Other claims from this paper (12)
- Observation Beauveria bassiana B094 was pathogenic to Spodoptera exigua larvae, causing 99.8% mortality in laboratory screening.
- Observation The LC50 of B094 for 3rd-instar Spodoptera exigua larvae was 4.8 × 10 5 spores/mL.
- Observation B094 established endophytic colonization of sweet corn varieties Zhetian 19 and Zaotiannuo 211 after seed inoculation.
- Observation Endophytic colonization of sweet corn by B094 peaked at 7 days after emergence.
- Association B094 colonization frequency and density were markedly higher in leaves than in stems of sweet corn.
- Observation B094 colonization of sweet corn leaves declined to 24.3% by 28 days after emergence.
- Observation Leaves from B094-colonized sweet corn plants at 14–21 days after emergence disrupted development of Spodoptera exigua larvae.
- Intervention effect Inoculated sweet corn plants had less foliar damage than controls in greenhouse and field trials.
- Observation Colonization patterns and biocontrol effects of B094 were similar across sweet corn varieties.
- Association B094 colonization increased bacterial genera associated with plant growth promotion or biocontrol in the sweet corn rhizosphere by 22.5% and 81.6%.
- Association B094 colonization decreased fungal genera commonly reported as plant pathogens in the sweet corn rhizosphere by 87.7% and 78.1%.
- Recommendation Seed treatment with B094 is recommended as an environmentally friendly strategy for sustainable pest management in sweet corn.
