The 14-day window that decides when we spray.
We schedule inside a two-week forecast from a specialist weather partner. It tells us when a pass will hold and when it would be washed off, and it is the reason so much of our spraying happens after dark.
Why the forecast comes first
Spray a pesticide and get rain right behind it, and most of the product washes into the soil. For fertilizer that is not a disaster. For pesticide it is money and effort gone, and the weeds are still there.
A reliable window of about two weeks changes how we plan. Instead of reacting to the sky on the morning of the job, we can book the pass into the best stretch of days and move it early if the forecast shifts. The window is what makes a regional spray calendar possible at all.
What we watch
- Rain
- Anything soon after the pass washes pesticide off the plant and into the soil.
- Wind
- Moves the spray off target. We hold for calm air, which usually means evening and night.
- Humidity
- Relative humidity affects how droplets carry and how long they stay on the leaf.
- Inversions
- A temperature inversion traps spray in a layer of still air. It has a profound effect on drift.
Why so much of it happens at night
The winds are calmer at night. There are no pollinators working. Those two facts make the evening and the night the best time to put a product on a field, and the drone does not care that the sun is down. If you book with us, expect the pass to land in those hours more often than not.
