STRETTA™ is a patented, plant-derived water
management product that improves plant health and
increases crop yields by maintaining plant available
moisture during periods of stress. Irrigation water treated
with STRETTA easily moves throughout the plant root
zone, reduces runoff and allows growers to produce
crops using less water and energy.
WHY USE STRETTA:
n Reduce plant stress
n Optimize yield
n Improve irrigation efficiency
FEATURES AND BENEFITS:
APPLICATION INTERVAL:
n Increases wetting – reduces runoff and
n Every 3 to 4 weeks, starting at crop
leaching
n Holds available water – conserves
water and energy
n Plant-derived – environmentally sound
USE RATES:
n First application at 2 quarts per acre
(4.68 liters per hectare)
n Make subsequent applications at 1
quart per acre (2.34 liters per hectare)
n Adjust use rates based on climatic
conditions and the needs of the crop
establishment
n The timing between applications may
vary by crop, soil type or environmental
conditions
PACKAGING:
n 2 X 2.5 gallons per case
n 275 gallon tote

Growers are under increasing pressure to produce more food with
less water. Crops grown on coarse soils often experience periods of
stress that lead to reduced plant health and yields.

Trials demonstrate that applying STRETTA through the
irrigation system allows growers to increase crop yields
and reduce irrigation inputs.

REDUCED CROP INPUTS
STRETTA increases crop yields, plant health and the grower’s return on crop inputs. This includes a
reduction in water requirements, which results in less fuel or electricity for irrigation pumps as well as
environmental benefits of reduced water consumption. Two ways a grower can reduce the use of
irrigation water with STRETTA are by decreasing irrigation times or increasing time between watering.
