Alternatives to Glyphosate in Groves
There are good reasons glyphosate is the most popular herbicide in U.S. citrus groves, but there are also concerns about its use, says Ramdas Kanissery. Because of the concerns, the University of Florida Institute of Food and Agricultural Sciences weed scientist suggests alternatives that growers can consider. Kanissery discusses glyphosate and its alternatives in a presentation originally intended for the …
Soil Organic Matter Helps Fight HLB
By Sean Stokes, Thomas Borch and Pankaj Trivedi The benefits of soil organic matter (SOM) in agriculture have been well documented and include both improved water and nutrient retention. SOM is also essential for a properly functioning rhizosphere microbiome. However, the natural level of SOM in the sandy, acidic soil of Florida’s citrus grove regions is often around 1 percent, …
Weed Management: Use Multiple Methods
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. …
Soil Health Focus for HLB
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 …
Citrus Soil Health an Important Part of Overall Tree Health
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 …
Citrus Industry Magazine CEU 2019 Article #4
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.

Sneak Peek: April 2019 Citrus Industry Magazine
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 …
Sting Nematodes: A Growing Problem for Young Trees
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 …
Soil Microbial Communities for Citrus
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 …
Components of a Healthy Citrus Soil
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 …
New UF/IFAS Entomologist: From a Kid’s ‘Lab’ to Helping Citrus Growers
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 …
Citrus Imports Playing Bigger Role in Florida
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 …
