Macro-Sorb Foliar and Radicular can improve your turf's stress tolerance
Macro-Sorb Foliar and Radicular deliver high-concentration free amino acids in a formulation specifically designed to promote plant stress tolerance and defenses to biotic and abiotic factors
Stress Defense Program:
Apply 1-2 oz. Macro-Sorb Foliar per 1000 sq. ft. every 7-14 days, and 4 oz. Macro-Sorb Radicular per 1000 sq. ft. every 14 days throughout the growing season.
During periods of prolonged or severe stress, apply 2 oz. Macro-Sorb Foliar per 1000 sq. ft.
on a weekly basis.
MACRO-SORB TURF STRESS RESEARCH
Effects of a Biostimulant on the Heat Tolerance Associated with Photosynthetic Capacity, Membrane Thermostability, and Polyphenol Production of Perennial Ryegrass
Kauffman, G. L., D. P. Kneivel, and T. L. Watschke. 2007
This study, published in the peer-reviewed scientific journal Crop Science, demonstrates how Macro-Sorb Foliar improves the ability of turfgrass to photosynthesize during heat stress compared to control turfgrass plants
Macro-Sorb Foliar and Macro-Sorb® Radicular
Increase Drought Stress Tolerance of Annual Bluegrass
Dr. Watschke & Borger, Penn State
During stressful conditions, plants are unable to perform normal synthesis of amino acids. By applying amino acids prior to the onset of drought stress, plants are able to prolong wilting and also recover from wilting faster. This study was aimed at determining the impact of Macro-Sorb® Radicular (4.0 fl oz/M), Macro-Sorb® Foliar (2.0 fl oz/M), and Radicular + Foliar (4.0 + 2.0 fl oz/M) applications to annual bluegrass prior to the onset of drought stress. Applications were applied to annual bluegrass every 10 days for a total of 6 applications. Following applications, irrigation was completely removed and plants were evaluated for wilt. Plants treated with Macro-Sorb® Radicular or Macro-Sorb® Foliar took longer to wilt (Figure 1.), and recovered quicker from wilting compared to the untreated control plants (Figure 2.).
