http://orgprints.org/7413/ Research on health of organically cultivated potatoes Lenc, Leszek Sadowski, Czeslaw Nowacki, Wojciech Lukanowski, Aleksander Crop health, quality, protection In 2002-2004, the disease incidences of six potato varieties grown under organic or integrated farm practices were studied. Disease incidences were also investigated with respect to soil fungal populations and the practice of pre-germinating of tubers. Organically grown potatoes had a lower occurrence of sprout rot (Rhizoctonia solani) and common scab (Streptomyces scabies) than potatoes grown in integrated system. More saprophytic species were found in the organic rather than in the integrated system. Pre-germination of potato tubers had positive but minimal effect. There were large differences in disease susceptibility among the potato varieties tested. 2006 Conference paper, poster, etc. NonPeerReviewed rtf http://orgprints.org/7413/1/Congress_potatoes.rtf Lenc, Leszek; Sadowski, Czeslaw; Nowacki, Wojciech and Lukanowski, Aleksander (2006) Research on health of organically cultivated potatoes.
