Plant growth and the occurrence of rhizoctonia disease on Red Pontiac
and Kennebec cultivars were slightly different in Uruguay and Canada.
In both countries, use of rhizoctonia-infested seed resulted in some d
ecreases in emergence and stem number and also increased the presence
of black scurf on progeny tubers for Kennebec but only in one case for
Red Pontiac. Use of the fungicide thiabendazole as a fungicide seed t
reatment prevented some of these problems but caused some delays in pl
ant emergence and increases in stem numbers. The impact of these and o
ther observations on the export of potato seed are discussed.
