Citrus greening disease, or Huanglongbing (HLB), is deadly, incurable, and the most significant threat to the citrus industry. Most HLB research focuses on the tree canopy, but scientists in California studied the impact of HLB on root systems.

Avocado growers have one more thing to worry about, just recently things have settled with the polyphagous shot hole borer and have recently had a wakeup call about the Redbay ambrosia beetle(Xyleborus glabratus)that carries the deadly fungus, Laurel wilt (Raffaelea lauricola).
