UGA CAES team researching whiteflies statewide

By Clint Thompson, University of Georgia

Silverleaf whiteflies devastated Georgia’s cotton and fall vegetable crops last year. In response to this crisis, a team of University of Georgia College of Agricultural and Environmental Sciences research and UGA Cooperative Extension specialists is studying the pests statewide to help cotton and vegetable farmers avoid another year of disappointing crops.

“Teams are an important part of UGA. Many of the issues agriculturists face today require a collection of scientists from differing disciplines with differing expertise to address complex issues. The silverleaf whitefly fits the bill here,” said Phillip Roberts, UGA Extension cotton and soybean entomologist and Whitefly Team member. “Not only are whiteflies a direct pest of plants as a result of feeding, but they also transmit several viruses to vegetables that can have a devastating effect on virus-susceptible crops.” Continue reading

Whiteflies are a top priority being discussed at county production meetings

By Clint Thompson, University of Georgia

University of Georgia entomologists advise farmers to kill crops capable of hosting whiteflies after the crop is harvested a final time. Crops left in the field could continue to serve as hosts.

“The very best thing we can do right now is to minimize the amount of host material out there and starve these whiteflies to death during the winter,” UGA Cooperative Extension vegetable entomologist Stormy Sparks said. Continue reading

Pesticide resistant, crop threatening whiteflies found in Texas

by Adam Russell, Texas A&M AgriLife

A pesticide-resistant population of common plant-damaging whiteflies has been found in Texas, according to a Texas A&M AgriLife Extension Service specialist.

Whiteflies are sucking, insect pests similar to aphids, and damage ornamental and food plants, said Erfan Vafaie, AgriLife Extension program specialist in integrated pest management, Overton. Adults are winged while young whiteflies lie flat against leaves and can be difficult to see with the naked eye.  Continue reading

Cucurbit leaf crumple virus verified in south Georgia

In Southeast Farm Press

by Stormy Sparks and Bhabesh Dutta, University of Georgia

While we have all been bracing for the potential onslaught of silverleaf whiteflies, the one bright spot was that the viral diseases that caused the bigger disasters in 2016 had not been seen in 2017. This is no longer the case.

Cucurbit leaf crumple virus, which decimated snap beans and squash last fall, has been verified from squash in South Georgia (the week of Aug. 1). As with the whiteflies, this first occurrence is earlier than the disease was detected last year. This has also occurred at lower whitefly densities than last fall, which suggests the potential that a fair percentage of whiteflies may already be carrying the virus. Continue reading

Experts expect insect problems to get worse

in Southeast Farm Press

From whiteflies in southern Georgia to bollworms in North Carolina to plant bugs in Virginia, 2016 was a challenging insect year for cotton growers across the Southeast. Dominic Reisig is urging farmers to be prepared for another challenging year.

Reisig, North Carolina State University Extension entomologist, addressed “Emerging Insect Issues in the Southeast” at the annual meeting of the Southern Cotton Growers and Southeastern Cotton Ginners in Charlotte, N.C., Jan. 20, where he provided an insect situation, outlook report and control recommendations.

Georgia vegetable growers battling whiteflies this fall

by Kyle Dawson, University of Georgia

Whitefly populations in south Georgia have exploded over the past several weeks, troubling vegetable producers during the fall growing season, according to University of Georgia horticulturist Tim Coolong.

Coolong said growers must be up to date on spray programs, though combating whitefly populations of this magnitude will still be difficult. In some cases it might be impossible to to stop whiteflies before they spread viruses. Continue reading
