copper (1) basic copper sulfate Basic Copper Sulfate, Ortho Copper 53 Fungicide, Basi-Cop, Microcop, Tri-Basic Copper Sulfate, Tennessee Copper Sulfate, Spraycop 530, T-B-C-S 53 (2) basic chlorides Coprantol, C-O-C-S, Aceto Copper Chloride, Copper Oxychloride, Kaurital (3) oxides Kuprite, Kocide 101, Cupric Oxide, Copper Oxide, Cuprous Oxide, Brown Copper Oxide, Cuprocide (4) miscellaneous Copper Oleate, GH-41 Copper Resinate, Tri-Cop, For-Cop 80, Copper Carbonate, Zinc Coposil Fungicide (5) liquid, i.e. emulsifiable TC-90, Oxy Cop, Copoloid Citcop 4E, Carmel GH-41 Greenhouse Fogging | These materials, divided into five categories, are substitutes for bordeaux mixture. They control the same range of diseases without leaving an unsightly deposit. Copper fungicides also give control of some bacterial diseases, e.g., fire blight of pome fruits and bacterial blight of lilac and Persian walnut. They are generally much more compatible with other pesticides than bordeaux and often less toxic to tender foliage in cold, damp weather. |
dlazoben Dexon | Soil and turf fungicide that controls Pythium, Phytophthora, and other water molds. Often mixed with PCNB for control of damping-off, seedling blights, and cutting rots. Light-sensitive. |
dlnocap Karathane WD, Miller’s Garden Karaspray | Powdery mildew fungicide and mite suppressant. May “scorch” foliaαe in hot weather. |
dodlne Cyprex 65W Fruit Fungicide | Long-lasting protective fungicide with good eradicant properties. Effective against many fungus leaf spots and blotches, scabs, and anthracnose diseases. |
ethazol Terrazole, Truban, Ko ban | A systemic soil and turf fungicide, usually applied as a drench to control seedling blights, damping-off, and root rots caused by water molds (Pythium, Phytophthora, etc.). Koban is used on turfgrasses. |
ferbam Ferbam, Fermate Ferbam Fungicide, Carbamate, Karbam Black, Ferbam Fungicide | General, safe, protectant fungicide effective against fungus leaf spots and blights, rusts and scabs. Ferbam leaves an unsightly black residue on foliage, flowers and fruit. |
