Wheat powdery mildew
| Contributor: | Wageningen University & Research |
| Date Compiled: | 2025 |
Prevention
| Solution | Production stage (if possible with reference to BBCH scale) |
|---|---|
|
Wide crop rotations
|
Pre-season
|
|
Bury previous crop residues
|
Pre-season
|
|
Strip cropping (oats)
|
|
|
In case of infection, clean up crop residue to prevent overwintering of mildew. In case no major pests or diseases, leave residues in the field to improve soils.
|
|
|
Plant non-dense, for example 225 plants/m2 because dense vegetation may be conductive for spread of disease
|
|
| Solution |
|---|
|
Use resistant varieties, such as Zhengmai 366, Zhoumai 18, Zhengyumai 9987, and others.
|
|
Selection of resistant plant material
|
Monitoring
| Solution |
|---|
|
Tripping threshold: 10-12 pustules evenly distributed on the last 2 leaves.
|
|
Scouting (only apply fungicide if mildew incidence is >10 to 25%)
|
Control
