Sunflowers, sclerotinia and fungicides

Posted: July 31, 2015

Sclerotinia can be a devastating disease and in sunflower it is highly dependent on weather conditions.  Sclerotinia Head Rot infection is dependent on the ascospore infection.

What causes sclerotinia head rot?
Wet soil conditions over a period of 10 to 14 days stimulate the sclerotia dropped from a previous crop to germinate creating tiny mushrooms. These mushrooms produce apothecia or tiny spores which can be wind-blown to nearby fields.

The spores need dew or rain and dead or senescing plant tissue such as dead florets to germinate and infect. Wet and cloudy conditions are necessary for the disease advancement.

Like canola, there is a specific application window recommended for sclerotinia fungicide control.

Bee and sunflower

REMINDER: Producers are encouraged to take the appropriate steps to reduce risk to honey bees when spraying insecticides. This is for the benefit of both sunflower growers and beekeepers.

Important steps include:
1. Scout fields for seed damaging insects and beneficial insects, only apply insectides if necessary.
2. Spray in the evening when honey bees have returned to the hive and communicate with bee keepers.
3. Select insecticides that provide effective control of the targeted pests while minimizing impact on bees.
4. Communicate with beekeepers in your area. Honeybees can increase both the number and weight of sunflower seeds through increased pollination
