HLB-Resistant Rootstock Deregulation Petition
If you grow citrus, Soil Culture Solutions asked USDA to determine that a genetically engineered Carrizo citrange rootstock called CarriCea should not be regulated under 7 CFR part 340. APHIS prepared a draft plant pest risk assessment that concluded CarriCea is unlikely to pose an increased plant pest risk compared to the nonmodified rootstock. APHIS is accepting public comments on the petition and draft PPRA through April 13, 2026, after which it will approve or deny the petition.
