Abstract/Contents: | "Experiments were conducted under controlled environment growth room (indoor) and outdoor conditions to determine the quantity of 2,4-D recovered in water collected after lateral runoff from the surface of Poa Pratensis sod. When runoff water was collected immediately after application of the herbicide at a dose of 1 kg a.e./ha to turfgrass grown under indoor and outdoor conditions, 91 and 71% of the applied 2,4-D was present in the effluent water, respectively. Within 1, 2, 6, and 10 days after application of the herbicide to turfgrass grown indoors, 65, 55, 50, and 32% of the 2,4-D dose was recovered in the runoff water, respectively. When compared to the quantity of 2,4-D recovered per flat at time 0, there was a 30, 55, and 65% decrease in the recovery 1, 6, and 10 days after treatment, respectively. Within 0.5, 1, 2, 7, and 11 days after application of the herbicide to turfgrass grown outdoors, 57, 48, 32, 25, and 12% of the 2,4-D dose was recovered in the runoff water, respectively. When compared to the quantity of herbicide recovered at time 0, there was a 20, 55, and 83% decrease 0.5, 2, and 11 days after treatment, respectively. Two weeks after treatment, approximately 10% of the applied 2,4-D was still present in the runoff water from sod growth outdoors." |
