Barcham Sentinel

Sentinel is a unique blend of liquid silicon and plant extracts that naturally strengthens plant cells and increases the size and number of plant hairs, providing added protection to tree and plant cuticles.

Its use reduces susceptibility to insect feeding and disease infection. Regular use will support the healthy growth of all plant species.

Supplied in a 10ml vial, with measuring pipette and empty trigger spray bottle.

Only 0.5ml of Sentinel must be mixed with 500ml of water in the trigger spray bottle.

10ml is, therefore, enough to produce 20 full trigger spray bottles for application.
