In addition to weather information accessible in multiple databases, there …
By Matt Smith It’s September in Florida, which means two things: the start to the latest “rebuilding year” for Florida football and the traditional peak of hurricane season. It was in September of 2017 that Hurricane Irma cut just about the worst path imaginable for Florida’s citrus growers. Along with causing physical damage to groves, Irma also contributed to disease …
On Aug. 4, the National Oceanic and Atmospheric Administration (NOAA) slightly decreased the likelihood of an above-normal Atlantic hurricane season to 60%. That is down from 65% in the initial NOAA outlook issued in May. The likelihood of near-normal activity has risen to 30% from 25% in May, and the chances remain at 10% for a below-normal season. NOAA’s update …
On Aug. 4, Colorado State University (CSU) decreased its hurricane forecast for Atlantic seasonal activity and landfall strike probability for 2022. But citrus growers and other agriculturists shouldn’t relax their guard because the CSU Department of Atmospheric Science continues to call for an above-average Atlantic hurricane season. NEW PROJECTIONSCSU now forecasts the Atlantic will have 18 named storms in 2022, …
This summer has been a steamy one with some Florida locations breaking record highs. The latest episode of the All In For Citrus podcast took up the hot topic with Amir Rezazadeh, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) fruit and field crops Extension agent. He addressed how heat can affect citrus trees and people working …
By Anirban Guha Heat stress could take a toll on citrus tree health and fruit yield. In Florida, the hot season lasts more than four months. Long, hot, oppressive summer days can heat up leaves and fruit and make the trees extra thirsty. Also, high soil evaporation, irregular rainfall and poor soil water-holding capacity can often lead to summer drought …
By Amir Rezazadeh Heat stress happens when the body is exposed to extreme heat in a hot environment. Heat-related illnesses include heat stroke, heat exhaustion, heat cramps and heat rashes. Other signs of heat stress include sweaty palms, fogged-up safety glasses and dizziness. Agricultural workers are at risk of heat stress. Those who are 65 years of age or older, …
Colorado State University (CSU) hurricane researchers on June 2 increased the number of named storms and hurricanes they expect for the 2022 Atlantic hurricane season from their initial outlook in April. The CSU Tropical Meteorology Project team is predicting 20 named storms in 2022. Of those, researchers expect 10 to become hurricanes and five to reach major hurricane strength (Saffir/Simpson …
Forecasters at the National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Center, a division of the National Weather Service, are predicting above-average hurricane activity this year. The Atlantic hurricane season runs from June 1 to Nov. 30. This year could be the seventh consecutive above-average hurricane season. NOAA predicts a 65% chance of an above-normal Atlantic hurricane season, a 25% …
A prolonged dry spell across the Southeast should have citrus growers ensuring their young trees are properly irrigated. But Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, cautions growers about applying too much water. “The real young trees don’t have much of a root system, of course. It has been pretty dry. But you don’t want …
By Anirban Guha and Christopher Vincent A quick body temperature test is common these days before entering many workplaces, hospitals and clinics due to the ongoing COVID-19 pandemic. The purpose is to screen people for fevers, usually with a non-contact infrared thermometer. Measurement of plant body temperatures also has become common for many field crops, not to screen for infectious …
Hot and dry conditions are being seen in citrus groves across the Southeast. Growers are reminded to keep their trees — young and old — supplied with an ample amount of water. Citrus grower Kim Jones, who owns a citrus packing facility in Monticello, Florida, and is part-owner of a similar facility in Tifton, Georgia, discusses the importance of keeping …
“The local market has improved since last season,” says citrus grower Chip Henry. “I’ve gained customers, and existing ones are buying more. When people know the fruit is being harvested, they seek out that local supply and want to support their local farmers.” Henry grows 12 acres of organic Valencias at McGuire Groves in Apopka, Florida, and sells his fruit …

Weather affects what pests you might be spraying for and the worker doing the spraying. There are environmental safety risks …
It often takes time for the damage associated with freeze events to manifest in citrus. That was the case for the late January freeze in Florida. While some growers escaped fairly unscathed, others suffered significant damage. The damage began to show in the U.S. Department of Agriculture’s March citrus crop forecast. The agency lowered expected production of Florida oranges this …
Citrus black spot (CBS) disease has only been found in five Southwest Florida counties, but that could change as a result of 2017’s Hurricane Irma, a researcher reiterated recently. University of Florida Institute of Food and Agricultural Sciences plant pathologist Megan Dewdney, in a Feb. 24 presentation, said “Irma will haunt us for a while.” She explained that Irma likely …
By Megan M. Dewdney Postbloom fruit drop (PFD) is a flower disease mainly caused by the fungus Colletotrichum acutatum. The fungus is present on citrus trees throughout the year but survives by producing resting structures on leaves and stems. The fungus becomes stimulated to produce spores by substances from the early flowers. These early spores infect the initial flowers and …
The Florida Department of Economic Opportunity (DEO) on Feb. 3 activated the Business Damage Assessment Survey to assess the impact freezing temperatures had on the state’s agriculture businesses. Survey responses will allow the state to gather data and evaluate resources that impacted businesses may need to recover after the freezing weather that occurred the weekend of Jan. 28–30. “The agriculture …
Florida Gov. Ron DeSantis on Feb. 2 issued an executive order declaring a state of emergency in many counties where citrus and other agricultural commodities were affected by a Jan. 28–30 freeze.
