Dog sleuths sniff out crop disease hitting U.S. citrus trees

Dog detectives might be able to help save ailing citrus groves; research published Monday suggests. Scientists trained dogs to sniff out a crop disease called citrus greening that has hit orange, lemon and grapefruit orchards in Florida, California, and Texas. The dogs can detect it weeks to years before it shows up on tree leaves and roots. Dog sleuths are also faster, cheaper and more accurate than people collecting hundreds of leaves for lab analysis.
