Please can wheat take-all disease resistance be added under fungal disease resistance, however, I'm not fully confident on correct usage of these disease resistance terms - I want to describe measures/estimates of disease incidence per unit area based on field observations. Is incidence synonymous with your use of resistance here?

Causal agent

Gaeumannomyces graminis var. tritici_

Symptoms

from AHDB
The take-all fungus attacks the roots of plants as it is soil-borne. If diseased plants are pulled up, the roots can be seen to be blackened and rotten and have a "rat-tail" appearance. In severe outbreaks the base of infected plants may also show blackening. Above ground symptoms are seen as patches of stunted plants and white-heads ("bleached" ears) in mature plants. White-heads generally contain small grains or, occasionally, no grain at all.
