Phostrogen Organic Fungus Plant Defence 1L sold by Boma Garden Centre

This ready-to-use spray is a natural pretreatment for ornamental plants, applied before disease takes hold to help build resistance against powdery mildew, leaf spot and rust. It works as a physical barrier rather than a conventional chemical fungicide, and is certified for organic gardening use. Suitable for ornamental plants in the garden, greenhouse or conservatory, it comes ready-mixed in a trigger spray bottle so there is no dilution needed before use.
