How to Read Mountain Weather Before Spraying

The Spray Window

Ideal conditions: wind below 15 km/h, relative humidity below 80%, no rain in the previous 6 hours or next 4 hours, temperature between 15°C and 30°C. These conditions are most common between 7AM and 11AM in most Himalayan locations.

Wind

Check wind direction, not just speed. Spray moving toward your neighbour's orchard is drift — it wastes your chemical and can damage their crops. Spray early morning when valley winds are still calm.

Humidity

High humidity (above 80%) means your spray droplets evaporate slowly and leaves stay wet longer — which paradoxically can encourage fungal disease. Check your phone weather app or the Baagicha weather page.

Rain Forecast

If rain is forecast within 4 hours of spraying, skip the application. Systemic fungicides need at least 2 hours to be absorbed; contact fungicides need 6 hours. A washed-off spray is wasted money.
