Abstract

To use unique nematicidal mechanism of Stropharia, the strain 1.2052 was evaluated for its potential to control the root-knot nematode Meloidogyne incognita on tomato. In vitro, the inhibition rate in 24 h of Stropharia sp. 1.2052 isolate was 100% for second-stage juveniles of M. incognita and Panagrellus redivivus, 41.81% for Caenorhabiditis elegans and 99.25% for Bursaphelenchus xylophilus, respectively. In pot experiments, isolate 1.2052 reduced the root-knots to 68.16 to 84.19% in one month and 45.28 to 88.24% in two months after treatment, respectively. The reduction of nematodes in soil ranged from 26.39 to 61.18% compared to the negative control. There were significant efficacies for control of root knot nematodes on tomato.

 

Key words: Stropharia, Meloidogyne incognita, biological control, root-knot nematodes.
