Interpretive Summary:

Technical Abstract: Anaerobic soil disinfestation (ASD) has been shown to be effective in reducing Verticillium dahliae in soil and to be able to provide marketable fruit yields compatible to fumigation in California strawberry systems. However the effect of ASD on charcoal rot caused by Macrophomina phaseolina in California strawberry has not been documented. We tested ASD, ASD + mustard seed meal (MSM) and MSM in a large scale field demonstration in an organic field in Oxnard CA, that has M. phaseolina present in the soil. A doubling of yields relative to the grower standard, and a reduction in the incidence of disease caused by M. phaseolina, was achieved by using ASD-RB 9 t/ac at this organic site. MSM 2t/ac failed to control M. phaseolina and resulted in yields that were more than 20% below the ASD-RB9 yields, although still substantially higher than the grower standard.
