Avocado trees are a popular choice for homeowners in Florida, with over 600,000 growing in Florida home landscapes. However, avocado trees as well as others in the Lauraceae family are susceptible to laurel wilt disease, which can kill a tree in as few as three weeks. This new 7-page publication of the UF/IFAS Horticultural Sciences Department provides home owners recommendations for identifying and mitigating laurel wilt disease in the home landscape. Written by Jonathan H. Crane, Jeff Wasielewski, Daniel Carrillo, Romina Gazis, Bruce Schaffer, Fredy Ballen, and Edwards Evans.
Dragon fruit, also known as pitahaya, pitaya, and strawberry pear, is a group of vine-like, climbing cacti. In south Florida, production of dragon fruit has been steadily increasing since the 2000s, and growers in Florida consider dragon fruit as a potential alternative fruit crop to avocado and citrus, two economically important fruit crops largely impacted by laurel wilt and huanglongbing, respectively. This new 4-page article focuses on the symptomology and epidemiology of stem and fruit canker, a prevailing disease on dragon fruit. Suggested management strategies for the disease are also discussed based on recent studies conducted in south Florida. Written by Cheng-Fang Hong, Shouan Zhang, Romina Gazis, Jonathan H. Crane, and Jeff Wasielewski, and published by the UF/IFAS Plant Pathology Department.

Agriculture is an important contributor to Florida’s economy. Only the tourism industry employs more Floridians. In 2012, agricultural output was estimated at $141.8 billion, accounting for 14.9% of the state’s gross domestic product, and providing employment for 20.8% of the state’s labor force. Monitoring the performance of the sector over time is therefore of critical importance to various stakeholders. This 8-page publication written by Edward Evans and published by the Food and Resource Economics Department focuses on the Agricultural Census data for Miami-Dade County and specifically examines trends over the 15-year period from 1997 to 2012 with the aim of highlighting some of the major trends occurring in the Miami-Dade County agricultural sector. In general, the data show that in spite of challenging times, the agricultural industry has remained important, contributing $604 million to the Florida economy in 2012.
The white Thai guava variety, which is very popular in the Asian market, is beginning to expand into mainstream markets. It has quick, high yields, is easily propagated and is tolerant to moisture stress and soil salinity.

This 7-page fact sheet identifies inputs, costs, and yields considered to be typical of a well-managed five-acre Thai guava orchard in south Florida. Written by Stella Garcia, Edward A. Evans, and Jonathan Crane and published by the UF Department of Food and Resource Economics, August 2016.
