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.

  • Abstract: Chemical treatments were evaluated for efficacy against specific ant pests in two perennial field crop systems. A directed spray of Lorsban applied in grape vineyards resulted in significant reductions of Formica perpilosa Wheeler (Hymenoptera: Formicidae) for 9 wk. Significant reductions in the number of foraging Argentine ants, Linepithema humile (Mayr) (Hymenoptera: Formicidae), were obtained in citrus for the 4-mo duration of a test with a liquid bait delivery system containing either 0.0001% fipronil or thiamethoxam in 25% sucrose water.
