Fig. 7. Soil dehydrogenase activity in Watsonville and Oxnard soils 1 wk after fumigation with MeBr or an alternative (Week 1), at planting (Week 4), and at peak strawberry growth (37 or 30 wk). For each sampling date, means followed by a different letter are significantly different at P < 0.05. Absence of letters indicates no significant differences. Error bars represent the standard deviation, n = 4. CP chloropicrin; EC, emulsifiable concentrate; PrBr, propargyl bromide.
