The season
A Prairie year, stage by stage.
What generally goes on and when, from fall granulars to post-harvest perennials. Every product and crop has its own label window.
- 01
Fall
After harvest, before freeze-up
Soil-applied granulars go down ahead of the next crop.
- 02
Burnoff
Pre-seed, killing what is up
Clean the field before seeding. Bring a second group with glyphosate, especially against kochia.
- 03
Seeding
On the seed or in the soil
Seed treatments and soil residuals protect the crop while it gets established.
- 04
Early in-crop
Seedling to early tiller or rosette
Small weeds and flea beetles. Timing here pays off all year.
- 05
In-crop
The main spray window
The main herbicide window, set by crop and weed staging.

Flag and bloom
Flag leaf, heads, flowering
Disease protection is timing-critical. Sclerotinia and fusarium windows are short.
- 07
Pre-harvest
Dry-down and late weeds
Even dry-down and late perennial control. Staging and pre-harvest intervals matter.
- 08
Post-harvest
Perennials and winter annuals
A strong time to hit perennials and winter annuals while they move sugars to the roots.
