The challenge

Rhizoctonia solani is an aggressive soil-borne pathogen of oilseed rape (OSR) and canola worldwide, and is implicated in the yield decline of the crop when grown with increased frequency in field rotations. The epidemiology and control of R. solani AG2-1 have not been previously investigated in UK OSR crops. Presently there are no disease resistant varieties, hence the control of the disease in OSR is currently only possible through the exclusive use of fungicides, which increases input costs and is unsustainable crop management practice in the long term. Furthermore, there are currently no seed treatments registered against Rhizoctonia diseases in the UK for OSR, highlighting the lack of up-to-date information on yield loss and contribution of the disease to current establishment losses (estimated at £30M in the worst years).

The project

This project will address the following challenges to sustainable intensification of OSR production in relation to soil-borne Rhizoctonia diseases:
1. Novel trait discovery for resistance to R. solani in OSR.
2. Increased knowledge of disease epidemiology and yield loss.
3. Improved exploitation of targeted crop protection through the use of low dose seed treatment against soil-borne pathogens for crop establishment.
4. Understanding of trait/treatment interactions in relation to root health and yield of OSR grown under different environments and disease pressures.

The benefits

This project has relevance to the wider primary crop production sector with a focus on improved soil-borne disease management and breeding for disease resistance in OSR. The ultimate output of this multidisciplinary project will be the first integrated guidelines for the control R. solani, incorporating targetted seed treatments and varietal resistance for improved disease management and protection of OSR yield.
