Biology Questions
 Do other countries have sentinel plots? (5/16/2006)
 Is there a strategy for posting information about the advance of Asian soybean rust during the growing season? Is there a strategy for posting the results that are coming from the sentinel plots? (5/16/2006)
Can rust wipe out soybean fields under hot, humid conditions? Is infection mostly a function of rainfall and moisture, or how does UV light factor into this as well, but the main question is about the temperature, hot versus cool. (5/16/2006)
How are spores detected? Are they visible to the naked eye if they are present on the plants, and how are sentinel plots going to be observed or scouted? Could you see the spores, or what are people going to be looking for? (5/16/2006)
Could the spread of rust have been prevented? How? (5/16/2006)
If spores are so sensitive to light, temperature, etc. then how did they survive going from one continent to another? (5/16/2006)
What is the viability of rust spores when they are being transported by the wind? Does direct sunlight ultraviolet radiation, temperature, altitudes, do any of those things have an impact on the life span of rust spores? (5/16/2006)
What areas of the United States are most at-risk to yield losses from soybean rust? (5/16/2006)
Does Asian soybean rust affect any other crops grown in the North Central region? (5/16/2006)
What is the status of alternative hosts of Asian soybean rust? (5/16/2006)
Will Asian soybean rust pathogen overwinter in northern climates? (5/16/2006)
Are there areas of the world that make sense to look to in anticipating what might happen in Iowa? Are there better places to look to than Brazil to draw comparisons? (5/16/2006)
How long would it take for Asian soybean rust to be transported by wind currents from southern to northern production areas? (5/16/2006)
How far and how fast can the Asian soybean rust pathogen spread? (5/16/2006)
How does this disease affect soybean? (5/16/2006)
If we have favorable conditions initially for rust to develop, and spores are produced and moved into Iowa, and then the weather turns very hot and dry, what happens? What are the management implications of that scenario? (5/12/2006)
What does the Asian soybean rust look like? (5/12/2006)
How was Asian soybean rust carried to the United States? (5/12/2006)
Soybean rust spores were found on aphids, what does this mean? (5/12/2006)
Once I find soybean rust in one of my fields, do I need to be worried about spreading it to other fields while scouting? (5/12/2006)
Will the rust fungus be able to adapt to survive over winter once it makes it to Iowa? (5/12/2006)
Do rust infections always occur on the bottom of soybean plants? (5/12/2006)
Were rust spores found in Minnesota in 2005? Any truth to this rumor? Can’t spores be moved hundreds of miles in a day by high wind currents? (5/12/2006)
Rust in Mexico? Any truth to this rumor? (5/12/2006)
Teliospores were found in Florida. What does that mean? (5/12/2006)
With all the hurricanes in 2005, why didn’t we see more spread of the disease? (5/12/2006)
Why don’t southerners just kill kudzu or at least spray it with fungicides? (5/12/2006)
