This field guide is based on a 2-year study of ground-dwelling spiders in blueberry farms in southeastern Georgia and shows the most common spider families and genera found. This guide is for farmers, students, and educators to help them recognize these groups. Spiders are helpful organisms that feed on insects and other small creatures. In many cases, they are among the most effective natural controls of pest insects in gardens, farms, forests, and even inside homes.

Exobasidium leaf and fruit spot, caused by the fungus Exobasidium maculosum, is an emerging disease affecting both southern highbush and rabbiteye blueberries. In addition to direct yield loss due to fruit drop, lesions on remaining fruit compromise the aesthetic qualities of the fruit as well as the taste, rendering them unmarketable. This circular provides the most current knowledge of this important pathogen/disease of blueberry and its management.

The southeastern blueberry bee is an economically valuable pollinator in commercial blueberry production in Georgia. Researchers see a need for conservation of this species, and this resource provides detailed information on its identification, biology, nesting habitat, and floral hosts. It also incorporates research data from recent study in commercial blueberry system in south Georgia.

Blueberry gall midge, a small fly native to North America, has emerged as one of the serious pests of blueberries in Georgia. Severe gall midge infestations can cause up to 80% crop loss without proper intervention. Bud sampling to monitor for larvae is the only way to confirm its presence. Insecticide sprays need to be timed to target adult midges before they have a chance to lay eggs.
