| Crop | Crop Management | Cultivar susceptibility to powdery mildew | Fungicide trade name | Remarks |
|---|---|---|---|---|
| Wheat | High
or expected yield > 70 bu/A |
Susceptible | Baytan 30 + Captan or
Baytan 30 + Thiram |
Does not provide full season control of mildew. Plant Baytan-treated seed no more than 1.5 inches deep. See rates in efficacy table above. Loose smut control is excellent and damping-off control is adequate. |
| Wheat | High | Moderately susceptible | Baytan 30 + Captan or
Baytan 30 + Thiram or Dividend XL (1.0-2.0 fl oz) or Dividend Extreme (2.0-4.0 fl oz) |
See Baytan remarks above. Mildew protection with Dividend tends to decline earlier in spring than with Baytan. Higher rates of Dividend are more effective against mildew and last longer. |
| Wheat | High | Moderately resistant
or Resistant |
See remarks | Powdery mildew management with seed treatment is not required. Select any of the products listed in the efficacy table except Flo-Pro IMZ, which is a specialty product for barley stripe management. Targets are loose smut and damping-off management. |
| Wheat | Moderate or expected
yield 50 to 70 bu/A |
Moderately susceptible
or Susceptible |
Baytan 30 + Captan or
Baytan 30 + Thiram or Dividend XL (1.0-2.0 fl oz) or Dividend Extreme (2.0-4.0 fl oz) |
Powdery mildew management with these seed treatments can produce a yield response in disease-favorable years. See Baytan comments above. Mildew protection with Dividend tends to decline earlier in the spring than with Baytan. |
| Wheat | Moderate | Moderately resistant
or Resistant |
Dividend XL
(0.5-1.0 fl oz) or Dividend Extreme (2.0 fl oz) Any Raxil formulation Any Vitavax formulation |
With this combination of management and resistance the higher level of mildew protection is not warranted. |
| Wheat | Low | Any level | See remarks | Select products primarily for loose smut and damping-off control. |
| Barley and oats | N/A | N/A | See remarks | Select products primarily for smut and damping-off control |
