The label is the law. Read your product's label before you mix or apply; the rates here come from the labels listed under Sources.
- Active ingredient
- Propiconazole (CAS 60207-90-1)
- Chemical class
- Triazole; FRAC Group 3 demethylation inhibitors (DMI) of sterol biosynthesis.[2]
- Mode of action
- FRAC Group 3: DMI fungicides: C14-demethylase inhibitors in sterol biosynthesis[2]
- Signal words
- Banner MAXX II Fungicide: Caution[1]
PPZ 1.55 Fungicide (residential concentrate; also packaged ready-to-spray): Caution[3]
Landscape and ornamental use
On ornamentals and landscape plants, it's mixed at 2 to 24 fl oz per 100 gallons of water depending on the disease; for general disease control in landscapes, 6 to 8 fl oz per 100 gallons every 21 days. It isn't for tree injection or irrigation systems.[1]
Resistance
FRAC Group 3 DMIs carry a resistance risk, so rotate or tank-mix with fungicides from other groups; the label pairs it with contact fungicides for brown patch.[2][1]
Where it is used
Identify the disease first; the label says diagnostic kits or other identification are essential to choosing the right control.[1]
Apply after mowing, or let the spray dry completely before mowing. For leaf diseases, let it dry before irrigating; for soil-borne diseases it can be watered in.[1]
Bermudagrass can be sensitive: don't exceed 4 fl oz per 1,000 sq ft every 30 days on any bermudagrass variety.[1]
Use higher rates and shorter intervals under heavy disease pressure, and pair it with turf practices that keep grass healthy.[1]

How to apply it, step by step
1. Protective gear
- This is a CAUTION-signal product that is harmful if swallowed. The label names no protective gear, but wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, using tobacco or using the toilet.[3]
- Never spray it so that it lands on people or pets, directly or as drift.[3]
2. Before you spray
- It prevents disease better than it cures it: treat early in the season or at the first sign of disease, because it won't eliminate an infection that is already present.[3]
- Don't spray African violets, begonias, Boston ferns or geraniums, and don't use it on crops grown for sale.[3]
- Fruit and nut trees qualify only if they won't bear harvestable fruit for at least 12 months after spraying, and fruit from treated crabapples isn't for eating.[3]
- For a lawn, measure the area first (length times width) and plan to treat the whole lawn, after mowing or when the spray can dry before the next mowing. Your county Extension service can help identify lawn and ornamental diseases.[3]
3. Mixing
- Shake well. Use a jar-type concentrate-plus-water sprayer, a pump-up sprayer or a dial-style hose-end sprayer, not a hose-end sprayer that has only an on/off switch or refills with water as you spray. One tablespoon is ½ fl oz.[3]
- Lawns: 5 fl oz in 1 gallon of water per 250 sq ft for brown patch, Fusarium and pink patch, snow molds, take-all, summer patch, red thread, yellow patch and zoysia patch; 3 fl oz per gallon per 250 sq ft for dollar spot, gray leaf spot, rust, powdery mildew, anthracnose, leaf spot, stripe smut, spring dead spot and necrotic ring spot.[3]
- Roses and flowers: 1 tablespoon per gallon for powdery mildew, 2 tablespoons for black spot and rust. Trees and shrubs: ½ to 3 tablespoons per gallon depending on the plant and disease, never more than 1½ fl oz per gallon.[3]
4. Applying
- On lawns, spray evenly over the measured area. Unless the disease table says otherwise, treat at the first sign and repeat every 21 days until the grass recovers; brown patch can be repeated every 14 days, with the first spray in May or June before it shows.[3]
- Lawn limits: no more than 20 fl oz per 1,000 sq ft per application, 160 fl oz per 1,000 sq ft a year, and 8 applications a year.[3]
- Spray roses, flowers, trees and shrubs to the point of runoff. Roses are treated every 10 days from bud break, with no more than 18 applications or 36 fl oz per 1,000 sq ft a year.[3]
5. After you spray
- Keep adults, children and pets out of the treated area until the spray has dried. On roses, flowers, trees and shrubs, let it dry fully before watering.[3]
- Don't graze animals on treated lawns or feed the clippings to livestock or poultry, and don't use the measuring cups or spoons for food again.[3]
First aid
- If swallowed, call a poison control center or doctor right away and have the person sip a glass of water if able to swallow. Don't induce vomiting unless told to, and give nothing by mouth to an unconscious person.[3]
- Have the container or label with you when you call or go for treatment; SafetyCall, (866) 897-8050, also gives emergency treatment information.[3]
Storage, spills and disposal
- Store it in a cool, dry area away from children, pets, heat and open flame.[3]
- Don't reuse the empty container: rinse a container of 5 gallons or less three times (¼ full of water, capped and shaken 10 seconds, rinse water into the sprayer), then recycle or trash it. For leftover product, call your local solid waste agency or 1-800-334-9481, and never pour it down a drain.[3]
From the safety data sheet
- The material safety data sheet for Ferti-lome Liquid Systemic Fungicide II, the Ferti-lome pack of this registration (a clear, light-amber liquid with 1.55% propiconazole), says it may cause eye and skin irritation and is toxic to fish and aquatic organisms. It calls the product a moderate eye irritant that can cause substantial but temporary eye injury, depending on how much gets in and how quickly the eye is rinsed.[4]
- Its acute figures, based on data for a similar formulation, are an oral LD50 of 4,340 mg/kg, a dermal LD50 above 2,020 mg/kg and a 4-hour inhalation LC50 above 2.6 mg/L. It says propiconazole is not a skin sensitizer, names the liver as a possible target organ, and notes that liver tumors increased in male mice given extremely high doses.[4]
- The sheet asks for goggles or a face shield when handling the concentrate or applying the diluted spray, plus long pants, a long-sleeved shirt, socks and shoes. Launder contaminated clothing separately, and wash hands and skin with soap and water afterward. It says no special respiratory protection is needed when the product is applied according to the label.[4]
- For the environment it describes propiconazole as toxic to fish, low in toxicity to wildlife and nontoxic to bees. It gives an aerobic soil half-life in the dark of more than a year and medium to low mobility in soils.[4]
- Store it in a cool, dry area away from heat, animal feed, food and household cleaning products. For a small spill, put on rubber gloves, soak it up with an absorbent material and sweep it up. It isn't regulated for shipping by DOT or IMDG.[4]
Safety and environmental hazards
People
Both labels carry the CAUTION signal word: the products are harmful if swallowed, and Banner MAXX II also causes moderate eye irritation. Banner's label says not to enter treated areas without protective clothing until sprays have dried.[1][3]
Pets
Don't graze animals on treated areas or feed clippings to livestock or poultry. PPZ 1.55's label adds that it must not be sprayed so it contacts people or pets, directly or through drift, and that pets stay out until the spray has dried.[1][3]
Bees and pollinators
Neither label carries a bee hazard statement; their environmental warnings are for fish and shrimp.[1][3]
Fish and water
Toxic to fish and shrimp; don't apply directly to water or where surface water is present.[1][3]
