WSU Mustard Green Manure Field Day Slated

EPHRATA, Wash. — If nematodes could talk, the last thing you’d hear one say is, “Please pass the mustard.” Rather, nematodes would scream, “Hold the mustard!”

Nematodes are microscopic worms that live in the soil where they present problems for farmers.

Washington State University will hold a field day, Thursday, Oct. 23, to demonstrate how farmers can grow mustard to fumigate their soil and reduce or replace use of broad-spectrum fumigants.

The latest research on the benefits of green mustard manures will be discussed at WSU’s annual green mustard manure field day at the Dale Gies farm located southwest of Moses Lake.

New information will be presented on early planting, control of wind erosion and research results using different mustard varieties.

Two nematologists will present their findings on the effects of mustard varieties on nematode populations. Ekaterini Riga, WSU-Prosser Irrigated Agriculture Research and Extension Center, will talk about screening mustards and similar plants to control nematodes. Russ Ingham, Oregon State University, will discuss combinations of green manures and nematicides, and their potential to replace broad-spectrum fumigants.

Green mustard manures are increasingly proving effective as natural fumigants in potatoes and other crops. It is estimated that more than 20,000 acres in Washington state were planted with mustard green manures last year.

To find the Dale Gies farm, go south from Moses Lake on State Route17 and turn right on Road M. Turn right on Road 5 S.W. and continue west for about 1.5 miles. The Gies farm is on the left. WSU signs will be posted at the intersection of Road M and Road 5, and at the Gies farm.
