Biological control of plant pathogens in raspberries using beneficial microorganisms, compost teas and nutritional management

From September of 1994 through June of 1995, with the financial assistance of OFRF, Organic Ag Advisors and Aptos Berry Farms conducted research on the biological, nutritional and cultural control of Botrytis and Powdery Mildew an Raspberries at the Aptos Berry Farm on Thompson Road in Watsonville CA The research took place in a raspberry operation that uses an integrated organic and conventional farming system, on a raspberry variety chosen because of it's history of trouble with these plant and fruit pathogens, These raspberries bear fruit in fall and spring, thus giving the opportunity

Investigating the Impact of Green Manures and Weed Mat on Soil Biota and Tree Growth in Organic Peach Tree Orchards

In the spring of 2001, organic peach blocks were established at two Western Colorado Research Center sites: Rogers Mesa and Orchard Mesa. These plantings were established to allow multi-disciplinary research, systems comparisons, and demonstration of an organic production system for peaches. The objective of this project is to study the effects of different organic management practices on the soil microbial and faunal communities within peach orchards on the western slope of Colorado.

Nebraska organically grown grapes

Grape production in the Midwest is increasing at a rapid rate. Very little if any are being grown organically due to the fact that little is known about organic disease control on grape in the Midwest. Sulfur is a good material to use for control of most of the major diseases but sulfur treatments will injure some cultivars of grapes. Many cold hardy grape cultivars have never been tested for sulfur sensitivity. The object of the project is to determine which varieties of grapes are tolerant to sulfur applications.

Alternative Methods of Raspberry Production and Root Rot Control

Root rot (Phytopthora fragriae var. rubi) is of primary concern to all raspberry growers in Washington, and is of particular concern to organic growers who have fewer options for disease control. This trial is focused on organic root rot control, however all raspberry growers will benefit from new disease management strategies.

Deploying microbes as a seed treatment for protection against soil-borne plant pathogens

Plant diseases, especially those caused by soil-borne seed infecting pathogens, pose a serious threat to the production of both greenhouse and field crops. Conventional farming operations often use fumigants and chemical seed treatments, which can be harmful to human health and the environment, for controlling seed and seedling pathogens.

Farm Made: A Guide to On-Farm Processing for Organic Producers

There are two obvious barriers organic producers face when they consider on-farm processing. The first is psychological. On-farm processing can appear intimidating and beyond reach, on one hand; on the other, it may seem unnecessary to someone who is already “adding value” by raising crops or livestock organically. The second barrier—a more pragmatic one—is the lack of good, producer-friendly information on small-scale organic processing and handling.

Breeding day-neutral strawberry cultivars for organic production in the Pacific Northwest

This award continues OFRF support for a breeding effort to develop strawberry varieties that produce fruit over a 4-5 month period in the Pacific Northwest. In contrast, June-bearing strawberries only produce fruit for about one month.
