What do you all think the impact to HLB will be due to the extreme cold? Most of my citrus trees were killed (Hoping my kumquats made it). My thoughts are that the asian psyllid population likely took a significant hit. Also, I had noticed several large citrus trees around here with HLB symptoms (I just took down my 8 year old rio red grapefruit that was diagnosed with it). With so many citrus trees having been killed in the area, the limited sources of infection could give existing/new trees a breather. That's my gloomy silver lining from having lost so many trees (12, if you don't count my kumquats).
Also, if a tree had HLB and was killed down to the rootstock, presumable any regrowth from the rootstock is infected, correct?
