Directions and Usage

Application rates should be based on tissue or petiole analysis. On plants with waxy leaf surfaces, 12 ounces (355 mL) of a non-ionic wetting agent per 100 gallons (380 L) of finished spray will aid leaf penetration.
Add Extreme Green 20® to half of the water, then agitate while adding remaining water. Add urea or other fertilizers.
Add herbicides last while continuing to agitate tank contents.

Apply Extreme Green 20® at a rate of 0.125 - 0.5 lbs. (2-8 ounces-dry weight) per 1,000 ft2 (5.5 - 22 lbs. / Acre). Apply every 2 - 8 weeks based on desired color response.

Spray solution as soon as possible. Extreme Green 20® tank mixes are generally stable; however, agitate prior to spraying if mix has been standing for over 24 hours. Use sufficient water for good coverage. For optimum results, do not apply water for at least 4 hours following application. Do not apply to flower buds or blossoms of flowers, shrubs and trees.
