Sentinel is a unique blend of liquid silicon and plant extracts which naturally strengthens plant cells and increases plant hair number/size to armour tree and plant cuticles.
Its use reduces susceptibility to insect feeding and disease infection. Regular use will support the heathy growth of all plant species.
Supplied in a 10ml vial, with measuring pippette and empty trigger spray bottle.
Only 0.5ml of Sentinel is required to be mixed with 500ml of water in the trigger spray bottle.
10ml is therefore enough to produce 20 full trigger spray bottles for application.
