Summary
Treatment of freshly cut seed potatoes in a 100 ppm Agri-mycin solution reduced the amount of bacterial seed-piece decay but it also reduced the rate and extent to which the wound protective layer was formed. The treatment caused abnormality in the shape of the cells of the newly formed periderm layer and the adjacent parenchyma tissue. Combining the fungicide captan with Agri-mycin in the treating solution did not eliminate the effect of the antibiotic on the formation of a woundperiderm layer in cut seed potatoes. The Agri-mycin-captan treatment increased the susceptibility of the seed pieces to surface growth by molds and to decay byFusarium spp. The antibiotic-fungicidal treatment, however, did not reduce plant emergence or size of crop produced in the experiments conducted in Maine in 1958.
