Enterprise budgets are effective planning tools for growers in search of help with forecasting, resource coordination, and better production decisions. In essence, enterprise budgets can help ...producers determine what to produce, how many acres to produce, the cost of production, and the necessary price to be profitable. This 5-page fact sheet written by Tara Wade, Barbara Hyman, Eugene McAvoy, and John VanSickle and published by the UF/IFAS Food and Resource Economics Department describes the process used to create the 2017/18 enterprise budget for tomatoes in southwest Florida and includes resources for producers interested in creating enterprise budgets for their own operations.https://edis.ifas.ufl.edu/fe1087
Enterprise budgets can assist with forecasting as well as help managers coordinate resources, make production decisions, examine expenditures, and anticipate outcomes from changes in production ...practices. They can help producers determine what to produce, how many acres to produce, the cost of production, and the necessary price to be profitable. This 6-page fact sheet written by Tara Wade, Barbara Hyman, and Eugene McAvoy and published by the UF/IFAS Food and Resource Economics Department describes the process used to create the 2018-19 enterprise budget for bell peppers in southwest Florida.
Tobamoviruses are mechanically transmitted plant viruses that cause severe economic damage to vegetable and ornamental crops in Florida and worldwide. While certain tomato cultivars have genetic ...resistance to the most common tobamoviruses, no commercial tomato cultivars are resistant to tomato brown rugose fruit virus (ToBRFV), a recently described tobamovirus that also infects pepper and eggplant. It is currently unknown how ToBRFV may affect tomato production in Florida. This new 5-page publication of the UF/IFAS Plant Pathology Department describes symptoms of the virus, how it is different from other tobamoviruses, and how it is transmitted, as well as what to do if you think you have ToBRFV in your field.

On January 12, 2017 following a public comment period, the EPA announced its Policy to Mitigate the Acute Risk to Bees from Pesticide Products. This policy represents the EPA’s recommended labeling ...statements to mitigate acute risks to bees from pesticide products. This policy is not a regulation or an order and, therefore, does not legally compel changes to pesticide product registrations. This document outlines the highlights of the EPA policy.
Enriching environmental samples to increase the probability of detection has been standard practice throughout the history of microbiology. However, by its very nature, the process of enrichment ...creates a biased sample that may have unintended consequences for surveillance or resolving a pathogenic outbreak. With the advent of next-generation sequencing and metagenomic approaches, the possibility now exists to quantify enrichment bias at an unprecedented taxonomic breadth.
We investigated differences in taxonomic profiles of three enriched and unenriched tomato phyllosphere samples taken from three different tomato fields (n = 18). 16S rRNA gene meteganomes were created for each of the 18 samples using 454/Roche's pyrosequencing platform, resulting in a total of 165,259 sequences. Significantly different taxonomic profiles and abundances at a number of taxonomic levels were observed between the two treatments. Although as many as 28 putative Salmonella sequences were detected in enriched samples, there was no significant difference in the abundance of Salmonella between enriched and unenriched treatments.
Our results illustrate that the process of enriching greatly alters the taxonomic profile of an environmental sample beyond that of the target organism. We also found evidence suggesting that enrichment may not increase the probability of detecting a target. In conclusion, our results further emphasize the need to develop metagenomics as a validated culture independent method for pathogen detection.
Abstract
A total of 327 root samples collected from horticultural and agronomic crops,
and weeds associated with these crops in Florida crop production regions,
were examined. Isozyme phenotypes, ...esterase (EST) and malate dehydrogenase
(MDH) phenotypes were used to characterise and identify the species of
Meloidogyne present in these samples. At least 26 females from each sample
were examined using polyacrylamide gel electrophoresis. Sixteen major bands
of EST activity were found, corresponding to 12 phenotypes. A
species-specific EST phenotype was consistently associated with each of the
Meloidogyne spp. identified: Meloidogyne arenaria, M. floridensis, M.
graminicola, M. hapla, M. incognita, M. javanica, M. mayaguensis and M.
partityla. Two unique EST phenotypes, which have not been described, were
found associated with three unidentified nematode populations. Five bands of
MDH activity and four phenotypes were also found among the populations.
During this study, new host records were determined for M. floridensis and
M. mayaguensis, two recently reported Meloidogyne spp. in Florida. Plant
species found as new hosts of M. floridensis were Cucumis sativus, Phaseolus
sp., Solanum melongena and one weed species, Emilia sonchifolia, and the M.
incognita-resistant peach rootstock ‘Flordaguard’. New hosts for M.
mayaguensis were Carica papaya, Capsicum annuum var. Longum, and six weed
plants, including Eclipta prostrata, Fatoua villosa, Panicum sp., Poinsettia
cyathophora, Solanum americanum and also one unidentified weed species
belonging to the family Acanthaceae. To our knowledge, Florida is the only
geographic area of North America where M. floridensis and M. mayaguensis
have been detected.
This chapter covers production of cole crops and Asian crucifers, including broccoli, cabbage, cauliflower, Chinese broccoli, Chinese cabbage, Chinese mustard (bok choy), kohlrabi, lobok/daikon, ...collards, kale, mustard, and turnip.
