Ariel Singerman, economist with the University of Florida’s Institute of Food and Agricultural Sciences, reports on a grower survey he conducted regarding use of bactericides against HLB. “According to my survey, which included 62 growers accounting for approximately 160,000 acres, 92 percent of the growers applied bactericides,” Singerman says. “The majority did three applications, and they spent between $100 and …
Imagine camping in the deep woods. You’d want a tent with mesh that prevents bugs – even those as small as gnats – from entering into your wildlife hangout. That’s the idea behind citrus under protective screens, or CUPS, which helps keep away a pinhead-sized insect that causes citrus greening, University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS) scientists …
Some of Florida’s “best” citrus growers recently told Citrus Research and Development Foundation (CRDF) researcher Jim Syvertsen how they try to cope with HLB. There was much agreement among the growers on fertilization, irrigation, the management of psyllids that spread HLB, and bactericides that have been used against HLB for more than a year. Syvertsen says a survey conducted …
By Jaci Schrekengost As huanglongbing (HLB) continues to decimate citrus crops, researchers continue to search for new, efficient ways growers can manage the disease. HLB, also known as citrus greening disease, is vectored by the Asian citrus psyllid. The disease affects the entire tree, including the roots and fruit. Tripti Vashisth, assistant professor and citrus Extension specialist at the University …
By Arnold Schumann and Laura Waldo Florida citrus trees may require irrigation throughout the year due to the extremely sandy soils with low water-holding capacities and the warm subtropical climate with distinct drought periods in spring. Citrus trees are evergreen and may be actively growing at any time, with no true dormant phase. HLB-affected trees are particularly prone to multiple …
By Tacy Callies With the recent birth of the Georgia Citrus Association (GCA), many small commercial citrus groves are getting started in the state. Georgia’s newest citrus planting, however, is not a commercial grove. It’s a 100-tree installation that was planted this spring at the Mitchell County Correctional Institute. Dubbed MitCo Grow by a 4-H student, the project is the …
By Mongi Zekri, Bob Rouse and Jonathan Crane Hurricane preparation for citrus growers this year is the same drill as every year. Each year, growers look forward to the rainy season to help their young trees grow fast and their mature trees produce good crops. This year, growers will be praying for good distribution of rains following a year of …
Wauchula citrus grower and orange grove salesman Kenny Sanders was one of the growers sharing experiences at a recent grower roundtable meeting in Wauchula. Sanders tells why he attends the meetings and discusses several practices aimed at coping with HLB. “This is very interesting,” Sanders says of the roundtable meetings. “We hear from the growers ourselves, and today we learned …
Severe pruning combined with enhanced foliar nutrition did not prove cost-effective. By Monica Ozores-Hampton, Fritz Roka, Robert Rouse and Pamela Roberts Citrus trees affected by huanglongbing (HLB) become diminished, weak and develop dieback resulting in reduced production. Decline in fruit yield ultimately prevents economically acceptable commercial citrus production. Pruning and spraying foliar nutritionals are two practices being considered to restore …
A Dinuba, California-based company specializing in plant nutrition has developed a phone app that helps growers identify and treat crop nutrient deficiencies. The company — Nutrient Technologies, Inc. — has been manufacturing and selling agricultural fertilizer products since 1986 in the Central Valley and throughout California, specializing in citrus crops. The app, called Crop Nutrient Advisor, shows photos of plants …
By Tripti Vashisth Mineral nutrition plays an essential role in a plant’s life cycle and is critical for its growth and development. Since the early 19th century, the importance of mineral nutrition for plants has been recognized, and fertilization has become an important aspect of crop production. At least 17 mineral nutrients are considered essential for plants. These include carbon, …
By Jim Graham and Kelly Morgan Huanglongbing (HLB), greening and yellow shoot are names for the most devastating citrus disease in the world. Symptoms of HLB include a distinctive chlorotic mottle on fully expanded leaves. Infected shoots are stunted, and branches gradually die back as the symptoms appear in other sectors of the tree canopy. HLB reduces fruit size, weight …
The topic of nutrition takes center stage in the May issue of Citrus Industry magazine. Part two of an article co-authored by growers and a researcher presents case studies on how controlled-release fertilizer can boost the health of HLB trees. Also included in the May issue is an update on grower citrus nutrition trials being conducted by University of Florida. …
By Christopher Vincent I recently spent a morning with a grower who was trying to find out how efficient his citrus fertility program was. His fertilizer practices were carefully considered combinations of granular fertilizer and fertigation based on foliar sampling and yield history. We were there to observe some European consultants who were measuring mineral nutrient levels in the root …
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 …
Cost-share assistance is available from several sources for growers looking to implement improvements to best management practices. By Tacy Callies The names of the organizations and programs that provide funding to Florida citrus growers for best management practices (BMPs) projects — SWFWMD, FARMS, EQIP, etc. — can sound like a big bowl of alphabet soup. But in reality, they represent …
Greening disease, known as HLB, is a top concern for citrus growers worldwide. The April issue of Citrus Industry magazine is all about boosting the health of HLB-infected trees. Articles on this theme cover the use of controlled-release fertilizer, bicarbonate management, foliar nutrition and irrigation strategies. This month, for the first time Citrus Industry’s CEU Central article offers a continuing …
Virtually all Florida citrus growers have signed up to participate in the Florida Department of Agriculture and Consumer Services’ (FDACS) best management practices (BMPs) for water quality and water quantity. “They’ve done an extremely good job over the last 20 years that we’ve had BMPs,” says University of Florida researcher Kelly Morgan, the statewide BMP coordinator. “The (state) water act …
Several growers participating in a forum in Sebring on March 9 said trees are looking better this year than last year. They also agreed that postbloom fruit drop (PFD), a major problem last season, has not yet been a big issue this season. Grower Aaron Himrod of Himrod Citrus Nursery, a forum participant, says good tree condition and high fruit …
By Jim Hoffman This article is about my experiences with incorporating organic mulched materials into select areas of groves at Estes Citrus in the Indian River region. Our citrus groves consist of bedded, 40-acre blocks where it is common to have three or four distinct soil types in each block. Unfortunately, we have several sand-pond areas that have a history …
