Abstract
Potato seed tubers were dressed with the chemicals: Vitavax 200 FS, Monceren 12,5 DS and Monceren 250 FS 2–3 days before planting. Field trials were carried out in a randomized complete block design. Each plot of 25 m2 size was replicated four times. After harvest, 10 kg samples of tubers (from each plot) were washed and visually assessed for diseases. Tuber were scored for: black scurf (Rhizoctonia solani), common scab (Streptomyces scabies) and silver scurf (Helminthosporium solani). The results showed that all the tested chemicals were efficient in the black scurf control in the years 1999 and 2001 (statistically significant).
