Citrus growers have multiple options in their weed management toolbox to tackle such problems as parthenium, ragweed, sweet clover and amaranth. Ramdas Kanissery, weed scientist and assistant professor at the University of Florida Institute of Food and Agricultural Sciences Southwest Florida Research and Education Center, believes the right tool or combination of tools can improve yields and help protect trees. …
“We’re not going to have a silver bullet” for HLB, says Lorenzo Rossi, an assistant professor at the Indian River Research and Education Center. Instead, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) root biologist says that researchers are trying to keep citrus producing profitably. Rossi described some of his research efforts that focus on root health …
(UF/IFAS) — One of the University of Florida’s (UF) most promising professors has been nationally recognized as an industry leader for her scholarship and service. Lauren Diepenbrock, an assistant professor of entomology working at the UF Institute of Food and Agricultural Sciences (IFAS) Citrus Research and Education Center recently received the 2019 Southern Region Integrated Pest Management (IPM) Center Friends …
The March episode of the All In For Citrus podcast covers how the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) is operating under COVID-19 restrictions and some of the research that continues. CREC Center Director Michael Rogers starts the episode with the impacts COVID-19 is having on the citrus research team …
The December All In For Citrus podcast has critical insights on citrus production, including contract issues, a view from Brazil, soil health research and the Winter Weather Watch program. Numerous Florida citrus growers have no contracts and no offers, or very low offers, for their juice oranges this season. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus …
A citrus soil health field day recently attracted about 40 people to the Howey-in-the-Hills area to see growers’ success using cover crops and compost on Florida groves once stunted by HLB. Event organizer Juanita Popenoe, commercial fruit production Extension agent for Lake, Marion and Orange counties, comments on the groves’ success. Popenoe is with the University of Florida Institute of …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will host a field day focused on improving citrus soil health, a topic of growing interest to researchers and growers. With the challenges of citrus greening, there is an increased need for understanding overall tree health, including the soil, Juanita Popenoe, UF/IFAS Extension multi-county agent, said. The field day …
The fate of pesticides By Juanita Popenoe Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. I have had several problems brought to me recently that were caused by pesticide residues in …
As Florida citrus growers learn to live with HLB, greater attention is being paid to plant nutrition. Nutrition takes center stage in the April issue of Citrus Industry magazine. Both growers and researchers are exploring the use of cover crops in grove row middles to enhance tree nutrition. The April issue includes a case study on eight years of cover …
By Larry Duncan Successive hard freezes in Florida in the late 1980s resulted in widespread replanting of citrus groves. Within a few years, many groves on the Central Ridge had discrete patches of poorly growing, chlorotic young trees amid patches of vigorously growing trees. Stubby root symptoms on the declining trees suggested damage by sting nematodes (Belonolaimus longicaudatus). This nematode …
University of Florida Institute of Food and Agricultural Sciences soil microbiologist Sarah Strauss discusses her research on ways to potentially use microbes to improve tree root health. She says microbial communities in the soil can be manipulated indirectly by changing the soil environment or directly by adding specific organisms to the soil. “We’ve seen impacts on the overall soil microbial …
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 …
When growers in Central Florida need help with an alternative crop to citrus, they turn to Juanita Popenoe. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension agent spends her days helping farmers who are looking for options to diversify their groves impacted by citrus greening disease. “Since citrus greening has hit the industry so hard, citrus …
As a girl in her garage in Palm Bay, Florida, Lauren Diepenbrock, already a budding scientist, peered through the lens of her microscope and marveled at the magnification. “As a kid, I played in the woods and brought back all sorts of ‘finds,’ including a snake skeleton, none of which my mom allowed in the house,” said Diepenbrock, an assistant …
Oranges imported to Florida — primarily from Brazil and Mexico — are projected to surpass what is grown in the hurricane-damaged Sunshine State this season. The Florida Citrus Commission on Wednesday approved an adjusted $17.8 million budget that takes into account an increase in imports that will help cover crops lost in September to Hurricane Irma. “With Hurricane Irma’s impact …
By Kelly Morgan Nitrogen and phosphorus are essential nutrients for plants and animals and are the limiting nutrients in aquatic environments. The correct balance of both nutrients is necessary for a healthy ecosystem; however, excessive nitrogen and/or phosphorus can cause significant water-quality problems. Typically, nitrogen is the limiting nutrient in spring and surface water systems. Therefore, even modest increases in …
The U.S. Department of Agriculture (USDA) is extending the deadline for farmers to apply for Stages 1 and 2 of the Supplemental Disaster Relief Program (SDRP) to Sept. 30. Additionally, USDA’s Farm Service Agency (FSA) is providing greater flexibility for farmers who experienced quality losses on eligible crops. When applying for this program, farmers who experienced quality-related discounts can use verifiable and reliable documentation to …
Researchers have discovered a soil bacterium that helps citrus plants grow by releasing a natural chemical signal that improves the plant’s ability to take up nutrients. The finding could lead to new biological products designed to improve citrus tree health and fertilizer efficiency. An article about the study was published in Horticulture Research. The authors are Hongfei Li, Dongxin Liu, …
A new study demonstrates that proline biostimulation can significantly enhance freezing stress tolerance in citrus by stabilizing photosynthesis, strengthening antioxidant defenses and improving carbohydrate metabolism. The findings offer promising strategies for protecting citrus crops from damaging low-temperature events. Proline biostimulation is the application of the amino acid proline to plants to help them resist harsh environmental conditions like freezing cold, …
The Citrus Industry section of the August issue of Specialty Crop Grower magazine features practical production advice, a new variety resource, citrus marketing insights and more. The section opens with a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) article explaining crop load management and alternate bearing in citrus. Fernando Alferez and Muhammad A. Shahid discuss why citrus …
