Figure 3. Effect of phosphite treatment and P. plurivora infection on plant mortality over time.

Treatments: Con (black square): not phosphite treated and not inoculated control plants; Phi (green square): plants sprayed with phosphite (0.5%) on leaves until run off; Plu (red circle): roots infected with P. plurivora; Phi-Plu (blue triangle): plants sprayed with phosphite (0.5%) on leaves until run off four days prior to infection with P. plurivora. n = 6 plants per treatment. The experiment was repeated three times showing similar results. dpi: days post inoculation.
