Amaranthus palmeri—Palmer Amaranth

First true leaves are roughly oval and have a slight notch or indentation at the end.

Palmer amaranth has become one of the most troublesome weeds in the southeastern US due to its vigorous growth rate, high seed production, and development of resistance to herbicides from multiple modes of action. This 4-page publication illustrates characteristics of this weed to assist in accurate identification, proper management, and development of effective control strategies. Written by Sergio Morichetti, Jason Ferrell, and Pratap Devkota, and published by the UF/IFAS Agronomy Department, revised April 2020.

This update to 2007’s second edition adds information regarding nutrition of Florida citrus trees affected by huanglongbing (HLB), also known as citrus greening. Much of the guidance provided in this document on nutrients, application methods, leaf and soil sampling, and irrigation scheduling is also effective for trees affected by HLB. However, research conducted since the previous edition was published has established changes in many production practices, including nutrient rates, irrigation scheduling, soil pH management, and use of Citrus Under Protective Screen (CUPS). Changes to the second edition will appear at the beginning of chapters 2, 6, 8, 9, and 11. See also this topic page for links to individual chapters in HTML and PDF formats. This 115-page book was edited by Kelly T. Morgan and Davie M. Kadyampakeni, and published by the UF/IFAS Department of Soil and Water Sciences.

Everglades Agricultural Area Soil Subsidence and Sustainability

Presence of calcium carbonate in the form o flimestone gets higher as the soils become shallow, raising the pH.

This 4-page major revision, a publication of the UF/IFAS Department of Soil and Water Sciences, highlights the current status of Histosols within the Everglades Agricultural Area in southern Florida. Over the last century, soils within the region have gradually been lost via oxidation, a process commonly referred to as soil subsidence. The rate of subsidence is gradually declining, due to factors such as increased mineral content in soil, humification, and water management (maintenance of higher water tables). Best Management Practices and crop rotation help slow down the rate of oxidation and promote soil sustainability within the region. Written by Jehangir H. Bhadha, Alan L. Wright, and George H. Snyder.

Smartirrigation Apps: Urban Turf

Smartirrigation Turf App

As freshwater resources become increasingly scarce, efficient irrigation scheduling methods that allow efficient irrigation water uses are required. Migliaccio et al. (2016) have developed an app called Smartirrigation Turf, an easy-to-use mobile tool that delivers information to improve irrigation scheduling for urban turf. The app was only available for Florida and Georgia, but recently, we have made improvements to the app and made it available to any location throughout the contiguous United States. The 7-page major revision, written by Haimanote K. Bayabil, K. W. Migliaccio, J. H. Debastiani Andreis, C. Fraisse, K. T. Morgan, and G. Vellidis, and published by the UF/IFAS Department of Agricultural and Biological Engineering, describes the changes made on the recently released Smartirrigation Turf app.

All pesticides are classified according to their toxicity, use pattern, and environmental effects. The two main classifications are unclassified use and restricted use, though unclassified pesticides are commonly referred to as general use pesticides. A restricted use pesticide is one that is for retail sale to and use by only certified applicators or persons under their direct supervision and only for those purposes covered by the applicator’s certification. This document will provide a listing of pesticide active ingredients registered in Florida that are classified as restricted and the reason(s) for the restricted use classification.

La Granada en Florida: Una fruta de arbol para Florida?

Árbol de granada ('Wonderful' cv.)

El potencial económico en la producción comercial para el cultivo de granadas en Florida es actualmente desconocido en este momento. La investigación científica continúa sobre la posibilidad de encontrar variedades de granadas que puedan crecer en Florida. Las condiciones ambientales, con una alta temporada húmeda en la Florida, y un clima caluroso, son factores que son favorables para las enfermedades en las granadas y eso reduce la calidad de esta fruta, especialmente para las variedades de temporada tardía como la variedad ‘Wonderful’. ‘Wonderful’ es el principal cultivar comercial que se originó en la Florida. Para reducir las enfermedades y evitar la competencia de comercialización con las granadas de California, la investigación para la producción de granadas en la Florida debe centrarse en buscar variedades de temporada temprana que puedan cosecharse en julio y agosto. This six-page document is the Spanish translation of HS44, The Pomegranate.

Protecting Perishable Foods During Transport by Truck and Rail

Airfoil accessories to increase fuel efficiency: underbody fairings

The importance of protecting perishable foods from loss of quality during transport has long been recognized. Increased recognition of the importance of the transport link in the food distribution cold chain in securing the safety of perishable foods has more recently become as well recognized.
This updated edition reflects the dynamic changes and innovations in the handling and transportation of perishable foods. Some of these include improved insulation and air movement, microprocessors for more efficient refrigeration, expert systems to control the transport environment and conserve fuel energy, and the use of telematics to monitor and control the performance of refrigerated vehicles during transit. This edition includes descriptions and recommendations for food transported over the road and by rail in marine containers, as well as in railcars. This 214-page revision was written by J. K. Brecht, Steven A. Sargent, Patrick E. Brecht, Jorge Saenz, and Leonard Rodowick and published by the UF/IFAS Horticultural Sciences Department in cooperation with the USDA AMS Transportation Services Division.
