Citrus Greening (CG) 
Disease Threat to Texas Citrus

Citrus greening disease, or Huanglongbing (HLB), is considered to be the most destructive disease of citrus. It is endemic in large parts of Asia and Africa, and has recently invaded the Americas. It is caused by a bacterium which is transmitted by insects called psyllids. There is no cure for greening, and the lengthy latent period after infection makes eradication almost impossible. The disease is now in Brazil, Cuba, Belize, southern Mexico and four US states (Florida, Louisiana. South Carolina, Georgia) - so far, it has not been detected in Texas, although the psyllid is widespread.

Thousands of crops have been lost citrus greening since it was first detected in 2005. Infected plants may not show symptoms for several months, so nationwide emphasis on early detection is being increased, including here in Texas. TDA has established this website containing more information.
