Fig. 4. Number of infective juveniles (IJ) (250 ml soil)−1 at the treatment dose of 40 × 103 and 60 × 103 IJ pot−1 10, 20 and 30 days after treatment. A: S-PQ16 strain, B: H-KT3987 strain. Letters indicate significant differences among interval times in each (lower case andupper case) IJdose (one-way ANOVA, P <0.05).
