Food diversity, nutritional food supply, and profitability are the priorities of agricultural and horticultural industries. To diversify vegetable products and increase the Florida vegetable industry's competitiveness, a number of new vegetable crops are rapidly emerging in the state. Due to Florida's favorable climate, these vegetable crops grow well and have high market potential. The objective of this 6-page fact sheet is to provide a general overview of long bean, one of the Asian vegetable crops grown in Florida.

Maximizing Weed Control in Florida Citrus
With Florida citrus growers and production managers being “squeezed” between rising production prices and declining yields from citrus greening, there’s more call than ever to reduce citrus production costs. Controlling weeds is a major expense, amounting to 11% of the total $2,278 annual production cost per acre for the 2014–2015 season. This 3-page fact sheet teaches the six essential components of an effective weed-management program to help maintain the profitability of this vital Florida industry. Written by Stephen H. Futch and Brent Sellers and published by the Horticultural Sciences Department. http://edis.ifas.ufl.edu/hs237
Mechanical Pruning of Citrus Trees
When citrus trees are not regularly pruned, less sunlight reaches the lower parts of the trees, which can reduce flowering and fruit development, quality, and color. Less sunlight also increases the risk of fungal infection. This 3-page fact sheets explains how growers can prune trees to maximize light exposure. Written by Mongi Zekri, and published by the UF Department of Horticultural Sciences, August 2015.

Resetting in Citrus Groves
To maintain the overall productivity of a citrus grove, dead or declining trees should be promptly removed and replaced with young, healthy trees, a practice known as resetting. Resetting presents many challenges for growers because young trees require more attention and care than more established trees. This 4-page fact sheet discusses effective resetting methods and maintenance for citrus. Written by Zekri Mongi, and published by the UF Department of Horticultural Sciences, August 2015.

Fungal Gummosis in Peach
Fungal gummosis in peach occurs when the fungus Botryosphaeria dothidea infects small openings or wounds in tree branches or trunks. The disease causes blisters on the tree that form lesions and eventually ooze gum (sap). This 3-page fact sheet covers the disease cycle and management of fungal gummosis in peach, which is often difficult to control.

The Good, the Bad, and the Ugly: What the Future Could Hold for Bs2 Tomatoes
Bs2 tomatoes are transgenic tomatoes that have been engineered to contain the Bs2 gene from pepper. As such, they are considered a genetically modified (GM) food, or a genetically modified organism (GMO). Numerous trials conducted by University of Florida researchers have shown the benefits of these cultivars for bacterial spot disease management, and growers and industry members recognize the potential for Bs2 tomatoes to make Florida tomato production more sustainable. This 4-page fact sheet discusses the benefits that might be realized by the adoption of Bs2 tomato varieties, and the challenges standing in the way of their commercial production. Written by S. F. Hutton, J. W. Scott, J. B. Jones, R. E. Stall, G. E. Vallad, B. J. Staskawicz, and D. M. Horvath , and published by the UF Department of Horticultural Sciences, April 2015.

Pepper is an important vegetable crop in Miami-Dade County. Unlike other vegetable crops, peppers are relatively more adaptable to the environment, especially the heat, and are relatively easier to grow. But to be successful, careful attention must be paid to maintain healthy plants and high productivity with efficient management of soil and water for the particular needs of each variety or cultivar. This 7-page fact sheet provides general information and guidelines for pepper growers in Miami-Dade County, including major pepper varieties, and their horticultural traits, and fundamental soil and water management requirements.

Control of Rapid Postharvest Decays of Tomato Fruit
What is a rapid postharvest decay? Water-soaked lesions begin within 12 to 18 hours after harvest and continue to develop, producing large amounts of fluids. The decay spreads within cartons of tomatoes, producing wet patches in the bottom and sides of the container, a condition called “wet-boxes.” Affected fruit are out-of-grade either prior to shipment or upon arrival at the receiver.This 5-page fact sheet was written by J. A. Bartz, S. A. Sargent, and D. J. Huber, and published by the UF Department of Horticultural Sciences, December 2014. (Photo: S. R. Bartz)

Techniques for Melon Grafting
Grafting as a cultural practice for controlling soilborne diseases and improving abiotic stress tolerance has been widely used in vegetable production in many areas of Asia and Europe. Interest in vegetable grafting has been growing in the United States in recent years, as well. Cost, along with the desire to customize scion cultivars and the need to produce organic transplants, has led many small and organic growers to choose to graft plants by themselves. To help growers who are interested in grafting melon plants achieve a high graft survival rate, this 5-page fact sheet introduces commonly used grafting techniques and their application in specific circumstances.

Hand Pollination of Tomato for Breeding and Seed Production
Hand pollination is a technique that is used for breeding new tomato varieties with desirable characteristics such as plant vigor, disease resistance, and uniform fruit quality and plant growth; since tomatoes have complete flowers and are self-pollinated, it usually is unnecessary to hand pollinate the flowers for fruit production. This 4-page guide illustrates selection and emasculation of flowers from the plant receiving pollen, pollen collection and drying, and pollination of the stigma.

New Sources of Southern Chinch Bug Resistance in St. Augustinegrass
Currently, Captiva is the only chinch bug-resistant variety of St. Augustinegrass grown on sod farms in Florida. But since these pests have previously overcome their resistance to Floratam, it is highly probable that they will do the same with Captiva in the future. It is also desirable to have resistant varieties available with different agronomic qualities such as shade tolerance or drought tolerance. This 4-page fact sheet reports the results of a preliminary screening to detect resistance to chinch bugs, conducted at the UF/IFAS Everglades research station on 36 untested St. Augustinegrass lines.

Converting from seepage irrigation to plasticulture for vegetable production: a case study and on-farm demonstration
Cabbage production in Florida has been dominated by the use of seepage or sub-irrigation, because it is inexpensive to maintain and simple to use, but it can require vast quantities of water to be pumped from the aquifer in low rainfall years. Plasticulture has been proposed as an alternative production method for cabbage production in Florida. An on-farm demonstration was setup on Greene’s Farms in Bunnell, FL to provide a platform for collaboration between researchers, growers and extension professionals. This 6-page fact sheet illustrates an innovative approach converting from seepage irrigation to plasticulture and points out some options and challenges for growers considering a plasticulture system. Written by Charles E. Barrett, Lincoln Zotarelli, Brian S. Taylor, Lucas G. Paranhos, and Mark Warren, and published by the UF Department of Horticultural Sciences, July 2014.
