Stripe Rust Reported in Eastern Idaho

Stripe rust has been reported in UI Pettit in the Rockford area south west of Blackfoot. 

Stripe rust has been reported in WB936 on west side of Idaho Falls.

Stripe rust has been reported in a spring feed barley (http://www.westbred.com/Products/Northwest/Barley%20Documents/WESTBRED_501.pdf) north of Rupert. The barley was in milk to soft dough. Fungicide application is not recommended for the barley, and in addition the allowable time frame has passed for fungicide application in that field. 

Spot Form of Net Blotch Affects Barley in Idaho

A new small grains alert was posted to PNWPestAlert.net.

Alert Information:
Last year, a new barley disease was seen for the first time west of Blackfoot.

This year, numerous examples have been seen of the Spot Form of Net Blotch, also called SFNB. So far, we are not able to determine damage estimates for our production conditions. In other areas where the disease occurs (Montana, MonDak areas), losses of 50-75% have been reported. Again, there are no estimates of damage potential here. Full rates of fungicides are recommended for control in susceptible varieties. The 2014 PNW Plant Disease Management Handbook lists the following fungicides for control (this list may not be inclusive of all effective fungicides): Headline (6-9 fl oz/A), Stratego (7 fl oz/A), Vertisan (14-24 fl oz/A), Priaxor Xemium (4-8 fl oz / A).
