By Davie Kadyampakeni, Sandra M. Guzmán and Ajia Paolillo Using soil moisture sensors for irrigation scheduling can reduce water stress in citrus trees. Sensors that are easy to calibrate and maintain, specifically designed for managing irrigation and fertigation on Florida’s sandy soils, are the preferred choice. These tools enable growers to use their water resources wisely and efficiently. There are …
The Fundecitrus app, launched in February, has a new feature to help citrus growers properly rotate insecticides to manage the psyllid that spreads citrus greening disease. The new feature helps growers choose insecticides with different modes of action. The use of insecticides with the same mode of action in sequential applications can result in an increase in the frequency of …
Using drones to apply chemical control for HLB-spreading psyllids in Brazil proved effective against adult insects, a Fundecitrus researcher reported. The researcher, Marcelo Miranda, said psyllid mortality was above 80% as a result of drone applications. Miranda’s work was pioneering in 2021. There was no record of the use of drones for the chemical control of the psyllid in western …
By Amit Levy and Tripti Vashisth Many Florida citrus growers are currently injecting oxytetracycline, spraying gibberellic acid (GA) or treating trees with enhanced nutrition. A new program offered by the University of Florida Institute of Food and Agricultural Sciences (UFIFAS) Citrus Research and Education Center (CREC) can help growers determine if these treatments are improving tree health and leading to …
Far from his roots in a small town in northwest China, Changying “Charlie” Li is now the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) artificial intelligence (AI) administrative coordinator. He’s also a professor of agricultural and biological engineering. Li joined UF/IFAS last year to focus on agricultural AI with research, teaching and administration appointments. He wants to …
Tripti Vashisth, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor, joined the March episode of the All In For Citrus podcast to discuss a new smartphone application growers will be able to use soon to measure tree health. Plant growth regulators like gibberellic acid, 2,4-D and brassinosteroids have demonstrated the ability to improve tree health and …
Technological advancements in recent years allow drones to perform precise agricultural work efficiently. One of the tasks in greatest demand is the application of phytosanitary products in a quick and timely manner. Drones can be used for extensive applications in a short time and are ideal for ultra-low-volume interventions. With drones, very specific sectors, such as sources of disease or …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) breeders produce new citrus plants more quickly than they can figure out if consumers like how the new fruit varieties taste. In the race to create versus evaluate, creators lead evaluators by hundreds of individual plants at a time. It takes a post-doc a …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers plan to use artificial intelligence (AI) technology to quantify damage to fruits and vegetables caused by extreme weather events. One such extreme weather event was Hurricane Ian, which struck Florida on Sept. 28, 2022. The storm’s damage to all crops, livestock and aquaculture products was initially estimated at up …
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 …
While irrigation and technology were meant to be the focus of the November issue of Citrus Industry, the aftermath of Hurricane Ian, combined with the low initial crop forecast that does not even account for the storm’s damage, proved to be the much bigger story. Editor-in-Chief Frank Giles provides early details on the hurricane’s damage to Florida’s citrus industry and …
Fresh-tasting satsuma orange juice with a commercially feasible shelf life is the goal of University of Georgia (UGA) Food Product Innovation and Commercialization Center (FoodPIC) scientists and food technology company Food Physics. FoodPIC and Food Physics are working together to perfect a technique known as pulsed electric field technology (PEF). PEF uses short bursts of high voltage —15,000 volts per …
By Yiannis Ampatzidis and Sandra M. Guzmán Pests and diseases, nutrient deficiencies, tree stress from environmental conditions and other factors can be overwhelming. The arrival of sensors and small unmanned aerial vehicles (UAVs) make it possible to gather large amounts of data to assess risk factors and estimate possible crop performance scenarios based on the availability of resources. At the …
Two University of Florida (UF) startup companies have formed a union to help reverse the trend of declining Florida citrus production. Agriculture Intelligence and Satlantis believe they can offer a powerful tool to help the state’s growers more closely monitor their trees and manage problems faster. The startups, housed in one of UF’s business incubators, will combine expertise in precision …
While sending citrus tissue samples to the lab for analysis remains important, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has developed a smartphone application (app) that can supplement lab analysis to identify leaf symptoms of key nutrient deficiencies and certain pests and diseases. Arnold Schumann, a professor of soil and water science with UF/IFAS, demonstrated how …
The use of a drone for chemical control of the psyllid that spreads HLB adds to Brazil’s efforts to battle the citrus disease, recent research indicates. The research was conducted by Fundecitrus in partnership with the startup Anáhata Serviços Agronômicos. Drones are ideal for complementing terrestrial applications and for emergency applications that need to be made quickly. For example, a …
University scientists, engineers, producers, government agencies and industry officials across the Southeast recently met to brainstorm ways to use artificial intelligence (AI) to help growers. They concluded that they could empower growers and equip farms to increase their economic and environmental sustainability and develop resilient solutions to address climate change by using AI. The three-day conference, Envisioning 2050 in the …
There was a truck driver shortage before COVID-19, but the pandemic certainly compounded the problem. Trucking is just one link in the supply chain that has been greatly disrupted in the past couple of years, but it is a critical one required to move goods across the country. Fruit and vegetable growers that need to transport their produce know the …
As they battle HLB, growers must control costs wherever possible, including by applying pesticides and fertilizer more efficiently. With that in mind, Yiannis Ampatzidis is engaging artificial intelligence (AI) to develop a low-cost, smart tree-crop sprayer that can automatically detect citrus trees, calculate their height and leaf density, and count fruit. That way, growers target their spray more efficiently, so …
By Yiannis Ampatzidis and Ute Albrecht Optimizing nutrition is important for tree health and productivity and can improve tolerance to stresses and diseases. Good nutrient management requires regular field monitoring to identify problems and examine crop responses. Leaves need to be collected and sent to a specialized laboratory for detailed information on macronutrients and micronutrients, which is time-consuming and costly. …
