TAMARACK® Plant Nutrient
Introduction
TAMARACK is a specialty plant nutrient based on amino acids and peptide chains
from hydrolyzed proteins. TAMARACK may be applied as a foliar spray or soil
applied via fertigation, drip, or drench. TAMARACK was commercialized in the
1970s and is sold in various countries around the world.

Benefits of TAMARACK
•Enhances yield (quantity and quality) under normal and stressed growing
conditions by increasing development and retention of fruit and flower set via
enhancement of pollen germination.
•Mitigates yield losses under stress conditions (salinity, extreme temperatures,
drought, etc.) especially in conjunction with critical plant developmental stages
(i.e. during rapid growth, flowering and/or fruit set).
•Does not need an adjuvant to be mixed with water and is tank-mix compatible
with herbicides, fungicides or insecticides.
Mechanisms of Action
•Gene activation - plant gene response to stress conditions is boosted by
Tamarack for quicker recovery from stress.
•Improves nitrogen use efficiency – activates key plant enzymes involved in nitrogen
metabolism for improved growth and yield.
Application
Timing
Broadleaf Crops:
flowering through fruit set
and sizing periods.
Grass Crops: early boot
and heading through
flowering and grain fill.
Use Recommendations
TAMARACK applications may begin as early as the vegetative growth stages but most importantly should occur during the critical
reproductive phases from flowering to fruit set through the fruit sizing and quality setting periods.
Rate: 1 to 2 pts/acre*
Application Number: 1 to 3*
Application Timing:
•Broadleaf Crops: flowering through fruit set and sizing periods
•Grass Crops: early boot and heading through flowering and grain fill
Compatibility: Tamarack is compatible with most commonly used fertilizers and pesticides. A jar test may be used to quickly
confirm compatibility with specific tank mixtures.
*Always read and follow the Precautions and Direction for Use as listed on the label.
