Yellow and brown spots on leaf tip

Question

On a barley farm, there are yellow and brown spots on leaf tips.

Possible causes:

• Some kind of parasite
• Weather condition
• Bad seed
  • Looks like some farms using the same seed are affected

What might be the actual cause? What could be the solution?

Answer 1

I would suggest you contact your local government agricultural authority.

It looks like the barley crop might be infected with a pathogen, such as a fungus.

It could be a form of barley rust.

Different regions of the world have different forms of rust.

Your local agricultural authority should be notified in case the outbreak poses a bio security risk in your region.
