New UF/IFAS Citrus Trial Data Available Soon
New research data are coming from trials of citrus rootstocks, scions and combinations of the two that University of Florida scientists hope will broaden the options of greening-tolerant citrus varieties available to commercial growers. Michael Rogers, director of the Citrus Research and Education Center (CREC), part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), said scientists …
Researchers to Study New HLB Treatment Method
University of California (UC) Davis research scientist Louise Ferguson is taking part in a $3.4 million project titled “Development of an automated delivery system for therapeutic materials to treat HLB-infected citrus.” The study is funded by the U.S. Department of Agriculture’s National Institute of Food and Agriculture. The four-year project includes work by researchers at the University of Florida, UC …

Opposite Production Situations This Season
By Marcos Fava Neves When compared to last season’s output, expected orange production this season is dramatically different in both Florida and Brazil. FLORIDA UP The U.S. Department of Agriculture’s November forecast for Florida’s 2018–19 orange crop is 77 million boxes, 71 percent more than last season’s 45 million boxes. Of these 77 million boxes of oranges, 32 million boxes …
Citrus Nutrition Day to Include Field Tours
This year’s Citrus Nutrition Day — at which growers will learn the latest data about growing the fruit, from the soil up through the plants — is expanding to include tours of field trials. After a morning of updates from University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers, participants may tour field sites at the Peace River …
Kaolin Clay May Be Viable Option to Protect Citrus Trees from ACP
Florida citrus growers have begun taking notice of kaolin clay, a powdery white compound, because it can cause Asian citrus psyllids (ACP) to “not take notice” of their groves. Long used to protect other fruit and vegetable crops, kaolin can also conceal citrus trees from hungry psyllids by confusing their visual sensory system, said Michael Rogers, director of the Citrus …
Vigilance Keeps HLB at Bay
By Len Wilcox California agriculture has long kept a watchful eye on the spread of HLB (huanglongbing or citrus greening disease). It’s a firestorm on the horizon, and the devastation the disease has wrought in Florida and other parts of the world has the full attention of California citrus growers. Working closely with industry leaders and grower groups, federal, state …
High-Density Plantings Could Boost Profits for Florida Citrus Growers
Florida citrus growers who plan to establish new groves might want to consider high-density planting, according to experts with the Citrus Research and Education Center (CREC) in Lake Alfred, part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Wider spacing between trees and rows was common decades ago but, with yields down and input costs up, …
UF/IFAS Event Combines Latest Citrus Varieties with New Breeding Research
On Dec. 4 at the Citrus Research and Education Center (CREC), citrus growers can see if they want to grow the latest varieties from University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) breeders and then learn more about commercializing crops. In the morning, industry members can sample the latest citrus varieties from UF/IFAS breeders. “These are new varieties …
Orange Imports Increase as Domestic Juice Supply Remains Squeezed
Until a solution for citrus greening is found, imports will be key to keeping Florida’s citrus industry afloat. Domestic orange production has been declining steadily over the last two decades, with citrus greening disease being the leading cause of decreased acres and productivity. As the gap between domestic production and consumption has widened, imports have increased to boost dwindling domestic …
Numerous ACP Found Near Visalia, California
A large population of Asian citrus psyllids (ACP) and nymphs were found in an older residential area northwest of Visalia, California, last week. With multiple life stages of ACP found, county and state officials have moved into eradication mode immediately. According to the Visalia Times-Delta, 250 ACP were found in four locations. California Citrus Mutual reported that up to 400 …
Components of a Healthy Citrus Soil
By Sarah Strauss and Ute Albrecht There is increasing discussion and interest in soil health from both growers and researchers. Soil health is generally synonymous with soil quality. It can impact not just sustainability, but also improve water-holding capacity, nutrient availability, yield and overall grove productivity. In citrus, soil health is particularly important because of the reduction of root mass …
Commissioner Putnam on the Citrus Crop Forecast
