WAT E R M A N A G E M E N T S T R E T TA ™ I R R I G AT I O N S U R FA C TA N T 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 D ATA S U M M A R Y 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. 90 Fruit weight/acre (cwt) 80 Increased Squash Yield & Water Savings 70 n Crop: yellow squash 60 n Soil: fine sand 50 n Treatments: 100% irrigation (3 hrs/day), 60% irrigation, STRETTA @ 60% irrigation 40 30 n Application rates: STRETTA @ 2 qts/acre, STRETTA @ 1 qt/acre 20 n Method of application: drip injected 10 n Application frequency: 3 to 4 weeks 0 n No. applications: 2 100% water control 60% water control STRETTA @2 qt/acre 60% water control STRETTA @1 qt/acre 60% water control 200 Soil compaction (psi) 180 Decreased Soil Compaction 160 n Soil: fine sand 140 n Treatments: 100% irrigation (3 hrs/day), 60% irrigation, STRETTA @ 60% irrigation 120 100 80 n Application rates: STRETTA @ 2 qts/acre, STRETTA @ 1 qt/acre 60 n Method of application: drip injected 40 n Application frequency: 3 to 4 weeks 20 n No. applications: 2 0 100% water control 60% water control STRETTA @2 qt/acre 60% water control STRETTA @1 qt/acre 60% water control Fruit weight/acre (cwt) 300 Increased Tomato Yield & Water Savings 250 n Crop: fresh market tomato 200 n Soil: fine sand 150 n Treatments: 100% irrigation (3 hrs/day), 60% irrigation, STRETTA @ 60% irrigation 100 n Application rates: STRETTA @ 2 qts/acre, STRETTA @ 1 qt/acre n Method of application: drip injected 50 0 n Application frequency: 3 to 4 weeks n No. applications: 3 100% water control 60% water control STRETTA @2 qt/acre 60% water control STRETTA @1 qt/acre 60% water control D ATA S U M M A R Y Trials demonstrate that applying STRETTA through the irrigation system allows growers to increase crop yields and reduce irrigation inputs. 2.5 14% less water used Increased Romaine Lettuce Yield & Water Savings Harvest plant weight (lb) 2.0 n Crop: Romaine lettuce n Soil: sandy loam 1.5 n Treatments: grower standard, frequency adjusted (tensiometer), STRETTA @ frequency adjusted 2 qts/ acre, STRETTA @ frequency adjusted 1 qt/acre 1.0 n Method of application: drip injected n Application frequency: 3 to 4 weeks 0.5 n No. applications: 3 0.0 Grower Standard Frequency Adjusted (FA) FA/STRETTA 1 qt/acre FA/STRETTA 2 qt/acre 140 n Crop: Strawberry n Soil: fine sandy loam n Treatments: grower standard (1 to 2 hrs/day), STRETTA @ grower standard n Application rate: 2 qts/acre n Method of application: drip injected n Application frequency: 3 weeks n No. applications: 5 Yield difference vs control (%) Increased Early Strawberry Yield 130 120 110 100 90 80 December January STRETTA Total Control 4.0 Decreased Corn Stress 3.5 n Treatments: 100% water, STRETTA @ 100% water, STRETTA @ 75% water n Application rates: 2 quart/ acre, followed by 1 quart/ acre n Method of application: overhead sprinkler n Application frequency: 4 weeks (1 = High Stress 5 = No Stress) n Soil: fine sandy loam Drought stress @78 days (1-5) n Crop: Field corn n No. applications: 4 3.0 2.5 2.0 1.5 1.0 0.5 0.0 CONTROL @ 100% WATER STRETTA @ 100% WATER 220 STRETTA @ 75% WATER Increased Corn Yield n Crop: Field corn 200 Grain yield (bu/a) CONTROL @ 75% WATER n Soil: fine sandy loam n Treatments: 100% water, STRETTA @ 100% water, STRETTA @ 75% water 180 n Application rates: 2 quart/ acre, followed by 1 quart/ acre 160 n Method of application: overhead sprinkler 140 n Application frequency: 4 weeks 120 n No. applications: 4 100 CONTROL @ 100% WATER STRETTA @ 100% WATER CONTROL @ 75% WATER STRETTA @ 75% WATER 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.
