CSI Meeting, ILRI Campus, Nairobi, March 31 – April 4th 2009

2. Outline
● Wheat Stem Rust Monitoring
● DTMA
● Wheat Atlas
● Wheat Blast - an emerging new threat?

3. Wheat Stem Rust Monitoring
● Development of standardized
field protocols + geo-referenced
data collection
● Centralized data base
● Improved web-based information
tools

● 3 Regional training workshops
● 100 GPS units distributed (29 countries)
● Standardized protocols

5. On-line Information Tools
● RustMapper (Google Earth/web-browser)
● Near real-time: sites, winds, wheat,
susceptibility

6. Ug99 Pathway
● Known movements are following winds
● Yemen – most likely source for Iran
● Highly likely that Ug99 went undetected
in southern Iran or southern Iraq?
● High potential for multi-directional
dispersal from Iran
● New variants likely to follow a similar
route?

7. DTMA
● All Socio-econ data geo-referenced, compiled
and summarized
● Drought frequencies – By maturity groups and
growth stage, frequencies for last 7 years
● Improved seed demand models in development

8. DTMA – New Tools
● Customized visualization tool based on Google
Maps / Google docs developed
● Google Earth version (browser) – coming soon

Where the Economists are working

10. DTMA – Trial Sites Tool
● Site checking / editing tool
● Interactive tool – real-time links into MySQL data
base
● Correct site locations – extract data for GxE

11. Wheat Atlas
● An integrated web-based compendium of useful
geographically-based wheat information
● Countries in phase 1: Algeria; Egypt; Ethiopia;
Morocco; Sudan; Tunisia; Turkey
● Draws information from CIMMYT international
trial site dbase, FAOSTAT ..
● Interactive charts, maps, tables – region /
country / site level

12. Wheat Atlas

13. Wheat Blast – An emerging threat
● Wheat blast caused by Magnaporthe grisea
● First report Paraná, Brazil in 1985
● Now found in Brazil, Paraguay and Bolivia
● Severe yield losses (90-100%)
● NO KNOWN SOURCES of RESISTANCE
● Lack of epidemiological knowledge
● Seed-borne (others?)
● Where might be at risk?

14. Potential in Other Regions
● Climate similarity
• Maximum Temperature
• Minimal Temperature
• Rainfall

15. Key Areas
● Ethiopia
● South Asia
● North America
● Need to keep a close watch on this disease
