Citrus Greening
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.
What to Look For
The adult Asian citrus psyllid feeds with its head down; its abdomen and wings are erect at a 45-degree angle. Their larvae are tiny and yellow, often found on the underside of new, leafy growths.
If found, you can use mild, soapy water to spray on and kill them.
Tracking the Disease
