Figures & Tables

Figure 1

Relationship between the paralyses of M. incognita and R. reniformis treated for 24 hr and 48 hr with water solutions of tioxazafen. Equations were derived by nonlinear regression of probit analysis. For each equation, the R2 value was 0.99 (P = 0.0001).

Figure 2

Effect of tioxazafen on hatch of M. incognita and R. reniformis. Different letters over bars per sample day indicate a significant difference at α = 0.05 according to Fisher’s LSD procedure. LSD, least significant difference.

Figure 3

Recovery of M. incognita and R. reniformis treated with tioxazafen. Each species was treated with water solutions corresponding to its 48-hr EC50 value of tioxazafen for 24 hr, and then rinsed and transferred to distilled water. Different letters over bars indicate a significant difference at α = 0.05 according to Fisher’s LSD procedure. LSD, least significant difference.

Figure 4

Effect of low concentrations of tioxazafen on infectivity of M. incognita and R. reniformis on tomato roots. Different letters over bars indicate a significant difference at α = 0.05 according to Fisher’s LSD procedure. LSD, least significant difference.
