Chronic boron deficiency is believed to be caused by soil drying and high soil pH, while temporary deficiency is caused by heavy leaching. It results in a wide array of symptoms, not only among species of palms, but also within a single species. This 5-page fact sheet contains many illustrations to aid in diagnosis and management recommendations. Written by Timothy K. Broschat and published by the UF Department of Environmental Horticulture, June 2011.

Redbay Ambrosia Beetle Xyleborus glabratus Eichhoff (Insecta: Coleoptera: Curculionidae: Scolytinae) (EENY491/IN886)
Ambrosia beetles are wood-degrading insects that live in nutritional symbiosis with ambrosia fungi. Usually we consider ambrosia beetles beneficial because they accelerate the decay of dead trees, which is important for nutrient cycling in healthy forests. However, the redbay ambrosia beetle and its fungal symbiont transmit the causal pathogen of laurel wilt disease among plants in the Laurel family (Lauraceae). They are considered a “very high risk” invasive disease pest complex having potential equal to that of Dutch elm disease or chestnut blight. Laurel wilt is a relatively new disease and much is still unknown about how it will impact the flora of North America. This 7-page fact sheet highlights what we do know about this important new pest. Written by Rajinder Mann, Jiri Hulcr, Jorge Peña, and Lukasz Stelinski, and published by the UF Department of Entomology and Nematology, May 2011.

New Florida Foliage Plant Cultivar: Pothos ‘Pearls and Jade’ (ENH1180/EP441)
Pothos plants are tree-climbing vines native to the Solomon Islands, but they flower seldom and never under greenhouse conditions or in interior environments. As a result, no hybridized pothos cultivars are known to exist. Because of the barriers to hybridization, a program was initiated at the Mid-Florida Research and Education Center (MREC) in Apopka, Florida, to induce mutations in order to develop new pothos varieties. Pothos ‘Pearls and Jade’® (Fig.1) is a mutation selection from a group of ‘Marble Queen’ plants. This 4-page fact sheet describing the new hybrid was written by R. J. Henny, J. Chen, and T. A. Mellich, and published by the UF Department of Environmental Horticulture, March 2011.

Sudden Oak Death and Ramorum Blight (PP197/PP118)
Sudden oak death and ramorum blight are relatively new diseases capable of causing a range of symptoms, from leaf spots to plant death, on many woody hosts. Because these diseases are new, much about the pathogen, host range, and disease epidemiology is unknown. Currently, neither sudden oak death nor ramorum blight is established in Florida, but state agencies and university educators continue to work together to monitor for these diseases. This revised 4-page fact sheet describes the causal agent and gephgraphical distribution, host range, disease symptoms, and control options. Written by Phil Harmon and Carrie Harmon, and published by the UF Department of Plant Pathology, March 2011.
