How every program works

One granular base. One liquid package. Timed by growth stage.

Rates are per plant, per tree or per acre, listed on each crop.

2 · LiquidsThe same five liquids, tank-mixed

    Per acre, or per 100 gallons of mix.

    3 · TimingSprayed at each growth stage

    Planting, early growth, bloom, fruit set and after picking. Each crop lists its own timings.

    Built from programs Sigma's agronomy team runs on working farms, including THE FARM at Okefenokee in Folkston, Georgia. Months shown are for south Georgia; shift them for your region.

    Season plans are being updated. Our agronomy team is adding new field data to these plans. Updated plans will post over the coming week.
