Huanglongbing (HLB) is currently the most destructive disease of citrus worldwide. Although there is no immune cultivar, field tolerance to HLB within citrus and citrus relatives has been observed at the USDA Picos farm at Ft. Pierce, Florida, where plants have been exposed to a very high level of HLB pressure since 2006. In this study, we used RNA-Seq to evaluate expression differences between...

Oregon’s strawberry industry has more than a century history. Unfortunately, strawberry production has been declining drastically in the last two half decades due to declining price, rising cost of production and competition from California, Florida, Mexico and China. Most of Oregon’s strawberries were for processing markets. The combination of warm, dry days with cool nights optimizes color an...

The purpose of this research was to compare the overwinter survival of populations of Heterodera glycines at different latitudes in the United States and the effect of changing latitudes before and after the initiation of dormancy. Soil samples infested with H. glycines were collected in August or October in 1992 to 1994 from soybean fields in two to four states (combinations of Arkansas, Flori...

Warm-season grasses, also called C4, are the predominant forages for ruminant production in Florida. The C4 grasses grow well under high temperatures and generally cultivated between 25 N and 25 S of the equator. The C4 grasses are more efficient in fixing carbon dioxide than other grasses; however, they have a specialized thick-walled parenchyma bundle sheath around each vascular bundle, and m...

Internal contamination of Salmonella in plants is attracting increasing attention for food safety reasons. In this study, three different tomato cultivars "Florida Lanai", "Crown Jewel", "Ailsa Craig" and the transgenic line Sp5 of "Ailsa Craig" were inoculated with 1 µl GFP-labeled Salmonella Typhimurium through guttation droplets at concentrations of 10(9) or 10(7) CFU/ml. Survival of Salmone...

the rate and efficiency of decolorization of dyes likeblue ca, black b133, and corazol violet sr were tested to evaluate white rot fungal strains. trametes hirsuta and pleurotus florida showed the greatest extent ofdecolorization on nutrient salt media. maximum decolorization of 200 mg/l of blue 133 was obtained by 4days old incubated pleurotus florida followed bytrametes hirsuta after 6 days. ...

Florida citrus areas were affected by four severe hurricanes (three direct hits) within a 6-week period in August and September 2004. All segments of the Florida citrus industry were impacted either directly or indirectly. Citrus nurseries suffered extensive losses and bearing trees were uprooted, broken or lost leaves and fruit. Compared to the 2003-04 season, the orange crop was reduced by 31...

PRO-GEN® (arsanilic acid or P-G) has been shown to reduce acidity of Florida grapefruit as effectively as lead arsenate. A series of experiments in the 1987-88 citrus fruit sea son reconfirmed that P-G was effective for this use with con centrations of 600-1500 ppm. P-G is water soluble. However, deliberate attempts to wash it off immediately following spray application reduced its effectivenes...

Growing vegetables in controlled environments (CEs), such as hydroponics, aquaponics, and vertical structures, is a rapidly expanding industry Florida the United States, especially nearby urban areas. Although lettuce ( Lactuca sativa ) still mostly produced fields, growing CEs proximal to areas has become increasingly popular because it may facilitate reduced transportation time associated pos...
