This study showed that C. rosea strain PHP1701 can be used to control M. incognita under greenhouse conditions.Finally, we recommend the use of C. rosea strain PHP1701 for short-season crops and to reduce M. incognita populations without a host crop,such as on fallow land before planting the next crop in an integrated pest management program.Overall, C. rosea strain PHP1701 is a promising new biocontrol agent.
