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.

 

Active ingredient azoxystrobin + propiconazole
Trade name 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 propiconazole
Trade name Bumper 418 EC
Rate per hectare (product) 300 mL per ha
Rate per acre (product) 121 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.

 

 
Active ingredient tebuconazole
Trade name Folicur 432 F
Rate per hectare (product) 220-292 mL per ha
Rate per acre (product) 90-118 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. 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. 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.

 

 
Active ingredient trifloxystrobin + propiconazole
Trade name Stratego 250 EC
Rate per hectare (product) 500 mL per ha
Rate per acre (product) 200 mL per ac
PHI* Do not apply at boot stage and beyond.
Comments Ground and aerial application. Do not apply the second application within 14 days of the first. Apply only up to flag leaf fully emerged stage (Zadok's 39). Do not apply at boot stage (Zadok's 47) and beyond. Can be tank-mixed with Buctril M in wheat. Maximum 2 applications/yr. 12-hr re-entry period.

 

 
Active ingredient prothioconazole + tebuconazole
Trade name Prosaro 250 EC
Rate per hectare (product) 800 mL per ha
Rate per acre (product) 324 mL per ac
PHI* 36
Comments Ground and aerial application. Use a minimum of 100 L/ha of water for ground application, 50 L/ha of water for aerial application. Maximum 1 application/yr. 12-hr re-entry period.
