WPC Webinar on March 18th: Dr. Leah Tsror on Powdery Scab – Integrated Disease Management for Reducing the Risk

The World Potato Congress is extremely pleased to be offering its third webinar in 2020 featuring Dr. Leah Tsror.

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 focus will be on the epidemiology of the disease and the integrated management practices for reducing the risk of powdery scab.

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.
