Rain Damaged Grain May Offer Feeding Opportunity for Beef Producers

John B. Hall, Ph.D., PAS
Extension Beef Specialist, University of Idaho

August rains may have helped out range and pastures, but they left
behind damaged hay and grain fields. Barley that sprouted in the head and rain damaged wheat may be an opportunity for feeding beef cattle. This may partially offset losses that grain growers have incurred. Even grain that has low levels of mold and mycotoxin may be fed to beef cattle without any negative effects. However, beef producers and nutritionist need to know the mycotoxin content of feeds before purchase.
Performance of cattle fed damaged cereal grains
Several university studies have demonstrated that cattle perform well on rain damaged grains. In general, performance is not compromised when sprouted grains are incorporated into the diet on a dry weight basis (Tables 1, 2 & 4).

What to Do with Moldy Hay

by Glenn Shewmaker, Extension forage specialist (; Oliver Neher, Extension Plant Pathologist (; Mireille Chahine, Extension Dairy Specialist (; and Benton Glaze, Extension Beef Specialist (; University of Idaho

Weather conditions prior to, during first cutting, and while making hay have been very moist. Many areas have 2 or more inches of above normal precipitation. Much hay has been rained on or left lying in the field for prolonged time periods due to cool and humid conditions which reduced drying rates. The long drying periods with high humidity allowed field growth of mold on the hay. We will try to state some facts and offer some recommendations for hay producers and livestock producers. 

What is the "black dust" that covers my mower or swather?
The black dust is most likely spores produced by fungal organisms. Spores are how the fungi reproduce and are always present but usually at lower concentration. The black dust on a mower or swather indicates that fungal growth was present prior to cutting.

Combine moisture readings likely inaccurate

The recent and prolonged rain has created problems for Idaho grain producers in eastern and central Idaho, where harvest has been delayed and grain has started to sprout in the head. Grain still standing in the field has been damaged by rain.

Each rain event contributes to additional deterioration of grain quality. While the objective is to harvest as quickly as possible, if the grain is going to be stored for later use as feed (or ethanol, etc), please DO NOT harvest at high moisture content. Already moldy grain will continue moldy growth unless the moisture is below 12%. To arrest growth, harvest below 12% and keep air flowing in the bins.

Moisture sensors in the combine are unlikely to be accurate for sprout damaged grain!

Lost Rivers Grazing Academy Offered in Salmon Idaho September 9-13

September 9-13, Eagle Valley Ranch, Salmon, Idaho
 The Lost Rivers Grazing Academy is a 4-day hands-on workshop for livestock operators and their advisers and consults that want to harvest and sell more of the sun’s energy through grazing of primarily irrigated pastures.
The Academy was first held in 1994 in the Lost River Valley, and has been held at least once annually for the last 12 years.  The program has won state and national awards for Extension programs and is has been recognized internationally.  It has been attended by agency personnel and livestock operators from all over the western US, as well as from eastern US, Canada, Mexico and South America.

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 ( 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

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).
