Other claims from this paper (10)
- Intervention effect Immersion of Meloidogyne graminicola larvae for 48 h in 100% Paecilomyces lilacinus culture filtrate caused 100% larval mortality, versus 7.12% and 18.72% after 6 and 12 h.
- Intervention effect Culture filtrate at 100% concentration produced no galls on rice seedlings.
- Intervention effect Culture filtrate limited egg hatching of the nematode, shown by fewer galls on rice seedling roots.
- Intervention effect Mycelial extract was more potent than culture filtrate extract against M. graminicola larvae and eggs.
- Observation Fraction 3 caused 39% nematode mortality in the bioassay.
- Observation The nematoxic compounds are suggested to be present in fraction 3 and fractions 5, 6 and 7.
- Observation GC-MS of the active fraction showed more than 20 compounds, with 5 major ones.
- Observation The main compound of the active fraction was partially identified as an azulene derivative with two unsaturation points.
- Observation Dried ethyl acetate fraction gave 76.91% mortality at 400 mg/ml.
- Observation A lethal concentration (LC50) was reached at 300 mg/ml.
