[Ecological effects of multifunctional micro-flora agent in environment]

Area of Science:

• Agricultural Microbiology
• Plant Pathology
• Environmental Science

Context:

• Fusarium oxysporum f. sp. cucumerinum causes significant damage to cucumber crops.
• Developing sustainable agricultural practices is crucial for disease management and yield improvement.
• Microbial agents offer an eco-friendly alternative to synthetic pesticides.

Purpose:

• To screen and evaluate beneficial microbial strains from cucumber rhizosphere for agricultural applications.
• To investigate the feasibility of a multifunctional microbial agent combining plant growth promotion, disease suppression, and pesticide degradation.
• To assess the compatibility and efficacy of Brevibacillus brevis (ZJY-1) and Bacillus subtilis (ZJY-116) with a chlorpyrifos-degrading strain (DSP3).

Summary:

• Screened Brevibacillus brevis (ZJY-1) and Bacillus subtilis (ZJY-116) for their ability to inhibit Fusarium oxysporum f. sp. cucumerinum and promote cucumber growth.
• Tested the efficacy of these strains, individually and in combination with Alcaligenes faecali (DSP3), a chlorpyrifos-degrading bacterium.
• Results confirmed that ZJY-1 and ZJY-116 retained their beneficial functions when co-applied with DSP3, and DSP3's degradation activity was unaffected.

Impact:

• Demonstrates the potential of multifunctional microbial agents for integrated crop management.
• Provides a foundation for developing sustainable, eco-friendly solutions in agriculture.
• Highlights the successful co-application of beneficial microbes without compromising their individual functions or environmental benefits.
