Rust in Orchardgrass Hay Fields:

There are numerous grass hay fields and pastures this summer with rust diseases.  Second cutting orchardgrass seems to be the most affected grass species. Here are some comments by Cindy Ocamb, Botany and Plant Pathology Extension Specialist:

 “Orchardgrass can be affected by rust diseases, three to be exact; crown rust, stem rust, and stripe rust.   A sample submitted to the OSU plant clinic would be the best way to determine which rust is occurring in the orchardgrass hay fields.”

  Here's the Plant Disease Handbook link to rust in grass seed crops http://pnwhandbooks.org/plantdisease/grass-seed-rusts

“Unfortunately there are no fungicides labeled for grass hay crops or pasture.  As can be seen from the handbook, products are only labeled for use on grass grown for seed.”

If irrigating, water in the morning so that grass plants have time to dry during the afternoon and evening.  Rust diseases can increase with moisture so make sure plants are dry before night time.
