Fundamental Instructions for Applications and Programs

Very Important 
Most liquid products are designed to be foliar absorbed. For maximum performance, apply early in the morning or late in the evening with 1-2 gallons of water per 1,000 sq ft (300-600 L / Ha). Allow the application to dry on plant 3-6 hours before watering.

GRIGG™ Ultraplex® is a foliar nutrition product that contains a non-ionic organic surfactant and no additional surfactant is necessary when using this product. Ultraplex is also an effective water buffering agent designed to resist large changes in spray tank pH. It is a critical foundation product and should be the first thing added to the water of your spray tank mix. The recommended rate for Ultraplex is 3 fl oz per 1000 sq ft (10 L / Ha). Ultraplex may be used with other manufacturers’ products to increase their overall compatibility and spray efficiency.

GRIGG™ Proven Foliar® nutrients are compatible with each other and most fungicides, herbicides, and pesticides when tank mixed at recommended rates. A jar test is always recommended as a part of standard operating procedure. The high degree of compatibility of the Proven Foliar line includes the ability to be mixed with other foliar applied fungicides, insecticides and herbicides that do not need to be watered in. When mixing with herbicides, consider using the lowest label rate as GRIGG products may enhance the uptake of the herbicide.

Unless otherwise stated, the rates expressed in GRIGG nutrition programs are expressed as Fluid Ounces Per 1,000 square feet with Litres Per Hectare equivalents. To convert 14 day programs to 7 day programs lower rates by one third (1/3).

GRIGG straight chelated nutrients or any other Proven Foliar nutrient can be added to any program as indicated by soil and tissue test results. Typical rates for adding individual micronutrients range between 1-3 fl oz per 1,000 sq ft (3-10 L / Ha). For severe deficiencies, as much as 6 fl oz per 1,000 sq ft (20 L / Ha).

Soils Bio-Amendment Program 
For sand based greens, use 1 gallon per acre (10 L / Ha) of GRIGG™ Bio Blend™ and 4 gallons per acre (40 L / Ha) of GRIGG™ Carboplex® applied monthly and lightly watered in. For soil based greens use 1/2 gallon per acre (5 L / Ha) of Bio Blend and 2 1/2 gallons per acre (25 L / Ha) of Carboplex.

Program Balance
GRIGG Proven Foliar nutrients are an effective method of providing nutrients to the plant. However, we also recommend using GRIGG™ GreenSpec® granular nutrients in the spring and fall as determined by soil testing to complete a total program. No other brand of products has been proven to enhance the performance of any GRIGG products.

Unless otherwise stated, GRIGG nutrition programs should typically be applied every 7-14 days. There is flexibility to accommodate differing management styles and between 1 to 3 weeks is acceptable if rates are adjusted accordingly.
