Citrus industry urged to prevent psyllid movement

State and federal surveyors have not found additional psyllids in either case, he said.

Growers in quarantined areas have the option of removing all stems and leaves before leaving the area or treating with an approved insecticide and harvesting within seven days.

Blakely said he expected most growers will opt for sprays because of the labor involved in removing plant material.

“There’s going to be certain additional steps and cost involved with these additional sprays,” he said. “And there are scheduling issues, but it’s what needs to be done as far as trying to stop this pest.”

Many growers also will be looking at using insecticides allowed against psyllids when they treat for other pests in case psyllids are in groves at undetectable levels.

“Even if they haven’t seen the psyllid, it’s a precaution to keep populations from becoming established,” Blakely said.

Growers also are being encouraged to work with neighbors and take a coordinated approach to treatments. That way, psyllids can’t jump from a treated grove to an untreated grove to seek refuge.

“If they’re going to be spraying, it makes sense to talk to each other and time their sprays so they cover a large area at one time,” he said.

Citrus nurseries within the quarantine zones are prohibited from moving plant material to outside areas unless it comes from a U.S. Department of Agriculture-approved structure.

The quarantines will remain in place for two years, barring additional psyllid detections, Lyle said.
