All the soil pH levels showed significant differences in influencing penetration of juveniles and development of females in the roots. Out of five-selected pH levels, the maximum movement and infection rate of T. semipenetrans was observed at the pH level 8.0 to 8.7 followed by pH levels (7.1-8.0) and (7.70). While at the pH levels (5.0-5.7) and (5.8-6.4) reproduction of T semipenetrans was comparatively less as there were less number of juveniles and ultimately females in the roots.
