2. What is the BC Decision Aid
System?
• DAS is an online decision support system
for Tree Fruit Growers and Integrated Pest
Management Consultants.
• Identified as a priority agricultural
adaptation project in the Okanagan
Adaptation Strategies (2016) through a
program delivered by the BC Agriculture
& Food Climate Action Initiative.

3. What is the BC Decision Aid
System?
• BCDAS collects daily weather data to run
pest, disease and horticultural models.
• Provides time-sensitive pest and
horticultural information with
management recommendations
• Front page stories keep users informed
about upcoming management issues.

4. Cross Border Collaboration
• DAS originated at WSU as a result of reduced extension capacity and
increasingly more complex IPM programs.
• ~400 growers/consultants in WA use DAS on a regular basis on >90% of
the acreage.
• The value of DAS to the WA Tree Fruit industry estimated at $16.5M/yr.
• BCDAS is collaboration between the SIR, WSU (Dr. Vince Jones and his
team!) and BCTF.

5. How does BCDAS work?
• DAS collects weather data from Growers Supply and
Environmental Canada stations to run 18 models.
• Model forecasts are based on DarkSky weather
forecast data and on 10-year temperature averages.
• Users customize their list of weather stations, crops
and models.
• Conventional and organic management
recommendations are included.

6. What does BCDAS recommend?
• DAS can recommend product options and timing
for when to spray.
• DAS cannot recommend IF a spray is needed in a
specific orchard.
• Management decisions are made by the grower
and the pest manager, based on observed field
conditions.

7. User create a unique profile, choosing their weather stations and models.

8. 18 insect, disease and horticultural models

9. Detailed Weather Data, Risk Assessments and Management strategies within each model.

14. 2020 Projects
• Final year of funding for the BCDAS pilot
project
• Assess beta testing results for new models
and features added in 2019
