Integrated Pest Management Options
Stripe rust can be confused with Cephalosporium stripe since both
will produce a yellow striping (interveinal) that can extend the
entire length of the leaf. If rust is the cause, orange-yellow pustules
(blisters) can be found, whereas no blistering is found in Cephalosporium
stripe. This disease is most noticeable in seasons with a prolonged
cool spring (3°C-15°C). Symptoms often disappear as temperatures
increase.
| Active ingredient |
pyraclostrobin |
| Trade name |
Headline EC |
| Rate per hectare (product) |
400-600 mL per ha |
| Rate per acre (product) |
160-240 mL per ac |
| PHI* |
Do not apply at boot stage and beyond. |
| Comments |
Ground and aerial application. Apply only up to flag leaf
fully emerged stage (Zadoks 39). Do not apply at boot stage
(Zadoks 47) and beyond. Maximum 2 applications/yr. 12-hr re-entry
period. |

Quilt |
| Rate per hectare (product) |
0.75–1.0 L per ha |
| Rate per acre (product) |
305–406 mL per ac |
| PHI* |
Do not apply at boot stage and beyond. |
| Comments |
Ground and aerial application. Apply only up to flag leaf
fully emerged stage (Zadok's 39). Do not apply at boot stage
(Zadok's 47) and beyond. Use higher application rate of 1 L/ha
when expecting high disease pressure from stripe rust and wheat
leaf rust. Maximum 1 application/yr. Do not harvest for forage.
12-hr re-entry period. |
| Active ingredient |
propiconazole |
| Trade name |
Tilt 250 E |
| Rate per hectare (product) |
500 mL per ha |
| Rate per acre (product) |
200 L per ac |
| PHI* |
45 |
| Comments |
Ground and aerial application. Apply at early signs of disease
from the beginning of stem elongation (Zadok's 29-37). If conditions
favourable to disease continue, apply again, if necessary, before
head is half emerged (Zadok's 49-55). Can be tank-mixed with
several cereal herbicides. Maximum 2 applications/yr. |

| Active ingredient |
tebuconazole |
| Trade name |
Folicur 250 EW |
| Rate per hectare (product) |
375-500 mL per ha |
| Rate per acre (product) |
152-200 mL per ac |
| PHI* |
36 |
| Comments |
Ground and aerial application. Apply to leaf foliage at the
first sign or very early stage of disease, especially if weather
conditions are conducive to disease development, up to the
end of the flowering stage. Use the higher rate when weather
conditions are conducive to heavy disease development. The
use of a non-ionic surfactant (Agral 90 or Agsurf) is NOT
required as it is built into the formulation. Use a minimum
of 100 L/ha of water for ground application, 47 L/ha of water
for aerial application. Maximum 1 application/yr. 12-hr re-entry
period.
Before using Folicur for wheat leaf diseases, consider
that Folicur can only be applied once/year and has been traditionally
used for Fusarium control, where applications are targeted
at head emergence.

Folicur 432 F |

220-292 mL per ha |

conditions are conducive to disease development, up to the

conditions are conducive to heavy disease development. Use
non-ionic surfactant such as Agral 90 or Agsurf at 0.125%
vol/vol. Use a minimum of 100 L/ha of water for ground application,
47 L/ha of water for aerial application. Maximum 1 application/yr.
