The Washington Post recently published a “well-balanced article” about Florida’s citrus industry, telling its woes as well as progress against HLB, says Michael Rogers. “We hosted a reporter from the Washington Post back in July of this year,” says Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center. “I think …
Shortly before HLB was discovered in Florida in 2005, many trees on sour orange rootstock were lost to citrus tristeza virus (CTV), which is transmitted by the brown citrus aphid. Sour orange rootstock was extremely susceptible to CTV, so many growers stopped using the rootstock. “Switching to non-sour orange rootstock eliminated the danger from CTV decline,” University of Florida Institute …
