e1“Treatment with the fermentation supernatant of GC-7 in vitro showed a highly lethal effect on second-stage juveniles of Meloidogyne graminicola , with the mortality rate increasing to 95.82% at 24 h and egg hatching significantly inhibited, with a hatch inhibition rate of 60.65% at 96 h”
e4“The bacterium significantly reduced the level of damage caused by M. graminicola infestations to rice ( Oryza sativa ) in greenhouse and field experiments”

Other claims from this paper (9)
- Intervention effect GC-7 fermentation supernatant significantly inhibited egg hatching of M. graminicola in vitro, with a hatch inhibition rate of 60.65% at 96 h.
- Intervention effect GC-7 culture reduced the gall index and nematode population in rice roots and soils under greenhouse conditions, compared with the control.
- Intervention effect GC-7 culture inhibited nematode development under greenhouse conditions, compared with the control.
- Intervention effect Application of GC-7 in the field showed a high biocontrol efficacy against M. graminicola, with a control efficiency of 58.85%.
- Intervention effect Application of GC-7 in the field promoted plant growth of rice.
- Intervention effect Inoculation of GC-7 significantly suppressed final nematode populations in soil of M. graminicola-infested rice fields under natural conditions.
- Intervention effect GC-7 treatment remarkably increased defense-related enzyme activities in rice roots compared with roots challenged by M. graminicola.
- Intervention effect Inoculation with GC-7 significantly enhanced the expression of defense genes (PR1a, WRKY45, JaMYB, AOS2, ERF1, ACS1) related to salicylic acid, jasmonic acid and ethylene signaling in rice roots.
- Recommendation GC-7 could be an effective biological component in the integrated management of M. graminicola infecting rice.
