By Ramdas Kanissery Adjuvants (derived from Latin, adiuvare: to aid or help) are materials added into an herbicide spray solution that improve handling, performance and crop safety. To be effective, an herbicide must overcome certain environmental and biological obstacles before entering and acting in the weeds. For example, environmental conditions like hot and dry weather will result in a thicker …
Nematologist Larry Duncan discussed efforts to control the root pests sting nematode and Diaprepes root weevil in his presentation during the virtual April 6 Florida Citrus Growers’ Institute. Duncan works at the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Citrus Research and Education Center. The sting nematode and Diaprepes are especially concerning in the age of HLB, …
IMG Citrus, a citrus grower, packer and shipper in Vero Beach, Florida, recently bought a 2,500-acre grove in Charlotte County. The grove increases the company’s control of citrus land management in Florida by 27%; it now has 11,387 acres. The property was acquired from the Packers of Indian River. The grove was originally planted in the 1990s and known as …
A presentation at the recent Citrus Pest & Disease Prevention Committee State of the Central Valley meeting in California highlighted the importance of scouting for Asian citrus psyllids (ACP) in groves. Scouting becomes even more critical as the risk of ACP and HLB, the disease the insect transmits to trees, rises. The presenter, University of California (UC) Riverside Extension Specialist …
By Megan Dewdney Citrus black spot is one of the newer diseases to worry Florida citrus growers. The fungal disease was first detected in Southwest Florida in 2010. The vast majority of finds have been in the southwestern citrus-producing counties of Collier, Hardee, Lee, Charlotte and Glades, but the disease has slowly moved northward. Black spot is still considered a …
Protect Young Citrus from Grasses, Broadleaf Weeds & Nutsedge Weeds in citrus groves can cause yield loss of up to 33%, according to research published by the University of Florida (UF) Citrus Research & Education Center. This significant – yet largely preventable – level of yield loss can be due to weeds that interfere with harvesting, serve as alternate hosts …
By targeting Asian citrus psyllids on an area-wide scale and focusing on several individual properties simultaneously, growers can minimize psyllid movement between groves, reduce HLB transmission and maintain citrus production at a profitable level. Generally, most psyllid sprays are applied on a calendar or threshold basis, resulting in high-spray frequencies and associated costs. Because of the Asian citrus psyllid’s high …
By Emilie Demard and Jawwad Qureshi Managing the Asian citrus psyllid (ACP), a vector of huanglongbing (HLB), is critical for reducing disease incidence and improving tree health. Growing citrus under screened structures, referred to as citrus under protective screen (CUPS), protects trees from ACP and HLB. CUPS provides an opportunity to produce premium-quality fresh fruit by preventing psyllids and HLB …
Florida citrus production has decreased for almost two decades. According to Marisa Zansler, director of economic and market research at the Florida Department of Citrus, the two main factors for the state’s steady decline are citrus greening (huanglongbing, known as HLB) and Hurricane Irma. Zansler presented staggering statistics during the Florida Agricultural Policy Outlook Conference on Feb. 26 that showed …
By Jawwad Qureshi Managing the Asian citrus psyllid (ACP) is critical because of its role in spreading huanglongbing (HLB). Biological control is one method for ACP control. It is essential for developing integrated and sustainable pest management strategies. Biological control has always been a vital component of citrus pest management in Florida; understanding its contribution to the mortality of ACP …
As growers strive for sustainability in the HLB era, biological controls are playing an increasingly important role in citrus production. The March issue of Citrus Industry magazine features some of the latest biological control research. An article by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Jawwad Qureshi looks at three types of biological control agents used …
It may not be the answer Florida citrus growers want to hear, but it is likely to be several years before a citrus greening remedy is put in place to combat the destructive disease. University of Florida professor Fred Gmitter shared his assessment on possible citrus greening solutions during a recent American Seed Trade Association webinar. “We learn a lot …
Citrus growers and industry members recently gathered virtually to discuss the Asian citrus psyllid (ACP) and huanglongbing disease (HLB) situation throughout the Central Valley of California. The reason for the concern is a negative trend seen in 2020. ACP DETECTION HISTORYACPs, the vectors for the disease, are widespread in Southern California where HLB-infected trees have been found. There are ongoing …
Steve Johnson, owner and general manager of Johnson Harvesting, was elected chairman of the Florida Citrus Commission (FCC) this week. He succeeds Ned Hancock in the chairman position. The FCC oversees the Florida Department of Citrus. Johnson is a fourth-generation citrus grower and cattle rancher based in Wauchula. In addition to managing the operations of the citrus harvesting and brokerage …
By Brenda Eubanks Burnette In January, the Florida Department of Agriculture and Consumer Services (FDACS) hosted virtual “Florida Citrus Squeeze” events at elementary schools throughout Florida with Chef Paula Kendrick and Miss Florida Citrus Leila Sabet. The program was announced in December to Florida food service personnel and teachers that participate in the division’s Harvest of the Month Program. Participating …
By Lauren M. Diepenbrock While there are many species of ants in Florida, the invasive fire ant (Solenopsis invicta) is the one most people are familiar with. These ants can be pests in agriculture, landscapes and structures. The pest’s ability to use a variety of habitats and resources makes it challenging to manage. In citrus groves, fire ants can be …
By Xavier Martini and Danielle Sprague Cold-hardy citrus, that is, citrus grown above the 30th parallel north, is a blooming industry. In less than 10 years, the acreage in North Florida has gone from almost nonexistent to approximately 1,000 acres. Growers in the region plan to plant more in the coming years. In Georgia, there are approximately 2,000 acres across …
Phytophthora and leprosis diseases can each substantially reduce productivity of a citrus tree, but when they attack trees already weakened by HLB, the result can be fatal. Ozgur Batuman, assistant professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), explained how co-infection impacts HLB-infected trees during a recent UF/IFAS webinar. PHYTOPHTHORA DISEASESPhytophthora species are soil-borne fungal pathogens …
One of the main issues for citrus crop growers is the quick spread of fungal and bacterial diseases due to warm, wet growing conditions. Without proper methods to prevent and control diseases, crop yield can be greatly reduced, and groves can become ruined. How do you produce a healthy citrus crop while keeping diseases under control? For generations, growers have …
Weed management is a key component of Florida’s citrus production. A warm, humid climate and frequent rainfall provide a favorable environment for weed emergence and growth in citrus groves. Steve Futch, a former multi-county citrus Extension agent for the University of Florida Institute of Food and Agricultural Sciences, delivered a presentation during the 2021 virtual Southeast Regional Fruit and Vegetable …
