Cotton seedlings planted over a rye cover crop. After harvest, cotton fields are planted with a cover crop. Before cotton is planted the next season, the cover crop is killed and rolled , then the cotton seeds are planted using either a no-till or strip-till system. The resulting "mulch" provided by the cover crop residue provides insect habitat, moisture retention and some weed suppression. CAES News
Crop Ecology
The use of cover crops has risen among both traditional and organic producers for a variety of reasons — to control erosion, choke out weeds, improve soil health and enhance water availability. Now research by University of Georgia scientists is examining which cover crops also may provide important habitat for predatory insects that could help control disease- and damage-causing pests in cotton.

Spiders, Spiders Everywhere
Millions of palm-sized Joro spiders have suspended themselves in three-dimensional golden webs on porches, power lines and mailboxes in roughly 25 counties in the state — and counting. Although their numbers are a nuisance, the spiders are not considered a particularly harmful invasive species.
“To my knowledge, this is the all-time highest funding amount the UGA IPM program has received, which is incredible because this is a highly competitive national grant,” said Ash Sial, coordinator of UGA's integrated pest management program. CAES News
IPM Grant
An impressive team of University of Georgia researchers has received $765,000 from the U.S. Department of Agriculture’s National Institute of Food and Agriculture Crop Protection and Pest Management Program to support the continuation of integrated pest management (IPM) programming throughout the state over the next three years.

Pigskin and Peaches
Georgia and South Carolina share a border, a passion for football and pride in their peaches. With the University of Georgia and Clemson University campuses separated by a mere 70 miles, the Bulldogs and Tigers began fighting it out on the football field in 1897, with the teams set to meet for the 65th time on Sept. 4. As pitched as the battle is on the football field, there’s an even deeper rivalry between the two states when it comes to their peaches.
Like many other mosquito species, the larvae of Culex pipiens, commonly referred to as the common house mosquito, require certain vitamins to grow. These nutrients are extremely unstable in aquatic environments, and UGA researchers have found that gut microbes have to produce these components continuously in order for organisms like mosquito larvae to develop.

Mosquito Microbiota
To most people, mosquitoes are a nuisance. To University of Georgia entomologist Michael Strand, learning about their development processes could lead to new approaches in mosquito control.
The UGA cotton research team identified 24 Georgia counties where the presence of cotton leafroll dwarf virus (CLRDV) has been confirmed from commercial fields and UGA research farms during 2018-2019. CAES News
Cotton Leaf Roll Dwarf Virus
While aphids aren’t a direct threat to cotton plants, they can carry a persistent virus that is difficult to control and can cause significant losses in one of Georgia’s most important crops.
