2013 Idaho Grasshopper and Mormon Cricket Program

Grasshoppers and Mormon crickets are one of the most serious pest problem on Idaho rangeland and adjacent cropland.  These are high priority programs for the Idaho Department of Agriculture and the cooperating agencies.  The Idaho program manager, Dick Lawson reired in January and have been replace by Dan Safford.

In the past the program has included a combination of coordinated insecticide treatments, as well as the distribution of carbaryl bait to landowners.  Due to problems with the NPDES permitting, cooperative cost-share spray programs will NOT be conducted in 2013.

Carbaryl bait will be available to landowner who take full responsibility for the labor of application and proper application and storage.  No bait will be available for agricultural lands of less than 5 acres or agricultural land of 5 acres or more that does not produce an agricultural income.  A request for evaluation form must be completed and approved before the bait will be issued

For complete information and a copy of the necessary forms and contact information, please click the cricket below!

Southeast Idaho Cereal Pest Alert for Barley Yellow Dwarf

PNW Pest Alert. Prepared by Juliet M. Marshall, May 9, 2013.
Widespread incidence of Barley Yellow Dwarf Virus (BYDV) – infected winter wheat and winter barley is evident throughout the Magic Valley from Buhl to Murtaugh. Symptoms include yellowing of leaves, stunting of plants both above and below ground (look for small root systems), and irregular heading with small heads in affected plants. Often, the most severe symptoms will occur along field edges and the edges created along the tracks of pivot tires. (Please see pictures.) There may also be a yellowing to a very characteristic reddening of leaves of infected weedy grasses in nearby ditch banks (Fig. 3), which also host the virus and aphids. Additional symptoms may also include notching of the leaf margins, twisting, leaf tip scorch, and abnormal development of emerging leaves.
