October 1, 2020 – As part of its mission to provide organic farmers with sound, science-based information on weed and pest management strategies, OFRF has awarded grants to farmer/researcher collaborations at the Georgia Organic Peanut Association and the University of Idaho.
The first grant was awarded to Donn Cooper, an agricultural outreach and education specialist at Cooper Agricultural Services working in collaboration with the Georgia Organic Peanut Association. Cooper and his team will examine the effectiveness of an integrated weed control system in organic peanut production utilizing regular mechanical cultivation and Eugenol, a broad-spectrum herbicide derived from cloves and approved for certified organic production in the commercial formulation known as Weed Slayer. The project will be conducted with four certified organic farmers in Southwest Georgia.
While Georgia is the largest peanut-growing state, producing approximately three billion pounds annually, certified organic production has been impeded by the lack of a comprehensive approach to controlling weeds as well as certified organic processing facilities. The goal of the project is to address the first challenge by creating a weed management system specific to certified organic peanut production that can be replicated by farmers—fostering the expansion of certified organic peanut acres in the Southeast, while developing a value-added revenue stream for new, beginning, and socially disadvantaged producers operating small farms.
The second grant was awarded to Professor Arash Rashed, leader of the Idaho IPM Laboratory at the University of Idaho, to evaluate the efficacy of two biological control agents of wireworms—entomopathogenic nematodes and fungi—in organic production. The research team aims to identify the most effective entomopathogenic treatment against wireworms and successfully establish the biocontrol agent in organic farm soil.
Managing wireworms is a challenge facing organic producers in the Pacific Northwest due to their long-life cycle, subterranean living habitat, and ability to use a wide range of host plants. Although there are a few insecticides available for conventional farming, there is no effective control measure against wireworms in organic production. Focusing on one of the most damaging species in the Pacific Northwest, the sugar beet wireworm, this project will evaluate and compare the efficacy of entomopathogenic nematode and fungi treatments against wireworms in organic vegetable production. Three certified organic farmers are participating in the project. Findings will be communicated through field days and workshops.
These grants are two of 13 OFRF is awarding this year to help address the top challenges facing organic farmers and ranchers. As a result of OFRF’s research, education, and outreach efforts, thousands of farmers have received pertinent research and training information. Results from all OFRF-funded projects are available to access for free at ofrf.org.
