Cotegra
The new standard for sclerotinia.
5 AVAILABLE
Canola
Field Peas
Lentils
Soybeans
Target yield – Understanding yield targets will help determine the potential impact of sclerotinia and help quantify the value of a sclerotinia fungicide application
Crop rotation – Seeding canola more frequently than every 1 in 3 years of a rotation or having a tight rotation with other host crops for sclerotinia (pulses) can increase risk
Commodity price – High commodity prices further benefit the return on investment (ROI) when applying fungicides
Weather – Wet conditions create the ideal environment for sclerotinia development, but morning dew and the transition from hot days to cool nights can also create high humidity in the crop canopy
Cotegra fungicide inhibits spore germination and also inhibits mycelial growth and sporulation of the fungus on the leaf surface. It can be applied in either pre- or post-infection, however, optimum disease management is achieved when it is applied preventatively in a scheduled protective spray program.

1 Dry beans include Lupinus spp. (grain lupin, sweet lupin, white lupin, white sweet lupin), Phaseolus spp. (field beans (dry common and coloured beans) such as kidney, black, cranberry, pink, navy bean, pinto bean, tepary bean, lima bean (dry)), Vigna spp. (adzuki bean, blackeyed pea, catjang, cowpea, crowder pea, moth bean, mung bean, rice bean, southern pea, urd bean, broad or faba bean (dry)).
2 Control.
3 Suppression.
4 Suppression at the low rate of 80 acres/case (0.6 L/ha) and control at the high rate of 70 acres/case (0.7L/ha).
Cotegra should be applied preventatively, prior to the onset of disease.
Rainfastness – Avoid applying when rain is forecasted within 3 hours of application.
Pre-harvest interval
36 days after application for canola, Oriental mustard and rapeseed.
21 days after application for lentils, field peas, chickpeas, dry beans, and soybeans.
Crop |
Staging |
---|---|
Canola, Oriental mustard, rapeseed |
20 - 50% flowering |
Chickpeas, field peas, lentils |
Beginning of flowering or at first sign of disease |
Dry beans1 |
20 - 50% flowering |
Soybeans |
Prior to disease development (late R1/R2 to R3) |
Note: A 2nd application can be made 7 to 14 days after 1st application if disease persists, or weather conditions favour disease development. Use the shorter interval when disease pressure is high to obtain extended protection and maximum yield benefit.
1 Dry beans include Lupinus spp. (grain lupin, sweet lupin, white lupin, white sweet lupin), Phaseolus spp. (field beans (dry common and coloured beans) such as kidney, black, cranberry, pink, navy bean, pinto bean, tepary bean, lima bean (dry), Vigna spp. (adzuki bean, blackeyed pea, catjang, cowpea, crowder pea, moth bean, mung bean, rice bean, southern pea, urd bean, broad or faba bean (dry).
One case of Cotegra fungicide will treat 50 - 80 acres, depending on crop.

4 Higher water volumes are recommended for optimal coverage.
Around mid-June before flowering, look for apothecia (golf-tee shaped mushroom structures) under the canopy. Spores are shot in the air and can move locally and in nearby fields. If you find signs of sclerotinia, it’s already too late and preventative disease control is not possible.
The ideal temperature for storing fungicides is above the freezing point at 0°C. See page 228 in the Agricultural Solutions Guide.
Nexicor® fungicide should be applied early at the 2 to 6 leaf stage. Lance® and Cotegra® fungicides should be applied at the 20-50% flowering stage.
Tank clean out recommendations can be found on the product label.
Each fungicide has one or more unique mode(s) of action, controls a different disease(s) and is applied at specific crop staging.
Nexicor fungicide controls blackleg and contains three active ingredients, including Group 3,7 and 11. It can be applied early at the 2 to 6 leaf stage.
Lance fungicide contains a Group 7 active ingredient and controls alternaria black spot and sclerotinia. Cotegra fungicide contains Group 7 and 3 active ingredients and controls sclerotinia in canola. Both of these fungicides can be applied at the 20-50% flowering stage.
No, there are no registered follow crops for Cotegra, Lance and Nexicor fungicides.
Mixing order for Cotegra® fungicide:
Cotegra fungicide:
For aerial applications, the recommended water volume for all fungicides is 20 L/ac (5 gal/c). For ground applications with Lance or Nexicor fungicides, the recommended water volume is 40 L/ac (10 gal/c). Whereas for ground application with Cotegra fungicide, the recommended water volume is 40 to 80 L/ac (10 to 20 g/ac). Higher water volume is recommended for optimal coverage.
Restrictions/conditions for Cotegra fungicide application in canola:
Cotegra fungicide is most effective when applied at the recommended 20-50% flowering stage. Applying at the late flowering stage may be too late.
