Stay Current With Research on Rootstocks
By Jude Grosser The ultimate solution to the HLB problem is having good rootstocks that can mitigate or eliminate the disease’s impacts in any grafted commercial scion. With this, growers could profitably grow any scion, including grapefruit, Hamlin or even Murcott. Thus, rootstock breeding efforts focus on directly screening new rootstock hybrids for their ability to confer HLB tolerance or …
Deficit Irrigation Could Improve Fruit Quality in CUPS
By Fernando Alferez, Daniel Boakye, Susmita Gaire and Tim Gast Growing citrus under protective screen (CUPS) structures for fresh fruit production is effective in controlling HLB disease by completely excluding the Asian citrus psyllid (ACP, Diaphorina citri). After several years of research on CUPS to grow HLB-free trees in Florida, and with commercial growers increasingly adopting this technology, there is …
