A three-year Louisiana State University Agricultural Center (LSU AgCenter) study is investigating the pros and cons of growing citrus inside or in containers. “So far, we are finding that the pros are outnumbering cons,” said Anna Timmerman, LSU AgCenter horticulture agent in St. Bernard and Plaquemines parishes. Early results of Timmerman’s research show that growing citrus indoors produces a high-quality …
By Mongi Zekri For maximum efficiency of a grove, it is essential that every location is occupied by a tree and that every tree is healthy. Prompt replacement of dead and declining trees means higher average long-term returns from the grove. If the declining trees remain in the grove, they keep getting weaker and yield less fruit each year. Therefore, …
By Kelly T. Morgan, Davie Kadyampakeni and Tripti Vashisth This article reviews current University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus fertilizer recommendations and provides updated information about recently approved recommendations for secondary macronutrients and micronutrients. Citrus growers have been very concerned about fertilizer applications and nutrient management since citrus greening (huanglongbing or HLB) was found in …
Norwegian company Desert Control has developed a liquid natural clay (LNC) that reportedly restores and enhances soil ecosystems to reduce usage and improve efficiency of water, fertilizers and natural resources for agriculture and other uses. It has signed contracts with the Limoneira Company to apply LNC to citrus trees in California and Arizona. The project’s initial scope is to apply …
By Tripti Vashisth In Florida, it is the time of year to start following citrus flower bud induction conditions for next year’s bloom. Citrus flower bud induction starts in the fall and usually is complete by early January. Low temperatures first stop growth and then promote induction of flower buds as more hours of low temperatures accumulate (below 68 degrees). …
Citrus growers producing for the fresh market should always ensure their fruit’s peel remains unblemished and without defect. This will protect the fruit against infection and consumers choosing not to purchase the fruit. Mark Ritenour, professor of postharvest technology at the University of Florida Institute of Food and Agricultural Sciences, spoke during the recent Cold-Hardy Citrus Field Day at the …
By Mongi Zekri Pruning is an important grove practice that increases sunlight penetration within the tree canopy. Sunlight enhances flowering, fruit quality and color development. Sunlight also allows foliage to dry quickly after a rain shower, which reduces problems of fungal diseases. Pruning trees can improve fruit quality and increase fruit size. However, tree response to pruning depends on scion …
The requirement that the Florida Department of Agriculture and Consumer Services (FDACS) conduct Best Management Practice (BMP) implementation verification visits has been temporarily suspended for several counties impacted by Hurricane Ian. The action was taken Oct. 31 by Florida Commissioner of Agriculture Nikki Fried. The 60-day suspension is effective for the counties of Brevard, Broward, Charlotte, Collier, DeSoto, Flagler, Glades, …
The Fruit Crop Physiology Lab at the North Florida Research and Education Center (NFREC) in Quincy is focused on developing a sustainable and profitable cold-hardy citrus industry in the southern United States. To do that, it is conducting research-driven Extension projects. The NFREC is part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The lab collaborates …
By Chris Oswalt Growers may have compelling reasons to collect and analyze citrus leaf samples at different times of the year. Current tables allow growers to interpret the results of their citrus leaf analysis based on the collection and analysis of 4- to 6-month-old leaves from non-fruiting twigs (Figure 1). This begs the question of the potential consequences of interpreting …
Give trees a bit of relief with frequent irrigation and kaolin particle film. By Christopher Vincent Hurricane Ian caused damage to orange trees, knocking fruit on the ground, twisting and breaking limbs, stripping leaves off trees and flooding soil. Although lots of damage was visible immediately, the after-effects will continue to rear their ugly heads in the months to come, …
The California Citrus Mutual (CCM) Marketing Committee —comprised of growers, shippers and marketers — anticipates the state’s 2022–23 navel orange and mandarin crops will be larger than last season. The U.S. Department of Agriculture also predicted larger California crops in its initial citrus forecast for the 2022–23 season. The navel orange crop will be approximately 10% over the previous season’s …
Dundee Citrus Growers Association (CGA) and its members will more than double the area growing fresh citrus under protective screen (CUPS) with the addition of a second CUPS project. The new project will be located in southern Polk County, just east of Fort Meade. “Once fully developed, the 622-acre parcel will contain approximately 500 acres of CUPS … bringing our …
Citrus growers have been watching developments with water regulation closely in recent years. The 2022 Florida legislative session addressed some issues that had developed with the state’s best management practices (BMPs) program. Ernie Barnett, president of the Florida Land Council, gave Citrus & Specialty Crop Expo attendees a recap of the BMPs changes and provided a big-picture perspective of the …
Agriculture students at four Florida colleges and universities can apply for Florida Fertilizer & Agrichemical Association (FFAA) Ag Scholarships by Sept. 9. The schools are Florida A&M University (FAMU), Florida Southern College (FSC), University of Florida (UF) and Warner University. The FFAA Scholarship Fund offers scholarships to qualified upper-level university and college students in agriculture or a very closely-related major. The scholarships are …
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 …
In the quest for better fruit retention in HLB-infected citrus, there has been a good deal of attention placed on the use of plant growth regulators to fight fruit drop. Gibberellic acid (GA) has been the focus of new research in recent years to establish refined timing of applications to optimize results in Florida citrus. Much of that research has …
By Amir Rezazadeh Saline soil and water damage many citrus groves in Florida. In general, when the dissolved salt concentration in soil or water increases, it is referred to as “saline” soil or water. But how much increase in salt concentration makes soil or water saline? Citrus plants’ major reactions to excessive salt in the soil or water are reduced …
Whether a citrus grove is thriving or not is often based on what is observed above the ground. However, the best measurement of fertility comes from what’s happening below ground—in the soil microbiology. There is a complex community of living organisms, everything from worms and insects to tree roots. One of the most important elements is soil microbes. Soil microbes …
By Ute Albrecht There have been numerous reports of malformed roots in field-grown citrus trees recently. The rootstock propagation method is often suspected as the culprit. Before drawing quick conclusions, it is important to recognize that there are many different factors that can influence the root structure of a citrus tree aside from the propagation method. These include the genetic …
