Evaluation of Pesticide OFB Eden on Cabbageworm
Evaluations were conducted to test the performance of "OFB Eden" against the imported cabbageworm, Pieris rapae a common pest of crucifers and other row crops. Laboratory bioassays and small plot trials were conducted to test and evaluate the potential for using "OFB Eden" against caterpillar pests.
Laboratory bioassays revealed that "OFB Eden" dilutions of 150 and 300:1 (6,666 and 3,333ppm) resulted in significant mortality of cabbage worms feeding on kale. The early instars (1" through 3d) appeared most susceptible. Cabbage worm 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 caterpillar 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 caterpillar species in other agricultural crops.
