Bacillus subtilis strain IBE 711

Bacillus subtilis strain IBE 711 is a highly effective microbial fungicide used in modern agriculture for plant disease management. It belongs to the class of biological pesticides based on beneficial bacteria, specifically the Bacillus subtilis species, which is well-documented for its suppressive effects on various plant pathogens.

The mode of action of this strain is multifaceted. It primarily utilizes the production of lipopeptides and other antimicrobial metabolites that disrupt the cell membrane integrity of fungal and bacterial pathogens. Furthermore, the bacteria act as strong competitors, occupying the same ecological niches as pathogens, thereby starving them of necessary nutrients and space for growth.

This biological agent is applied across a diverse range of crops, including cereals, greenhouse vegetables, and ornamental plants. It is highly effective in managing root rot, powdery mildew, gray mold, and other common agricultural fungal diseases. It serves as an essential tool for both prophylactic treatment and the early-stage control of outbreaks.

Key agricultural benefits of implementing this biological strain include:

• Significant reduction in chemical residues on harvested produce.
• Enhancement of the plant's natural systemic resistance to stressors.
• Promotion of healthier root development and nutrient uptake.
• Sustainability and compatibility with integrated pest management (IPM) systems.

Proper application requires ensuring adequate coverage of the crop canopy or seed surface. As a live biological organism, its effectiveness is sensitive to extreme UV exposure and desiccation. Therefore, applications are best performed during times of low sunlight, such as early morning or late afternoon. It is recommended to store the product in a cool, ventilated area to maintain the viability of the bacterial spores.
