Disease Monitor - 4 predictive models

Why do I need a disease monitor?

Fungal diseases can wipe out an entire harvest. But you don’t have to spray “just in case”! VineyardElf analyzes the weather and tells you when there is a real infection risk.

This way you can:

• Spray only when it’s actually needed
• Save on plant protection products
• React before the disease develops

Which diseases do we monitor?

Powdery Mildew

A white, powdery coating on leaves and fruit. The Gübler-Thomas model assesses risk based on nighttime temperatures.

Downy Mildew

Yellow spots on leaves with a grey coating underneath. The Mills Rule model analyzes rainfall and humidity.

Black Rot

Dark spots and mummification of the fruit. The Cornell/Spotts model assesses the risk.

Botrytis (Grey Mould)

A grey, fluffy coating on the fruit. The IFV/UC Davis model evaluates infection conditions.

Tab navigation

The disease monitor uses tab navigation - each disease has its own tab:

• 🍂 Downy Mildew
• 🌫️ Powdery Mildew
• ⚫ Black Rot
• 🍇 Botrytis (Grey Mould)

In each tab you’ll find:

• A pie chart with the current risk %
• Weather conditions that favor the disease
• Symptoms and protection recommendations
• A risk history chart

Actions section

Below the disease tabs there is an actions section that is always visible:

• 💧 Apply spray - add a treatment to the log
• 🧪 Demo mode - test the system with different scenarios
• 🔔 Notify at 90% - set up alerts
• 📈 View history - data archive

Demo mode

Click the “Demo mode” button to see how the system behaves at different risk levels:

• 🟢 Low (25%)
• 🟡 Medium (55%)
• 🟠 High (78%)
• 🔴 ALERT (100%)

You can also simulate a spray and see how the protection indicator changes.

How to read the results?

How to set up alerts?

1. Click the “🔔 Notify at 90%” button
2. Set the alert threshold (90% by default)
3. Save - done!

When the risk crosses the threshold, you’ll get a notification via SMS, email or WhatsApp.

Tip: Set the alert at 40-50% - this gives you time to react before the risk becomes critical.
