OMRI-LISTED FUNGICIDES THAT GEORGIA FARMERS USE
PRODUCT NAME
Actinovate
Cease
Serenade ASO
USE
Powdery Mildew, Downy Mildew, Botrytis, Alternaria, and other aerial borne pathogens; Also root decay diseases
Powdery mildew, Botrytis (gray mold), Anthracnose, Alternaria leaf spots, Downy mildew (suppression), Bacterial leaf spots and blights
Powdery mildew, Anthracnose, Botrytis (gray mold), Early blight, Septoria leaf spot, Downy mildew, Bacterial spot and speck, Xanthomonas, Fire blight
WHERE TO FIND
NOTES
high concentration of a patented beneficial bacterium in a 100% water soluble powder
Can be applied as a foliar spray or a soil drench; most effective as a preventive treatment; similar to Serenade ASO
Cueva Fungicide Concentrate
Powdery mildew, Downy mildew, Early and late blight, Septoria leaf spot, Anthracnose, Botrytis/gray mold, Fire blight, Peach leaf curl, Scab, Bacterial spot and speck, Rust diseases
Active ingredient: Copper Octanoate (Copper Soap); Must be used in a manner that minimizes copper accumulation in the soil and shall not be used as herbicides
Double Nickel 55
Broad spectrum biofungicide
Naturally-occurring rhizobacterium; most effective as a preventative, with the bacteria colonizing roots, leaves, and other plant surfaces preventing the establishment of disease-causing fungi and bacteria
Howler
Effective on a wide range of soil-borne and foliar diseases
Produces antibiotics that directly attack pathogens; produces enzymes that break down the cell walls of fungi and prevent attachment of spores to leaves; induces plant resistance to inhibit fungal growth; can be used effectively at every phase of production
Oxidate 2.0
Blights, rusts, rots, spots, mildews, scabs, and more
Active ingredients: hydrogen peroxide and peroxyacetic acid; contact oxidizer: kills pathogens on contact rather than moving systemically through the plant; works best as a preventative or early knockdown tool
Regalia
Powdery mildew, Downy mildew, Botrytis/gray mold, Early and late blight, Alternaria leaf spot, Anthracnose, Bacterial spot, Fire blight, Rust diseases
Performs better as a suppressive, resistance-building tool than as a “knockdown” fungicide during an active outbreak
Rootshield
Preventative control of major root diseases
Apply before roots have fully emerged/developed; Do NOT apply to sugarcane, pechay (bok choi), rice, mushrooms, kiwi, tobacco, barley, oats, lemon, apple, and chickpea. Not for use on aquatic crops.
Designed to be applied preventatively; non-toxic to beneficial insects and can be applied up to and including the day of harvest
Surround
Protects against pests, disease, and heat stress/sunburn
Made from calcined kaolin clay, creates a thin, white “particle film” coating on leaves, stems, and fruit; best to apply when bees are not actively foraging
Trilogy
Powdery mildew, Botrytis, Leaf spots, and other fungal diseases
Active ingredient: Neem oil; works through coating fungal spores and preventing disease development
