Spore Spread
This natural force can carry wheat rust spores over long distances
What is wind
What fungus causes wheat stem rust
Puccinia graminis
what resistance gene did Ug99 overcome
Sr31
Field A is infected. Field B lies downwind, while Field C lies upwind. Which field should you team investigate first.
What is Field B
How can stem rust spores travel long distances
What is wind
Because the disease can spread quickly and damage large amounts of wheat
Why does spore arrival not automatically mean that a wheat field will develop stem rust.
What is infection also depends on host susceptibility and environmental conditions
What part of the wheat plant does stem rust commonly damage
Why is Ug99 a concern for global wheat production
Because it can overcome important resistance genes and cause severe crop losses
