To increase nutrient and water use efficiencies and reduce nutrient leaching and environmental concerns, fertigation is recommended for commercial blueberry production. In fact, successful fertigation can enhance sustainability and maximize profitability for commercial blueberry enterprises. One of the key factors in fertigation is the correct calculation of fertilizer injection rate and time for the acreage. This publication helps blueberry growers correctly calculate fertigation injection rates and times and provides reference tables for checking injection rates and times needed for a variety of production scenarios.

Recommendations for Management of Whiteflies, Whitefly-transmitted viruses, and Insecticide Resistance for Production of Cucurbit Crops in Florida (EENY478/IN871)
Until recently, squash has been the only cucurbit crop seriously affected by the B biotype of the sweetpotato whitefly, also known as the silverleaf whitefly, because of the silverleaf disorder induced by feeding of the immature stages (nymphs). However, three viruses transmitted by the whitefly have been identified in watermelon, muskmelon, and squash in Florida since 2004, making whitefly management a priority for most cucurbits. This 8-page fact sheet details the current UF/IFAS recommendations for managing whitefly-transmitted viruses and for delaying the development of resistance to insecticides in the whitefly vector.

Cultural Practices for Vegetable and Small Fruit Crops: Using Kaolin Clay to Reduce Sprinkler Irrigation for Strawberry Transplant Establishment (HS1188)
Because of the current limitations on water usage for strawberry growers in the Plant City area of Hillsborough County, researchers at the UF/IFAS Gulf Coast Research and Education center have been looking for inexpensive ways to reduce the amount of sprinkler irrigation in strawberry production. This 3-page fact sheet presents research results on the effect of kaolin clay application on sprinkler irrigation volumes applied to newly transplanted strawberries. It was written by Bielinski M. Santos, Teresa P. Salame-Donoso, Craig D. Stanley, Alicia J. Whidden, Crystal A. Snodgrass, and Mary B. Henry, and published by the UF Department of Horticultural Sciences, December 2010.

AE452 Chill Accumulation Monitoring and Forecasting
AE452, a 6-page illustrated fact sheet by Clyde W. Fraisse and Alicia Whidden, introduces a new web-based tool for agricultural producers to track and forecast chill accumulation during the winter season to reduce risks associated with climate variability in the southeastern U.S.A.

HS1156 Review of Nutrient Management Systems for Florida Vegetable Producers
HS1156, a 17-page white paper from the UF/IFAS Vegetable Fertilizer Task Force, identifies differences between actual fertilization practices and UF/IFAS fertilizer recommendations, especially for vegetables grown with subsurface (Central and South Florida) and overhead (Miami-Dade County) irrigation. The recommendations of the VFTF aim at bridging the gaps between science-based results and the diversity in production systems found in the Florida vegetable industry. Includes references. Published by the UF Department of Horticultural Sciences, April 2009.

HS1134/HS385 Characterization of the “Strawberry Dried Calyx Disorder” in Florida and Spain
HS-1134, a 3-page illustrated fact sheet by Bielinski M. Santos, Craig K. Chandler, Alicia J. Whidden, and María del Carmen Sánchez, presents the results of surveys and tests conducted into the nature of this disorder (SDCD) observed in strawberries since 2005 in farms around Plant City Florida and Huelva, Spain. Published by the UF Department of Horticultural Sciences, February 2008.
