Progress Report Objectives (from AD-416) Investigate cultural practices as non-chemical alternatives to methyl bromide in perennial strawberry production systems. Approach (from AD-416) Crop rotation, composts, and biological control agents will be compared to methyl bromide fumigation for control of strawberry black root rot in commercial strawberry plantings. Replicated plots with each of these treatments have been established at two grower cooperator farms, and data will be collected to evaluate disease incidence and severity, and plant vigor and productivity. Significant Activities that Support Special Target Populations This report serves to document research conducted under a Reimbursable agreement between ARS and Michigan State University. Additional details of the research can be found in the report on the parent project 1275- 21220-213-00D entitled �Enhancement of Small Fruit Germplasm through Genomic Characterization and Genetic Improvement with Emphasis on Disease Resistance�. A strawberry planting to test horticultural practices for the control of black root rot disease of strawberry was established and maintained on a grower�s farm. Data were collected spring and summer 2007. Progress was monitored by the ADODR through phone calls, and e-mails and visits to the grower�s farm.

Progress Report 4d Progress report. This report serves to document research conducted under a Reimbursable Agreement between ARS and Michigan State University, subcontracted under a grant from the CSREES Methyl Bromide Transition program. Additional details of the research can be found in the report for the parent project 1275-21000-175-00D, Small Fruit Crops in Sustainable Production Systems. Field studies were initiated in 2005 at a grower-cooperator site in Frederick County, Maryland. Treatments were established to compare cultivars and cultural practices for alleviating the replant disorder strawberry black root rot (BRR). In 2005, field plots were established with a rotational crop or were planted directly to strawberry. In 2006, all plots were cultivated and half of the strawberry-planted plots were fumigated with methyl bromide. Half of each plot was then planted with the variety Allstar (tolerant to black root rot) and the other half to Cavendish (susceptible
to black root rot). In 2007, differences between cultivars and between fumigated, non-fumigated, and rotational treatments will be evaluated.
