Chilling Injury in Tropical Foliage Plants: III. Dieffenbachia

A chilling temperature is any temperature that is cold enough to cause plant injury but not cold enough to freeze the plant. Chilling injury can occur to tropical foliage plants if greenhouses become too cold or if plants are exposed to chilling temperatures outside of the greenhouse during packing and shipping. Dieffenbachia, commonly known as dumb cane, ranks among the top five most popular foliage plant genera produced and sold in the United States. This four-page fact sheet describes the chilling temperatures of Dieffenbachia cultivars in order to assist growers to better manage greenhouse temperatures.

Creciendo Papas en el Jardín de su Hogar en la Florida

The Irish potato is a cool-season crop. A recently grown and harvested potato exhibits different flavor profiles from one that has been in storage or on a grocery shelf for an extended period. For example, in storage, the starches in potatoes convert to sugars, resulting in a less desirable texture and taste. “New” potato flavor can be achieved in the home garden by following a few growing recommendations. This is ten-page fact sheet is the Spanish language version of HS933 Growing Potatoes in the Florida Home Garden. Written by Christian T. Christensen, Joel Reyes-Cabrera, Lincoln Zotarelli, Wendy J. Dahl, Doug Gergela, Jeffery E. Pack, James M. White, and Chad M. Hutchinson.

Zika Vector Control for the Urban Pest Management Industry

Zika is a mosquito-transmitted virus that has recently spread to the Americas. Zika virus (ZIKV) was discovered in 1946 in Africa where it was isolated from a Rhesus monkey in the Zika forest of Uganda. In 2007, a disease outbreak occurred on the Yap islands in Micronesia, and in 2013, an outbreak occurred in French Polynesia. In 2015, a large outbreak occurred in Brazil, and ZIKV has since spread through the Americas. As of April 18, 2016, 15 counties in the state of Florida had reported travel-associated Zika cases. This seven-page fact sheet provides an overview of ZIKV, including its incidence and distribution, transmission and symptoms, and the connection between zika virus and infant microcephaly. This article also explains the biology and identification of the mosquito that vectors the virus with a focus on how to manage the vector using inspection, larviciding, adulticiding, monitoring, and personal protective equipment.

Pest Identification Guide: Chilli thrips Scirtothrips dorsalis Hood

Chilli thrips transmits the ilarvirus Tobacco streak virus (TSV) and the tospoviruses Groundnut bud necrosis virus (GBNV), Groundnut chlorotic fan-spot virus (GCSFV), and Groundnut yellow spot virus (GYSV). This species primarily feeds on young, tender foliage. Feeding on foliage may result in silvering leading to necrosis, leaf curl (upward), distortion, and defoliation. Feeding on the fruit may cause scarring, discoloration, and the formation of corky texture on the fruit. Learn to identify the chilli thrips with this two-page illustrated guide written by Jeffrey D. Cluever and Hugh A. Smith and published by the Department of Entomology and Nematology.

Metsulfuron-Methyl-Containing Herbicides Potentially Damaging Ornamentals when Applied to Turfgrass

Metsulfuron-methyl, also known as MSM, is an herbicide that is used to control broadleaf weeds and certain grass weeds. It provides effective control of some of the most problematic turfgrass weeds, such as wild garlic, Florida betony, dollar weed, and small Virginia buttonweed. Metsulfuron-methyl is absorbed by plant foliage, so if landscape plants come into contact with the spray or drift they can be injured. This four-page fact sheet describes the potential problems with metsulfuron herbicides, the areas most subsceptible to damage, how to diagnose injury, and how to reduce damage. Written by Chris Marble, Jason Smith, Timothy K. Broschat, Adam Black, Ed Gilman, and Celeste White and published by the School of Forest Resources and Conservation Department.

Pond Apple: A Tree Species Adapted to Salt Stresses

Soil salinity is a naturally ocurring problem for growers, gardeners, and homeowners in Florida. As sea-levels rise, seawater intrusion causes salt stress to plants grown in coastal lowland areas. This three-page fact sheet introduces a salt-tolerant species, pond apple (Annona glabra L.), which has great potential to be used in high-salinity coastal landscapes. Written by Guodong Liu, Yuncong Li, Kimberly Moore, and Kim Gabel and published by the Horticultural Sciences Department.

Consumer Perceptions of Lawn Fertilizer Brands

Widespread urbanization in the United States has increased the number of lawns. A healthy lawn provides many benefits, including urban heat dissipation, water quality protection, erosion control, carbon sequestration, community safety, aesthetics, and property value growth. Many homeowners maintain their healthy lawns by applying fertilizers throughout the growing season, but excess fertilizer runoff and leaching have received much attention recently because of waterway pollution and algae blooms, leading many states to place restrictions on what chemicals can be used in lawn fertilizers.

Consumers’ increased environmental awareness creates a niche opportunity for the fertilizer industry to promote environmentally friendly lawn fertilizers, but in order to effectively exploit it, industry stakeholders must understand consumer purchasing behavior before expending labor, time, and money creating products for sale. The following 3-page report written by Hayk Khachatryan, Alicia Rihn, and Michael Dukes and published by the Food and Resource Economics Department covers research methodology and the existing brand awareness and selection of consumers in the lawn fertilizer industry. It also discusses homeowners’ preferences for certain fertilizer attributes. Consumer awareness, selection, and attribute preferences indicate existing behavior, and understanding existing behavior assists in the development of effective marketing programs, promotional strategies, and policies.

Common Pines of Florida

Pine trees are highly important to Florida’s ecosystems and economy. There are seven species of native pines, and each grows best in a particular environment. People have found varied uses for each species as well. Several species are of commercial value and are cultivated and managed to provide useful products such as paper, industrial chemicals, and lumber. Some species are also managed to enhance wildlife habitat and to provide attractive landscapes. Of course, many pines grow naturally. Like any natural resource, pines may provide more benefits if they are managed wisely. This 11-page fact sheet written by Niels Proctor and Martha Monroe and published by the School of Forest Resources and Conservation gives an overview of the features and identification of the major pines found in Florida.
