Azoxystrobin is one of the most widely used systemic fungicides for turfgrass, lawns, golf courses, and landscapes. If you’re using Azoxy 2SC or Artavia 2SC, getting the application rate right is critical—not just for effectiveness, but also for safety, cost efficiency, and plant health.
That’s where an Azoxystrobin Fungicide Application Calculator becomes essential. Instead of guessing or manually calculating ounces per gallon, a calculator helps you determine the exact amount of fungicide needed based on your lawn size and target disease.
This guide covers everything you need to know—how the calculator works, mixing ratios, disease-specific rates, and real-world application tips.
What Is Azoxystrobin?
Azoxystrobin is a broad-spectrum systemic fungicide belonging to the strobilurin (QoI) class. It works by inhibiting fungal respiration, effectively stopping disease growth at the cellular level.
Key Benefits
- Prevents and controls a wide range of lawn diseases
- Systemic action (absorbed into plant tissue)
- Long residual activity (2–4 weeks)
- Works as both preventative and curative treatment
Common Products
- Azoxy 2SC (generic azoxystrobin 22.9%)
- Artavia 2SC (brand formulation with same active ingredient)
Why Use an Azoxystrobin Calculator?
Applying too little fungicide can lead to treatment failure, while too much can:
- Damage turf
- Waste product
- Increase resistance risk
A calculator removes the guesswork by helping you determine:
✔ Exact amount of fungicide needed
✔ Water volume for mixing
✔ Application rate per 1,000 sq ft
✔ Low vs high disease pressure dosing
Understanding Application Rates
Azoxystrobin rates are usually given in:
- Fluid ounces per 1,000 sq ft
- Sometimes per acre (43,560 sq ft)
Typical Label Rates
| Application Type | Rate (oz per 1,000 sq ft) |
|---|---|
| Preventative | 0.2 – 0.4 oz |
| Curative | 0.4 – 0.8 oz |
| Severe cases | Up to 1.0 oz |
How the Azoxystrobin Calculator Works
A standard fungicide calculator uses three inputs:
1. Target Disease
Different diseases require different rates.
2. Application Rate (Low or High)
- Low rate = prevention
- High rate = active infection
3. Lawn Size (Square Feet)
Total treatment area
Formula Behind the Calculator
The core formula is simple:
Total Product Needed = (Lawn Area ÷ 1,000) × Application Rate
Example Calculation
- Lawn size: 5,000 sq ft
- Rate: 0.5 oz per 1,000 sq ft
Calculation:
5,000 ÷ 1,000 = 5
5 × 0.5 = 2.5 oz of fungicide
Mixing Azoxy 2SC or Artavia 2SC
Azoxystrobin is typically applied using a pump sprayer or backpack sprayer.
General Mixing Guidelines
- Use 1–2 gallons of water per 1,000 sq ft
- Ensure even coverage
- Agitate solution during spraying
Example Mixing Scenario
For 2.5 oz product (from previous example):
- Water needed: 5,000 sq ft × 1 gal = 5 gallons
- Mix: 2.5 oz fungicide in 5 gallons water
Disease-Specific Application Rates
Different lawn diseases require different strengths of application.
1. Brown Patch (Rhizoctonia)
- Low rate: 0.4 oz
- High rate: 0.8 oz
Tip: Apply in warm, humid conditions when disease is active.
2. Dollar Spot
- Low rate: 0.2 oz
- High rate: 0.5 oz
Tip: Frequent applications may be needed.
3. Powdery Mildew
- Rate: 0.3 – 0.5 oz
Tip: Improve airflow along with treatment.
4. Rust
- Rate: 0.4 – 0.6 oz
5. Leaf Spot
- Rate: 0.4 – 0.8 oz
6. Pythium Blight (Limited Control)
- Use higher rates
- Combine with other fungicides for best results
Preventative vs Curative Applications
Preventative Application
- Apply before disease appears
- Use lower rate
- Repeat every 14–28 days
Curative Application
- Apply when disease is visible
- Use higher rate
- Repeat every 7–14 days
Sprayer Calibration (Critical Step)
Before applying fungicide, calibrate your sprayer.
Steps:
- Fill sprayer with water only
- Spray a known area (1,000 sq ft)
- Measure water used
This ensures:
- Accurate coverage
- Correct fungicide concentration
Application Tips for Best Results
1. Apply Early Morning or Evening
- Avoid midday heat
- Prevent evaporation
2. Watering
- Light irrigation after application helps absorption
- Avoid heavy watering immediately
3. Even Coverage
- Overlap spray paths slightly
- Avoid streaking
Common Mistakes to Avoid
❌ Overapplication
- Can damage turf
- Waste product
❌ Underapplication
- Leads to poor disease control
❌ Incorrect Mixing
- Always measure accurately
❌ Ignoring Weather
- Rain can wash away product
Resistance Management
Azoxystrobin belongs to the QoI fungicide group, which is prone to resistance.
Best Practices:
- Rotate with other fungicides
- Do not apply repeatedly without breaks
- Use tank mixes when needed
Safety Guidelines
Personal Safety
- Wear gloves and protective clothing
- Avoid inhalation or skin contact
Environmental Safety
- Keep away from water bodies
- Follow label instructions strictly
Azoxy 2SC vs Artavia 2SC
| Feature | Azoxy 2SC | Artavia 2SC |
|---|---|---|
| Active Ingredient | Azoxystrobin | Azoxystrobin |
| Strength | 22.9% | 22.9% |
| Performance | Same | Same |
| Branding | Generic | Premium |
👉 Functionally, both are identical—the calculator works the same for both.
Advanced Calculator Use Cases
Large Lawns (10,000+ sq ft)
- Use backpack or tow sprayer
- Calculate in bulk
Spot Treatment

- Adjust proportionally
Example Scenarios
Scenario 1: Preventative Treatment
- Lawn: 3,000 sq ft
