Reliant Fungicide Mode of Action
RELIANT is a systemic fungicide which has both xylem and phloem mobility, in that it will move systemic throughout all parts of plants. It will move from plant roots into the newly emerging shoots and conversely from new shoots into the root system.
RELIANT is absorbed by all plant tissue regardless of where it is applied and is directly fungistatic, in that it slows the growth of the disease pathogen and inhibits the formation of new spores by the pathogen.
When absorbed by the plant RELIANT directly effects plant metabolism by stimulating the production of ATP and ADP along with the defensive response of accumulation of phytoalexins (immune bodies) similar to that in humans. These phytoalexins enhance the activity of the plant's dynamic defense system, causing rapid changes within the cells of lytic enzymes, thickening of cell walls, higher cell pressure and lignification to occur within the cell.
This increase in "plant robustness" is sometimes called "Systemic Acquired Resistance" and can directly off set the onset of pathogen attack. Below is an unprotected cell under pathogen attack.
This very complex mode of action can be simplified into making the plant more “robust healthy, ready to withstand pathogen attack” and environmental stress.
How does PENTRA-BARK work?
All woody plants have microscopic openings in the exterior protective bark periderm layer called lenticels. These lenticels are functionally used for plant transpiration and pressure regulation.
Lenticels connect directly to the plant’s annual spiral openings or vascular metabolic transport system contained in the plant’s cambial phelloderm.
When PENTRA-BARK is applied to the woody bark periderm in combination with systemic pesticides it opens the lenticels and enables movement through the lenticels into the plant’s vascular transport system.
