The effects of using seed treatments on sprouting, health condition and yield of potato

Abstract

The impact of applying Prestige 290 FS, as well as biological treatments: FZB 24 WG and Proradix WP on the infection of potato tubers by Rhizoctonia solani and Streptomyces scabiei, the sprout development rate and the yield of potato tubers of three cultivars (Cyprian, Finezja and Flaming) was studied in the years 2011-2013. The experiment was conducted in a randomized split-block method in 4 repetitions. The applied chemical treatment significantly increased the potato sprouting rate and decreased the percentage of tubers infected by R. solani when compared to the application of biological treatments, as well as not treated tubers. The treatment did not affect the infection rate of tubers caused by S. scabiei. The infection of tubers caused by R. solani did not depend on the cultivar, while in case of S. scabiei the highest infection rate was observable in case of the Cyprian cultivar. Applying both chemical and biological treatments did not affect the yield of tubers.
