Plant pathologist Megan Dewdney with the University of Florida Institute of Food and Agricultural Sciences discussed the basics of brown rot and its control at a recent disease seminar in Immokalee. Approximately 60 growers and others attended the seminar held at the Southwest Florida Research and Education Center. Brown rot is especially prevalent in early-season citrus varieties. “It’s particularly problematic …
Disease defense is on the agenda for the February 2019 issue of Citrus Industry. University of Florida plant pathologist Megan Dewdney gives growers a fungal foliar disease forecast for this year.

By Travis Chapin, Michelle Danyluk and Keith Schneider In preparation for implementing the Food Safety Modernization Act’s Produce Safety Rule (PSR), growers, harvesters and packers of fresh citrus are required to attend standardized food-safety training, such as the Produce Safety Alliance (PSA) grower training course, which outlines the minimum …
University of Florida Institute of Food and Agricultural Sciences researcher Xavier Martini recommends planting windbreaks on two or more sides of citrus groves. He gave this advice to growers at a recent Citrus Insect Management Workshop in Lake Alfred, Florida. Martini said windbreaks do a good job of keeping canker and HLB-spreading psyllids out of groves. The trees also help …
By Lauren Diepenbrock While Asian citrus psyllids (ACP) are an ongoing concern in Florida citrus due to their role in spreading the bacterium associated with citrus greening, they are not the only pest of concern to growers. Citrus leafminer (CLM) and root weevils are two pests that have been raising concerns and adding to the challenge of managing productive citrus …

At Citrus Expo, University of Florida soil scientist Kelly Morgan said nutrient uptake by HLB-infected trees can be improved by applying the proper amount of nutrition and managing pH. “Those two things go hand-in-hand,” he said. “As you reduce soil pH below 7, you increase the uptake of most nutrients. So we need to reduce our pH. Our pH has …
By Len Wilcox Early detection has become a vital line of defense in the California citrus grower’s war with huanglongbing (HLB) disease. Without careful monitoring, any tree in the grove can become a ticking time bomb that could lead to destruction of the entire orchard. The disease starts unnoticed. Many months can pass before a tree displays any visible evidence …

By Nate Jameson The decision-making process for choosing a scion/rootstock combination involves multiple factors. The process starts by answering the following questions: Question 1: New planting or resetting? If the block is being reset, is still profitable and will stay in production for several years, then I suggest the grower stay with the existing combination currently planted. If the block …
By Fred Gmitter, Ed Stover, Randy Driggers, Greg McCollum and Jude Grosser The U.S. Department of Agriculture (USDA) Agricultural Research Service citrus breeding program has a long history of releasing successful scion and rootstock cultivars. There had been a 15-year lapse in creating new hybrids, and the recently released cultivars largely reflect breeding efforts that preceded the onslaught of HLB …
From nutritional supplements to managing irrigation to grower outreach and education, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are finding additional ways to support Florida citrus growers in their fight against citrus greening disease. Twelve projects were funded by the state legislature-funded Citrus Initiative program in 2017-2018 that looked at possible short- and long-term solutions that …
