Bacillus amyloliquefaciens strain AT-332

Bacillus amyloliquefaciens strain AT-332 is a biological active ingredient primarily used as a powerful biofungicide in integrated pest management (IPM) systems. As a rhizosphere-competent bacterium, it effectively establishes a protective barrier around the root system, preventing the colonization of soil-borne plant pathogens.

The mode of action for this strain involves the production of bioactive lipopeptides, such as surfactins and bacillomycins. These compounds disrupt the integrity of the fungal cell membranes, causing the inhibition of spore germination and mycelial growth. Furthermore, the bacterium actively promotes systemic acquired resistance (SAR) within the host plant, bolstering its natural defense mechanisms.

It is commonly utilized against a wide array of fungal and bacterial infections, including damping-off, various wilts, and powdery mildew. Crops benefiting from its application range from cereals and vegetables to greenhouse ornamentals. Its ability to thrive in diverse soil conditions makes it a versatile tool for farmers looking to enhance yield quality.

Application instructions emphasize the importance of timing and environmental conditions. The efficacy of AT-332 is highest when applied during periods of sufficient moisture, which allows the bacterial colony to establish quickly. It is recommended to apply the product during the early stages of plant development to ensure full protection throughout the growing season.

When handling the product, standard safety precautions should be observed, although the strain is considered non-toxic to mammals and beneficial insects. Users should ensure storage in cool, dry places to maintain the viability of the microbial spores.
