Florida Department of Agriculture and Consumer Services
The Division of Plant Industry is the regulatory agency within the Florida Department of Agriculture and Consumer Services that is responsible for protecting Florida’s native and commercially-grown plants from harmful pests and diseases. DPI also protects Florida’s apiary industry. Three bureaus are located at DPI headquarters in Gainesville – Plant and Apiary Inspection; Entomology, Nematology and Plant Pathology; and Method Development and Biological Control. The remaining two bureaus, Pest Eradication and Control, and Citrus Budwood Registration, are in Winter Haven. DPI also has one of the world’s largest arthropod collections, a museum that houses over 8.5 million pinned insects and non-insect arthropods, as well as special collections of bulk samples and vial samples in alcohol from around the world. These samples comprise a significant resource of an estimated 100 million specimens from many unique and disappearing habitats.

4823061 pitch canker Fusarium subglutinans Deodar weevil chip cocoon in sapwood. Pitch canker is vectored by adults feeding on shoots and boring into stem to lay eggs.
4824016 seedling blight of longleaf pine Ceratobasidium spp. A binucleate Rhizoctonia solani-like fungus. Similar to R. solani but with binucleate hyphal cells. Initial symptoms appear as water-soaking and chlorosis of needle bases.
4824020 Rhizoctonia damping-off, blight and rot Rhizoctonia solani Infection centers in beds
4824021 Rhizoctonia damping-off, blight and rot Rhizoctonia solani Infection center in bed.
4824022 Rhizoctonia damping-off, blight and rot Rhizoctonia solani Infections occur on seedlings in sandy soils as sand, washed by rain and irrigation ("sand splash"), accumulates at the base of the seedlings, creating a microenvironment of reduced aeration and increased relative humidity which favors infection.
4824023 Rhizoctonia damping-off, blight and rot Rhizoctonia solani Infections occur on seedlings in sandy soils as sand, washed by rain and irrigation ("sand splash"), accumulates at the base of the seedlings, creating a microenvironment of reduced aeration and increased relative humidity which favors infection.
