Observation Fusarium crown and root rot incidence was consistently high in nontreated tomato plots (80 to 100%).
Observation Disease severity of Fusarium crown and root rot varied by site.
Association Tomato yields were reduced by 10 to 57% at high disease severity sites compared with sites treated with MBC.
Intervention effect Application of MBC reduced FCRR incidence in all experiments compared with nontreated plots.
Intervention effect Chemigation with metam sodium at 701 or 935 liters/ha failed to reduce the disease in tomato.
Intervention effect Soil injection of metam sodium at 935 liters/ha failed to reduce the disease in tomato.
Intervention effect Rotovation of metam sodium at the same rate into preformed beds consistently reduced FCRR incidence, equivalent to MBC.
