Stripe Rust Spotted Near Hazelton May 22nd

I have had the first report of stripe rust in Idaho this year in the Hazleton area on Brundage soft white winter wheat. It was first seen 22 May by the pilot for Red Baron, Clay Seamons, and reported to me by Jared Hobson. Clay sent pictures and yes it is stripe rust. 

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

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.

User-Friendly Program Updates Phosphorus Management

A more comprehensive and consistent system for modeling phosphorus loss is now available, thanks to work by ARS scientists whose user-friendly spreadsheet program can predict field-scale phosphorus loss in runoff for a whole year, and can also be used in many different states to quantify field-scale phosphorus loss and soil phosphorus changes over 10 years for a given set of runoff, erosion, and management conditions.  

 

A more comprehensive synopsis of the program and links to the research, magazine article and the free computer program are available HERE!

Cereal Disease Forcast for East Idaho for 2013

It will be difficult to forecast disease for the upcoming year, as everything depends on mother nature and the production practices of each grower. I have no control of either! However, I can give an opinion of what I expect to see in wheat and barley.

Evaluating Alfalfa Stands In the Spring

Dr. Dan Understander, extension forage specialist at the University of Wisconsin has done a lot of work on early season evaluation of alfalfa stands for winter kill and disease.  He has found that stands with less that 50 stems per square foot can be expected to have reduced yields.  While Understand and other have listed 6 plants per square foot as necessary for maximum yield but the stem count seems to work out better, integrating the health of the plants.  Glenn Shewmaker, University of Idaho extension forage specialist, feels that one might go down to 3 plants per square foot with slight yield reduction.

Dr. Understand has a video on evaluating plant health at http://youtu.be/hoJUU1rmCko.    He also has associated Extension Publications, Alfalfa Stand Assessment : Is it good enough to keep at:

eXtension Entrepreneurship Webinar Series Begins April 11th with Farmers Market

Mark your calendars! The eXtension Entrepreneurship webinar series is finishing the season with three presentations of interest to farmers' market vendors and  farmstand owners. All webinars will air monthly on the second Thursday at 2:00pm (ET); 1:00pm (CT); 12:00pm (MT); 11:00am (PT) at https://connect.extension.iastate.edu/etc-cop.

On Thursday April 11, 2013 join Londa Nwadike, University of Vermont Extension Food Safety Specialist, for Food Safety for Farmers Market Vendors. Farmers Markets are a great venue for food producers and value-added processors to introduce their products to consumers, make sales, and also to get valuable feedback on their products. To protect this valuable outlet for your food products, it is essential that all the food sold at the market is as safe as possible and follows local, state and federal regulations. This helps to assure your customers that your business, as well as the entire Farmers Market, has product safety and quality in mind. This webinar will provide information on the food safety risks associated with direct marketing of foods, the regulations that farmers market vendors are required to follow, and strategies/best practices for maintaining a safe environment at farmers markets.
