What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

EFFICACY OF INSECTICIDES USED FOR GLASSY-WINGED SHARPSHOOTER CONTROL IN CITRUS NURSERY STOCK

  • Author(s): Grafton-Cardwell, Elizabeth; Campbell, Mark; Ouyang, Chris;
  • Abstract: Citrus nurseries located in glassy-winged sharpshooter (GWSS), Homalodisca coagulata, infested areas must ensure that the plants that they ship to uninfested areas of California are free of GWSS. Nurserymen accomplish this by treating the citrus trees with pesticides and by careful visual inspection of leaves for signs of GWSS prior to shipment. All stages of GWSS could potentially be transported. Experiments were conducted to determine the efficacy of various pesticides against adult GWSS and their ability to deposit eggs, and against the nymphs as they attempt to emerge from egg masses.
