Normal Soil
32 oz. N2-GROW  per acre

Aid in air and water exchange

Grower's Source water management tools aid in air and water exchange which is critical in stimulating microorganisms in preparation for planting.  OVERHAUL™ also detoxifies and flushes harmful effects of sodium or carryover herbicides.


NOTE: *For pH higher than 6.8 and/or high sodium content use OVERHAUL.  Also good for chemically damaged fields.

*Alkali/Sodium Soil
32 oz. OVERHAUL™ per acre

8 oz. REVAMP™ per acre in watering solution

Spray in the seed row over the top of the seed

Stimulate microorganisms and spur root growth
This application will stimulate organisms creating an environment promoting a bigger root system and faster growth in the plant.
Normal Soil
32 oz. N2-GROW per acre
Beneficial air and water management exchange
Enzyme action at this stage helps the plant prepare for regeneration.  In sodium soils, the plant is very susceptible to sodium uptake and cell eruption causing cell lesions creating a favorable environment for disease.  OVERHAUL™ aids in flushing the sodium from the soil.

32 oz. OVERHAUL™ per acre
Adding Grower's Source to Your Spray Program

1st spraying: 
per acre

Subsequent sprayings: 16 to 32 oz. FOLIARFEED per acre

Strong root and top growth - eliminating 2 or 3 sprayings per season

Grower's Source™ enhances the effects of herbicides, fungicides or insecticides.  Aids in leaf intake of given application.  At 1st spraying, the plant still needs the large dose of phosphorus for strong root growth.  Later very little nitrogen is needed for top growth, but potatoes become heavy users of phosphate and potassium at this stage for crop growth and disease resistance.


Each spray application can be applied with most fungicides and/or insecticides.  We suggest using their lowest recommended label rates.  FOLIARFEED helps make the fungicides and insecticides act in a systemic way for longer retention and kill effects.  Most farmers extend spray program 2 to 4 days beyond normal rotation, eliminating two or three sprayings per growing season.

Herbicide Spray Program

Apply 16 fl. oz. WILDFIRE™ per 100 gallon tank mix with contact herbicides.

Fungicide Spray Program

Apply 16 - 32 fl. oz. SSS™ per 100 gallon tank mix with fungicide.

Insecticide Spray Program

Apply 16 - 32 oz. INSECT-X-CITER™ per 100 tank mix with insecticides.

Note about Spraying:

We strongly recommend using an adjuvant with your spray program. Grower's Source™ specialty surfactants (SSS™, N2-GROW™, WILDFIRE™, INSECT-X-CITER™) have proven cost effective with spray applications of chemicals (fungicides, herbicides, pesticides) to allow lowest label rates with better results. The synergy can add potency and extend the chemical life and have allowed some growers to experiment and get exceptional results with well under label rates.

Please ask your Grower's Source™ representative for the appropriate product for your needs and grower's experiences in your area.
