The cotton jassid, also known as the two-spot cotton leafhopper, has been problematic for cotton and vegetable growers across the Southeast. According to the South Florida Pest and Disease Hotline, the jassid is impacting growers in southern Florida.
Scouts are reporting the insect’s presence in Southwest Florida, with population levels ranging from low to high on eggplant. Population levels are increasing in certain locations, though no visible damage was reported.
The insect was observed on eggplants along the east coast as well. Population levels remain high in summer okra fields in Homestead, Florida. A few leafhoppers were reported on tomato and eggplant near okra plantings but no damage on the crops since they are being sprayed more frequently.
Dak Seal, entomologist at University of Florida Institute of Food and Agricultural Sciences Tropical Research and Education Center, reports the insect on old okra plantings at high levels; on eggplant at medium levels; and on bean occasionally.
Scouts are encouraged to monitor the jassid on okra, eggplants, cucurbits, peppers and beans.
