Management of Insect and Mite Resistance in Ornamental Crops (ENY843/IN715)

farm, flowers, field, crops, greenhouses. UF/IFAS File Photo.Resistance of arthropods to crop management chemicals has been problematic since the early era of synthetic organic pesticides. During the 1970s and early 1980s leafminer outbreaks heavily damaged herbaceous ornamental crops such as chrysanthemum, gypsophila, aster, and marigold in fields, shade houses and greenhouses. Several effective insecticides including organophosphates, carbamates, pyrethroids, and a triazine were identified for leafminer control during the outbreak; however, control was short-lived as the leafminer developed resistance to each insecticide.This 11-page fact sheet was written by James F. Price, Elzie McCord, Jr., and Curtis Nagle, and published by the UF Department of Entomology and Nematology, November 2012.

Alternatives to Synthetic Herbicides for Weed Management in Container Nurseries (ENH1203/EP464)

Figure 2. Gaps between the disk edge and container rim, along the installation slit, and around the plant stem allow weeds to grow. Weed management is one of the most critical and costly aspects of container nursery production. This is most effectively achieved through preventative practices, primarily with preemergent herbicides. But there are valid reasons for managing weeds with alternatives to synthetic herbicides, including sanitation, exclusion, prevention, hand weeding, mulching, and the use of cover crops, heat, and nonsynthetic herbicides.

UF-T3 and UF-T4: Two Sterile Lantana camara Varieties (ENH1202/EP463)

Figure 4. UF-T4 lantana flowers and inflorescences grown outdoors in ground beds in full sun. Lantana camara plants are valued for their bright flower color, butterfly attraction, tolerance to harsh environmental conditions, low maintenance requirements, and ease of propagation and production. But many existing varieties can be weedy or invasive when grown in tropical and subtropical regions. So in 2004, UF/IFAS started a program to develop sterile L. camara varieties with little to no invasive potential.
This 8-page fact sheet introduces the recently released UF-T3 and UF-T4 lantana varieties that have resulted from these breeding, selection, and testing efforts. Written by Zhanao Deng, David M. Czarnecki II, Sandra B. Wilson, Gary W. Knox, and Rosanna Freyre, and published by the UF Department of Environmental Horticulture, August 2012.

Fusarium Wilt of Canary Island Date Palm (PP215/PP139)

Figure 1. Overview of canopy of Canary Island date palm with Fusarium wilt. The black arrows point to leaves that are dying.As the name implies, Fusarium wilt of Canary Island date palm is primarily observed on the Canary Island date palm. It was first documented in the United States in the 1970s in California, but it was not documented in Florida until 1994. It now occurs throughout the state. The fungus obstructs the xylem (water-conducting) tissue, which results in desiccation and death. This 5-page fact sheet was written by Monica L. Elliott, and published by the UF Department of Plant Pathology, July 2012.

Bud Rot of Palm (PP220/PP144)

Figure 3. Bud rot of Cocos nucifera: no new leaves are emerging and crown is open-topped, while older leaves in canopy look healthy at this time.To understand bud rots, an explanation of palm anatomy is necessary. The growing point of the palm is often called the bud or heart. All leaves originate from there, and each palm stem has only one. Thus, when the bud is damaged or diseased, the palm usually dies. The first symptom is discoloration and wilting of the spear leaf and wilting/discoloration of the next youngest leaf. This 4-page fact sheet was written by Monica L. Elliott, and published by the UF Department of Plant Pathology, July 2012.

'Strawberry Star': A Spotted, Fancy-Leaved Caladium for Use in Containers and Landscapes (ENH1201/EP462)

Figure 1. 'Strawberry Star' caladium plants grown in ground beds in full sun'Strawberry Star' is a fancy-leaved variety with a primarily white leaf face and attractive red spots. It is similar to 'Marie Moir' in leaf color and coloration pattern but different from 'Marie Moir' in petiole color. Compared to 'Marie Moir', 'Strawberry Star' sprouts earlier, produces high-quality container plants, demonstrates better landscape performance, and yields more tubers. These improvements make 'Strawberry Star' a desirable replacement for 'Marie Moir' and an additional sun-tolerant variety for the landscape plant palette.

Professional Disease Management Guide for Ornamental Plants (PP202/PP123)

Bob McGovern, right, checks the roots of ornamental plants with plant breeder Brent Harbaugh. Photo Thomas WrightFlorida’s warm, humid environment is a gardener’s paradise and a great location for ornamental plant producers to grow numerous plant species — but these conditions also are suitable for the development of a wide variety of plant pathogens and insects that can spread them. Florida is also a major port of entry for the international trade of ornamental plants, which carries the risk of introducing exotic invasive pathogens, so growers are required to follow certain phytosanitory regulations. These challenges require growers to develop the most efficient production plans possible, incorporating as many tactics as they can to maximize plant health and minimize opportunities for pest and disease outbreaks—a concept known as integrated pest management (IPM). This 16-page fact sheet is intended to be used by growers, landscape professionals, and other pest control operators as a reference for managing ornamental plant diseases. Written by P. F. Harmon and S. D. Bledsoe, and published by the UF Department of Plant Pathology, June 2012.
