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.

Protected Culture for Vegetable and Small Fruit Crops: The Soilless Trench System (HS1204)

Figure 5. Mature tomato crop growing in an SLS filled with pine barkVegetable and small fruit crop production under protective structures, such as greenhouses, high tunnels, and shade houses, often requires using soilless media to mitigate the impact of soilborne diseases, nematodes, and weeds, and it helps with management of fertilization and irrigation. Regardless of the nature and property of the media, they need to be held in containers to avoid direct contact with the soil or to elevate plants above the ground. An alternative to purchasing containers is building a soilless trench system for production of certain vegetables and small fruit crops. This 3-page fact sheet was written by Bielinski M. Santos and Teresa P. Salame-Donoso, and published by the UF Department of Horticultural Sciences, August 2012.

'Summer Pink': A New Pink, Fancy-Leaved Caladium Variety (ENH1200/EP461)

Figure 1. 'Summer Pink' plants produced by forcing de-eyed No. 1 tubers in 5-inch square containers.‘Summer Pink’ is a new fancy-leaved caladium variety developed by the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) caladium breeding program for use in large containers and shady locations in the landscape (Deng and Harbaugh 2012). Leaves of this variety have a pink face and pink veins. In replicated field and greenhouse trials, ‘Summer Pink’ performed comparably or better than ‘Fannie Munson’ and ‘White Queen’, two pink caladium varieties commonly used in containers and landscapes.

Entomopathogenic Nematodes (Nematoda: Rhabditida: families Steinernematidae and Heterorhabditidae) (EENY530/IN944)

Figure 3. Generalized life cycle of entomopathogenic nematodes.Entomopathogenic nematodes are soft bodied, non-segmented roundworms that are obligate or sometimes facultative parasites of insects. They occur naturally in soil environments and locate their host in response to carbon dioxide, vibration, and other chemical cues. They fit nicely into integrated pest management programs because they are nontoxic to humans, specific to their target pests, and can be applied with standard pesticide equipment.

Using Soils to Guide Fertilizer Recommendations for Southern Pines (CIR1230/FR053)

Figure 4. Example of copper (Cu) deficiency in young, loblolly pine growing on a CRIFF C group soil (note: the soft and s-shaped terminal and lateral shoots).Soils supporting southern pine stands in the South tend to be infertile and nutrient additions are often required to achieve optimum rates of production. This 12-page publication describes and classifies soils of the southeastern Coastal Plain region and specifically addresses issues of fertility, growth-limiting nutrients, and fertilizer recommendations for southern pines.

Potato Physiological Disorders – Internal Heat Necrosis (HS1145/HS395)

Figure 1. Internal heat necrosis symptoms in fresh market potato 'Red LaSoda'Internal heat necrosis is a physiological disorder that causes an unacceptable browning of the tuber tissue and can cause economic losses to the grower. The three leading suspected causes of IHN in tubers are high soil temperature, inadequate soil moisture, and suboptimal plant nutrition, or a combination of these factors.

Identification and Control of Johnsongrass, Vaseygrass, and Guinea Grass in Pastures (SSAGR363/AG372)

Johnsongrass is a common weed throughout the South and Midwest. People often incorrectly call any weed johnsongrass, but it is one of three grasses found in Florida pastures. Knowing the differences between johnsongrass, vaseygrass, and guinea grass will help with proper weed management. This 3-page fact sheet was written by H. Smith, J. Ferrell, and B.

Agricultural Management Options for Climate Variability and Change: Sod-Based Rotation (AE492)

A sod-based rotation is when a producer adapts a conventional peanut/cotton rotation by growing a perennial grass, such as bahiagrass, during two years of the rotation. The perennial grass can be grazed, cut for hay or harvested for seed for additional income. Using a sod-based rotation can improve soil water-holding capacity and potentially reduce impacts of dry spells and droughts.

Phosphorus Fertilizer Recommendations for Sugarcane Production on Florida Organic Soils (SSAGR348/SC091)

Much of the sugarcane grown in South Florida is on organic soils in the Everglades Agricultural Area, which is a phosphorus-limited system. Phosphorus loads in drainage water in the Everglades Agricultural Area are an environmental concern so it is important for sugarcane growers to use best management practices such as soil testing and to follow fertilizer recommendations. This document contains updated UF/IFAS phosphorus fertilizer recommendations for Florida organic soils. This 7-page fact sheet was written by J. Mabry McCray, Ronald W. Rice, and Alan L.

Postharvest Quality and Decay Incidence among Tomato Fruit as Affected by Weather and Cultural Practices. (PP294)

Figure 11. Concentric cracking of fruit surface.Postharvest decay losses for field-grown, fresh-market tomatoes are usually associated with harvests that occur when fields are wet and warm. During periods of persistently wet fields, decay pathogens infect damaged fruit on the plant as well as injuries to petioles and stems. Review of all reports and photos implicated excessive water in fruit rather than air temperatures as the primary predisposition. Excessive water in fruit is possible at virtually any time of the season and can appear at times of cold as well as warm field temperatures. This 8-page fact sheet was written by Jerry A. Bartz, Steven A. Sargent, and John W. Scott, and published by the UF Department of Plant Pathology, July 2012.

Identificacion de los sintomas del cancro citrico y procedimientos de descontaminacion (PP214SP/PP138)

Figure 1. Lesiones necróticas del cancro en los tallos, hojas y frutos de toronja.El cancro cítrico es una seria enfermedad de los cítricos. La mayoría de los cultivos de cítricos son susceptibles, la toronja, la lima mejicana y algunas naranjas tempranas son las más susceptibles. Una infección severa puede causar defoliación, una muerte regresiva de la rama, una decadencia general del árbol, una caída prematura de la fruta, y manchas en la misma. Los árboles severamente infectados se vuelven débiles, improductivos y no rentables.
