Key Findings
- The study by NSTRI explored using Trichoderma spp. and Bacillus spp., including their gamma radiation-induced mutants, to control root-knot nematodes in tomato plants
- Bacillus spp. were effective in lab tests, reducing nematode egg hatching by 16-45% and killing 30-46% of juvenile nematodes
- Greenhouse trials showed that mutant isolates combined with chitosan reduced nematode reproduction by 94%, significantly lowering plant damage
