Implementing Noxious Weed Control through Multispecies Grazing

Don Nelson, WSU, led a 3-year SARE funded project looking at using sequences of different grazing animals to control noxious weeds, especially useful for non-cropland where other options are not feasible.

The Effects of Reducing Tillage on Pest Management

Andy McGuire, WSU Extension. 2007. An increasing number of farmers in the Columbia Basin are adapting reduced tillage systems from other regions to our conditions and crops. This paper will examine the general effects of reducing tillage on the management of weeds, insects, and diseases. Because these systems have been developed mainly in the Midwest and Canada, much of the information presented here is for the conditions and crops (mainly corn and wheat) in those regions. Experience will show what holds true under our conditions.

The Myth of Compost Tea, Episode III: Aerobically-brewed compost tea suppresses disease

Chalker-Scott, L. 2006. WSU Puyallup Research and Extension Center. This column is the latest follow-up to the 2001 Fact Sheet and 2003 review on the effects of aerated compost (ACT) on disease suppression. The article included unpublished results from university researchers from Cornell, Penn State, Rutgers and Michigan State Universities.

Organic Control of Cherry Fruit Fly

The active ingredient spinosad, a microbial insecticide, was tested for efficacy against cherry fruit fly. Several formulations were tested. The GF-120 product, a combination of spinosyn and a feeding attractant, proved very effective. A new system of control using point sources versus complete canopy cover was developed. The use of GF-120, an organically approved material, for cherry fruit fly control has become widespread among cherry producers in the region, both conventional and organic. It is very effective, non-toxic to humans, low impact to beneficials, and low cost due to the low volume used and quick application.

Peshastin Creek Areawide Organic Project

The Peshastin Creek Project was created as a joint effort between the Peshastin Creek Growers Association and the Pear Entomology Lab of the WSU Tree Fruit Research and Extension Center in Wenatchee. The research lab provides a monitoring service for the growers in the valley, to support their efforts toward increased use of environmentally-friendly pest management. Bluebird Fruit has created a special “Gently Grown” label for the fruit produced by the PCG Association. The project compares insect pest management under conventional, ‘soft’, and organic management regimes.

Healing the Land through Multi-Species Grazing

A noxious weed invasion is underway on the rangelands of the western United States that is causing significant problems in the form of ecosystem and bio-diversity damage resulting in a reduction in the carrying capacity of grazing animals. The expenditure of millions of dollars on control measures has not been successful; these measures have had negative impacts on livestock producers’ profitability and, in some cases, have caused environmental problems. This DVD is about the use of multi-species grazing (cattle, sheep, goats) as a tool in an integrated approach to the control of noxious weeds. It depicts the activities of a 2-year regional project funded by the USDA Sustainable Agriculture Research and Education Professional Development program. Thirty participants from four states (Washington, Idaho, Oregon, and California) took part in this project. They represented state/federal agencies, extension, county weed boards and ranchers. Three of these projects are described in this DVD. 37 minutes. (available for purchase or free online viewing)
