Mildew Control
All-natural mildew control — Preventative + curative, Non-toxic.
All-natural mildew control from Vegalab Crop Science, powered by Geraniol 17%. Mildew Control targets Powdery mildew — Erysiphales spp. on grapes, apples, cucurbits, brambles, tomatoes, and has been tested on Vines, Apples, Cucumbers, Brambles and Tomatoes.

Geraniol has a two-fold action: it retards spore germination and germ-tube growth, and destroys pathogen cells by inducing K⁺ ion imbalance in the mycelium. Most effective preventatively, but provides curative action on early-stage outbreaks.
