Stoller Creates Solutions

Solving Grower’s Biggest Challenges Creating More Yield, Quality, and Profit.

Roots are the “Brains” of The Plant

Build a Better Plant, Build a Better Yield.

Build a Better Plant, Build a Better Yield.

Who is Stoller? We are Excellence in Plant Performance™

What we do:

We are driven to teach and help growers get the most out of the investment they put into the crops they produce, from corn and soybeans to almonds, tomatoes, pineapples and everything in between.

How we do it:We do this by understanding in depth how a plant functions, what a plant needs, and more importantly how to manipulate a plant to achieve desired results.

Our tools to accomplish this:We work with plant nutrition, plant hormones, and other signaling molecules to achieve our growers goals.

“We are dedicated to helping growers understand and naturally enhance the genetic potential of plants.”– Jerry Stoller

Critical Plant HormonesThere are five key hormones:

1. Cytokinin

2. Auxin

3. Gibberellic Acid (GA)

4. Ethylene

5. Abscisic Acid (ABA)

Understanding Plant Hormones and Growth Effects

Challenge - Lodging

Understanding Plant Hormones and Growth Effects

Causes:Too much NitrogenHigh WindsPlant is too tallHigh Plant Population

True Cause – lack of cytokinin

Cytokinin ??????

#WeAreStoller

• Cytokinin (CK)– “Youthful” shoot

hormone– Cell division and

differentiation – Produced in actively

growing tissues roots, embryos, and fruits

– Controls apical dominance and promotes above ground branching and growth.

– Promotes delayed senescence

• Auxin (AX)– The “rooting”

hormone– Cell division and

differentiation, stimulates cell elongation in young shoots

– Produced in apical meristem (growth tip of the shoot)

– Promotes lateral root growth and root branching.

Auxin Moves Downward

Cytokinin Moves Upward

AXCK

Cytokinin and Auxin have an inverse relationship, depending upon ratio within the plant determines

the type of growth a plant will produce.

6 varieties – 3-6 Row Varieties, 3-2 Row varietiesResults are similar more leaf mass, and in general a shorter statured plant with thicker stem walls.

Challenge – “Pin” Barley Mid-Grain Development abortion of Grains

Lack of Plumpness

Understanding Plant Hormones and Growth Effects

Causes:Lack of WaterLack of EnergyHigh Temperature

True Cause –Localized Cytokinin Deficiencies

Grains Abort due to 1- lack of energy2- lack of cytokinin to drive cell division

Challenge – Pre-Harvest Head Sprout

Understanding Plant Hormones and Growth Effects

Causes:High moisture near harvestDelayed harvestIncreased risk with lodged fields

True Cause:High levels of GA in comparison to ABA

#WeAreStoller

Challenge – Straight Cutting BarleyBarley can be highly variable in moisture at harvest.

Stoller Solution – Sugar Power-Evens harvest moisture

This is showing up in nearly every crop, this treatment has the smallest standard deviation in harvest moisture.
