(Pseudomonas fluorescens A506)
(Pseudomonas fluorescens A506)
Mode of action: Pseudomonas fluorescens A506 is a natural occurring ice nucleation negative bacterium that competes with ice nucleation positive (ice crystal forming) bacteria when applied to plants. Pseudomonas fluorescens A506 also produces a glycoprotein that acts as an anti-freeze substance. The anti-freeze protein binds with small ice crystals and prevents it from growing. The bacteria colonize the leaf surface and also penetrate through stomata to release the anti-freeze intercellular. This action will prevent or mitigate damage due to ice nucleation formation.

Background: Cold and frost damage to plants is the result of ice crystal formation damaging the cytoplasm membranes and cell walls of leaves, flowers, and fruit. The cytoplasm leaks out, cells die off and fruit loses moisture. The cytoplasm of frost-hardy plants can supercool with the result that ice crystals do not form that readily. Frost-sensitive plants can normally not supercool lower than -2 to -5 ⁰C.

Application: Frostbite has to be applied timeously, several days before frost is expected. This is in order for the bacteria to establish and start producing the anti-freeze protein. It should be applied with the onset of flowers and directly after flowering. Protection is normally rendered up to -3 ⁰C outside temperature. This product is not effective against black frost.
