Bacillus amyloliquefaciens strain D747
Description
Mode of action
Bacillus amyloliquefaciens strain D747 is a highly effective naturally occurring bacterium used as a biological fungicide for broad-spectrum disease management.
The strain produces bioactive lipopeptides that act as natural antibiotics, effectively inhibiting the growth and spore germination of various plant pathogens.
By rapidly colonizing the plant's surface and root system, this strain outcompetes harmful fungi for space and essential nutrients, creating a biological barrier.
In addition to its antifungal properties, D747 triggers systemic acquired resistance (SAR) in plants, strengthening their internal defense mechanisms.
The consistent use of this strain promotes a healthier rhizosphere environment, contributing to overall plant vigor and long-term crop protection.
What it targets
This strain is widely used to manage diseases such as powdery mildew, grey mold, and various leaf spot pathogens affecting high-value horticultural crops.
It is specifically effective against pathogens that develop resistance to chemical fungicides, making it a crucial component in Integrated Pest Management (IPM).
Rates and timing
The application timing should be proactive, targeting the early stages of plant development to establish a colony of beneficial bacteria before pathogen pressure peaks.
Application is performed through foliar spraying, ensuring that the crop canopy is thoroughly covered to maximize the protective biological footprint.
Frequency of application varies based on environmental conditions, as high humidity and moderate temperatures significantly favor the activity of the strain.
Restrictions
Avoid mixing D747-based products with strong bactericides or high-pH chemicals that could drastically reduce the viability of the beneficial bacteria.
Ensure that the water used for spray preparation is free from chlorine or other disinfectants, as these chemicals can harm the biological agent.
