion of infected mother plants in the country of origin and the rate of transmission to seed

Import of seeds	Average level of infection	Sample size
		n = 400	n = 1,000	n = 4,000
Susceptible seeds only	131 per million	0.05	0.12	0.34
Resistant seeds only	0.24 per million	0.00009	0.0002	0.0009
Mixture of susceptible and resistant seeds (A0 scenario)	27 per million	0.01	0.03	0.09
