Evaluation of pesticide OFB Eden on Leafhopper

The following evaluation was performed in the United States:

Evaluations were conducted to test the performance of "OFB Eden" against the western grape leafhopper, Erythroneura elegantula a common pest of table, raisin and wine grape, Laboratory bioassays and small plot trials were used to test and demonstrate the potential for using "OFB Eden" against the grape leafhopper and possibly other leafhopper pests.

The laboratory bioassays revealed that "OFB Eden" dilutions of 150 and 300:1 (6,666 and 3,33 3ppm) resulted in virtually I 00 percent mortality of all stages of the grape leafhopper including the adult stage. It was also observed that nymphs succumbed to the "OFB Eden" applications within 36 hours under indoor conditions and less than 12 hours under field conditions. Grape leafhopper mortality was not significantly affected by differences in "OFB Eden" concentration.

From the results of this preliminary screen it can be concluded that "OFB Eden" demonstrated consistent effectiveness against a significant leafhopper pest at both concentrations and under the different environmental conditions of the trials. These results also suggest "OFB Eden" may be effective against other economically significant leafhopper species in other agricultural crops.
