WPC Webinar – Dr. Leah Tsror on powdery scab

The World Potato Congress is extremely pleased to be offering its third webinar in 2020 on March 18, featuring Dr Leah Tsror, titled ‘Powdery Scab – Integrated disease management for reducing the risk’. It will take place at 09:00 a.m. Eastern Standard Time.

Dr Tsror is a Research Group Leader in the Department of Plant Pathology, Agricultural Research Organization, Ministry of Agriculture & Rural Development in Israel. Dr. Tsror has published over 100 peer-reviewed publications and she is on the editorial boards of the journals Potato Research and Phytoparasitica (both published by Springer).

The focus of Dr Tsror’s presentation during the Webinar will be on the epidemiology of the disease and the integrated management practices for reducing the risk of powdery scab.

Powdery scab causes significant economic damage in potato production worldwide due to reduced quality and marketability of seed and ware tubers. Disease development depends on a range of factors, including inoculum levels in soil and in seed tubers, cultivar susceptibility and climatic conditions.

The presentation will discuss epidemiological aspects, e.g., the role of alternative hosts, wind-driven inoculum, latent seed infection, and environmental conditions.

It will also discuss IPM approaches, preventive measures, e.g., using tolerant cultivars, soil and seed testing; cultural sustainable approaches, e.g., selecting the planting date, applying non-woven fabric on the foliage for increasing soil temperature; chemical control, e.g. soil fumigation, and pre-planting fungicide application. 

The integration of agro-techniques and control measures is likely to be an effective way for growers to reduce the impact of the disease.

The host for the webinar series will be WPC Director, Dr. Nora Olsen ([email protected]). To register in advance for this webinar on March 18, 2020 at 09:00 a.m. Eastern Standard Time go to:
