Crown gall has been a major problem for many growers - leading to stunted plants and reduced yields. The condition affects ornamental and fruiting plants. But despite the impact of the disease, there is no control product available to tackle it.
Nursery consultant John Adlam, who chairs the HDC crown gall technical group, will be analysing the data. The work has been given a high priority by the HTA and will be scrutinised by the HTA's hardy nursery stock panel.
The initial survey findings will be used to create policies for the control of the condition. They will also help to direct further research, which is likely to be financed by the HDC.
The survey, which is available online here, asks growers to specify which plants are affected and whether the disease is a sporadic or persistent problem. It will also try to discover what percentage of stock is damaged.
In addition, the survey looks at where the disease is found - whether in pots or open ground. And it tries to find out what control strategies are currently in use.
