By Ramdas Kanissery and Mahesh Bashyal Using compost and soil amendments is beneficial to Florida citrus groves. Florida soils are sandy and have a low organic matter and cation exchange capacity. Adding compost and organic amendments (e.g., humic acid) can enhance the soil’s ability to retain water and nutrients. These practices can also boost soil microbial activity and improve soil …
February’s federal citrus forecast trimmed another 2 million boxes from Florida’s projected orange crop, dropping expected 2022–23 production to 16 million boxes. That’s an 11% drop from what had already been projected to be a historically low orange crop. The forecast was issued by the U.S. Department of Agriculture National Agricultural Statistics Service (USDA NASS). If the Florida orange forecast …
By Larry Duncan and Fernando Alferez Newly planted citrus trees are far less tolerant of pests and diseases than when mature. Sting nematode (Belonolaimus longicaudatus) was not considered a serious economic threat to Florida citrus until successive hard freezes in the 1980s caused widespread replanting of groves. Patches of stunted, declining trees caused by the irregular distribution of sting nematodes …
The total Brazilian orange crop for marketing year 2022–23 is forecast at 405 million boxes (MB), a reduction of 10 MB compared to the previous season. The commercial area in the state of São Paulo and the western part of Minas Gerais should account for 305 MB, a drop of 3% from the prior year. Production from other states is …
California’s Citrus Pest and Disease Prevention Program (CPDPP) has developed a guide, Response for a Confirmed Huanglongbing Positive Detection in a Commercial Grove, to prepare growers for a finding of the disease. The guide is intended to educate growers about the California Department of Food and Agriculture’s (CDFA) huanglongbing action plan. The devastating citrus disease spread by the Asian citrus …
By Ramdas Kanissery Florida citrus growers face weed management problems throughout the year because of conditions that favor rapid weed growth in groves. A weed-free tree row is desired in a citrus grove to minimize weed competition with trees. Hence, chemical weed control using post-emergent, systemic herbicides like glyphosate has become a vital production practice in the Florida citrus industry. …
By Emilie Demard Mites are pests of economic importance in traditional groves and citrus under protective screen (CUPS). Results from a two-year survey in CUPS at the Indian River Research and Education Center (IRREC) in Fort Pierce, Florida, showed that the citrus rust mite and the citrus red mite populations can reach high levels resulting in leaf and fruit damage. …
By Ramdas Kanissery, Yiannis Ampatzidis, Mahesh Bashyal and Shea Teems Weed control is vital for profitable citrus production since weeds compete for nutrients and water, can harbor diseases and pests, and get in the way of equipment and workers. Without proper management, weeds lead to reduced crop yield and economic losses. Chemical weed control using herbicides is the most common …
By Ramdas Kanissery Hurricanes and the associated flooding will impact weed management in the affected season and the following years. Weeds should be effectively managed after these severe weather events as weeds may take advantage of the reduced competitiveness of recovering trees. INTENSIFY SCOUTINGA critical step in weed management after hurricanes is to scout groves and note the emergence of …
By Kirsten S. Pelz-Stelinski and Lukasz L. Stelinski Managing Asian citrus psyllids (ACP) remains a consideration for growers because psyllids transmit the citrus greening disease pathogen, Candidatus Liberibacter asiaticus (CLas), to newly planted trees. There are several tools that can reduce psyllid populations or mitigate the symptoms of HLB and improve the health of infected trees. However, additional methods that …
Entomopathogenic fungi have recently been seen attacking citrus whitefly and cloudywinged whitefly nymphs in North Florida citrus groves. Muhammad Shahid, Mujahid Hussain and Danielle Sprague, all with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), wrote about the “friendly” fungi in the October UF/IFAS Cold Hardy Citrus Connection newsletter. Shahid is a horticulturalist and Hussain is a …
By Homan Regmi, Larry Duncan and Johan Desaeger Two field trials were initiated in a Polk County, Florida, commercial grove of 15-month-old Valencia on Kuharske trees in 2019 to measure the effectiveness of integrated pest management (IPM) tactics for managing sting nematodes (Belonolaimus longicaudatus). Six chemical nematicides, many newly released, were compared in one trial. In the second, perennial peanut …
“Hurricane Ian has devastated much of Florida’s citrus industry,” said Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center. “The harsh reality is that the 2022–2023 season will be one of the most challenging that any of us has faced.” Several UF/IFAS Extension agents made early assessments of the …
A week before Hurricane Ian tore across Florida, Glenn Beck of Beck Bros. Citrus reported that there were hopeful signs for the coming season. Fruit in his better-looking groves were in the size range that tends to hold on trees until harvest. Beck, and his brother Mark, own and manage citrus groves across the state. He says each day since …
Alico, Inc. reported on Sept. 30 that initial observations following Hurricane Ian indicate there was significant drop of fruit in its groves. However, most trees remain intact. The magnitude of the fruit drop will be formally calculated by the company’s staff and insurance companies in coming weeks. Alico has 48,900 acres of citrus groves in Charlotte, Collier, DeSoto, Hardee, Hendry, …
