Control of Aphids using OFB Eden - Lab Test
Evaluations were conducted to test the performance of "OFB Eden" against four conunon aphid pests of landscape and interior grown ornamental plants. Laboratory bioassays were used to define the dose-mortality relationship between "OFB Eden" and the melon aphid, Aphis gossypii, the rose aphid, Macrosiphum rosae, the green peach aphid, Myzus persicae and the bean aphid, Aphisfabae. Whole, potted ornamental plants infested with aphids were used to test the practical use of "OFB Eden" for controlling aphids on plants and to evaluate any residual or repellent action attributable to "OFB Eden".
The laboratory bioassays revealed that "OFB Eden" at dilutions of 150 and 300:1 (6,666 and 3,333ppm) resulted in virtually 100 percent mortality of all aphid species tested. At the lowest concentration of 600:1 (1,666ppm), 90 percent or more of the pests were killed, but also indicated potency may begin to decrease at this concentration. It was also observed that aphids required approximately 36 hours to succumb to the "OFB Eden" applications. 'Be time to aphid death appeared to be independent of temperature but may be affected by "OFB Eden" concentration.
Results of the potted plant trials demonstrated that as a practical pest control tool "OFB Eden" effectively rescued aphid-infested plants using a single application of the product. Results of the residual activity and repellency tests though revealed no significant residual mortality to aphids when introduced to previously sprayed plants. These tests also indicated there was no repellency response to aphids within 24 hours of application.
From these evaluation trials it can be concluded that "OFB Eden" was demonstrated to be an effective control agent of aphids at 600:1 (1,666ppm) or greater concentration. The tests also revealed that as a pest control tool, "OFB Eden" consistently controlled aphid populations within 36 hours of application and was effective under a broad range of conditions consistent with many home and commercial applications. "OFB Eden" proved easy to mix into solution and left virtually no visible residual on leaf surfaces.
