Fungicides can be "contact", "translaminar" or "systemic". Contact fungicides only protect the area where the fungicide spray is deposited. Translaminar are fungicides that redistribute the "chemicals" from the upper side of the sprayed leaf to the lower side of the same leaf. Systemic are fungicides that are taken up and redistributed by the plants to all parts, upper and lower, of the plants and remain active and protects the plant for a short period of time. That's how I understand it.


Bacillus subtillis strain QST-713
Fungi used as "Biocontrol"agent against Botrytis & Anthracnose
Benzalkonium chloride
Complex compound
Many applications from disinfectant (in Dettol & Lysol brands) to control algae in swimming pools (alginox, etc) or bacteria. Useful to "sanitize" your greenhouse.
Mancozeb, Propamocarb hydrochloride.
Propamocarb is a useful systemic fungicide against rot, botrytis, etc,
Cinnamomum verum
Organic Compound
Copper(I) Oxide; Copper(II) Hydroxide; Copper(II) Sulfate; Copper Oxychloride;
Outstanding Fungicides. The roots must be protected because copper can damage roots.
Synthetic pyrethroid.
Other chemicals are better.
Jojob Oil
Fungicide. Used to control mildew.
Systemic fungicide. It is a steroid demethylation inhibitor. Inhibits ergosterol biosynthesis. Ergosterol = Critical component of fungal cell membranes. Has a relatively low acute toxicity.
Pyrethroid family
Synthetic chemical that functions as a neurotoxin. Controversial. Orchid growers: There are better products on the market.
Systemic fungicide. Not to be confused with Phosphoric Acid found in fertilisers.
Fungus acting as natural fungicide.
Ulocladium oudemansii
Fungi used as "Biocontrol" agent against Botrytis
