Sugarcane Cultivars Descriptive Fact Sheet: CPCL 97-2730 and CPCL 00-4111

CPCL 00-4111 at late growth in muck soil.

CPCL 97-2730 and CPCL 00-4111 are emerging sugarcane cultivars in Florida with rapid expansion in last couple of years. Both were ranked among the top 10 sugarcane cultivars in Florida in the 2015 Sugarcane Variety Census (VanWeelden et al. 2016) based on their total acreage. High biomass yield and better rust resistance greatly improve the chances of the cultivars? adoption by growers. This fact sheet provides basic information and yield and disease information about CPCL 97-2730 and CPCL 00-4111 to assist growers in decision-making related to further expansion of these cultivars.

An analysis was conducted using the Implan regional economic modeling system and associated state and county databases (IMPLAN Group LLC) to estimate economic multipliers and contributions for over 500 different industry sectors. Multipliers capture the indirect and induced economic activity generated by re-spending of income or sales revenues in a regional economy. A collection of 121 industry sectors were included in the analysis to represent the broad array of activities encompassed by agricultural and natural-resource commodity production, manufacturing, distribution and supporting services in Florida. Economic contributions can be measured in terms of employment, industry output, value added, exports, labor income, other property income, and business taxes. This three-page summary was written by Alan W. Hodges, Mohammad Rahmani, and Christa D. Court and published by the UF/IFAS Food and Resource Economics Department.

Regenerated Sabal/Cabbage Palms (Sabal palmetto): Why and How

Sabal palms are held on a rack for six weeks.Palms are woody monocots characterized by the production of adventitious roots from the base of the trunk. Unlike the woody roots of dicots, such as oaks, gumbo limbo, and sea grapes, palm roots have no secondary thickening. Also, unlike trees, palms are incapable of repairing damage to their trunks. Most importantly, the life of a palm is dependent upon the continued good health of the single growing bud known as the meristem. Thus, if the palm bud is killed, the entire palm or the palm cane will eventually die. This 4-page fact sheet discusses harvesting and transplanting sabal palms, cropped transplants, and regenerated transplants. Written by Stephen H. Brown and Tim Broschat, and published by the UF/IFAS Environmental Horticulture Department, September 2017.

Citrus Production Guide: Rootstock and Scion Selection

Oranges on trees in a grove at the Citrus Research and Education Center. Photo taken on 03/04/16.When preparing for replanting, an important factor to consider is the choice of rootstock. Choosing the right rootstock and scion combination can result in higher economic returns without any additional cost. Rootstocks affect scion vigor, yield, fruit size, juice quality, and pest tolerance. However, tree growth, yield, and fruit quality interact strongly with climate, soil type, tree spacing, and other factors, often producing contradictory reports on rootstock performance in different areas. This 3-page fact sheet discusses soil characteristics, rootstock effects on pests and diseases, tree spacing and size, and rootstock/scion combination. Written by Ute Albrecht, Fernando Alferez, and Mongi Zekri, and published by the UF/IFAS Department of Horticultural Sciences, September 2017.

Citrus Irrigation Management

A farmer operating an IFAS-developed mobile app to control citrus irrigation.The chapter on irrigation management of citrus is largely taken from guidelines provided in SL253 on trees prior to Huanglongbing (HLB) prevalent conditions. A section has been added to cover recent findings on water use of trees affected by HLB and the impact this would have on the irrigation management considerations. This 6-page fact sheet discusses water supply, allowable soil water depletion, irrigation scheduling, soil moisture measurement, water budgeting, smartphone apps, irrigation strategies to improve nutrient uptake and reduce leaching, and irrigation management considerations for HLB-affected trees.

Soil Testing and Interpretation for Florida Turfgrasses

John Cisar, a professor of Environmental Horticulture at the University of Florida's Fort Lauderdale Research and Education Center, is studying how turfgrass and other landscape plants can help prevent nitrogen from leaching through the soil into groundwater, Wednesday - Aug. 13, 2003. He said three years of research have shown that turfgrass is most effective in reducing nitrogen leaching and should be used in Florida landscapes. Other plants require more time to become established and slow nitrogen leaching through the soil.
Most people agree that healthy, well-maintained turfgrass is a thing of beauty. The successful growth of turfgrass is aided by having knowledge of a few basic facts concerning the nutritional requirements of turfgrasses and the properties of fertilizer and liming materials. This four-page document will help the reader understand how soil testing may be used to more efficiently manage nutrient applications for Florida turfgrasses. Written by T.W. Shaddox and J.B. Sartain and published by the UF/IFAS Department of Soil and Water Sciences, October 2017.

2017-2018 Florida Citrus Production Guide: Fresh Fruit Pesticide Residue Limits


Current citrus production practices often include the use of various chemicals, many of which are pesticides. Chemical residues on the fruit after harvest are a concern to regulators and the public alike because of their potential negative health effects. Therefore, the US and other countries set maximum residue limits (MRLs) on fresh produce for various chemicals. This five-page document is part of the 2017-2018 Florida Citrus Production Guide and discusses the MRLs for various chemicals used on Florida citrus. Written by Mark Ritenour and published by UF’s Horticultural Sciences Department, October 2017.

Microirrigation is an important component of citrus production systems in Florida. For citrus trees, microirrigation is more desirable than other irrigation methods for several reasons: water conservation, fertilizer management efficiency, and freeze protection. Research has shown that when microirrigation systems are properly managed, water savings can amount to as much as 80% compared with subirrigation and 50% compared with overhead sprinkler irrigation. Research has also shown the important advantage of microsprinklers for freeze protection of citrus. This 4-page fact sheet discusses fertilizer solubility and some common fertigation materials. It also offers a fertigation summary.

Cane toad (Bufo marinus)

Cane toads are an invasive species in Florida and in many countries around the world. They have been established in Florida since the 1950s. Cane toads are larger and more poisonous than Florida’s native toads; they can be fatal to dogs that try to eat them, and they may be harmful to Florida’s native species. Discover the history of cane toads in Florida and learn to distinguish them from native toads. Find out the impacts they can have on both ecosystems and people, and get tips on how to deal with them in yards and neighborhoods in this 6-page publication written by Steve Johnson and Audrey Wilson and published by the Wildlife Ecology and Conservation Department.

What Is the ENSO Climatology Tool?

Storm rising over a farm.On a global scale, periodic anomalies in sea surface temperatures coupled with shifts in atmospheric pressure and winds, such as those associated with the El Niño Southern Oscillation (ENSO), can have profound impacts on weather conditions. ENSO affects atmospheric circulation patterns well into the midlatitudes and is the leading driver of seasonal climate variability in the United States. Tremendous advances have been made in predicting the occurrence of ENSO events with confidence three to six months in advance. This 5-page fact sheet discusses the ENSO climatology tool as well as possible challenges. Written by Caroline Staub, Clyde Fraisse, Eduardo Gelcer, and Daniel Dourte, and published by the UF Department of Agricultural and Biological Engineering, March 2017.
