Overview

Field trials show Bacillus velezensis EM-A8 enhances plant growth and biocontrol efficacy against Exserohilum turcicum, suggesting valuable applications in integrated pest management.

Key Points

  • To evaluate the biocontrol potential and growth-promoting effects of Bacillus velezensis EM-A8 in maize.
  • Conducted greenhouse and field trials to assess Bacillus velezensis EM-A8 as a biocontrol agent.
  • Characterized phytohormone production in two formulations using the biocontrol agent.
  • Measured plant biomass and yield enhancements after treatment.
  • Analyzed levels of salicylic acid and phenolic compounds in treated maize tissues.
  • Foliar application increased maize dry biomass by 30%.
  • Both formulations reduced the number of symptomatic leaves affected by NCLB by 25–50%.
  • Yield increases exceeded 1000 kg/ha in treated plants.
