Rating Fusarium Damaged Kernels (FDK) in Scabby Wheat

1. Wait at least a week or so after harvest (grain should be allowed to dry in the greenhouse).

2. Mix the grain in the bag as light (i.e. damaged) grain will settle on top (use a gloved hand to stir)

3. Scoop a subsample into a 60 x 15mm petri dish (or some other flat dish). (Fill dish so top is level)

4. Use scale below to estimate where your subsample fits into the scale.


5. Record FDK %. Dump grain back into bag.

6. Repeat 2‐5 until you have 5-10 FDK readings for each bag of grain.
