By Meryam Manzoor, Jamie D. Burrow, Taylor Livingston and Tripti Vashisth Effective nutrient management and accurate nutritional analysis are critical for tree growth and maximum yield. Historically, nutrient management for healthy citrus trees involved annual leaf sampling from July to August, with subsequent fertilization plans based on a single nutrient analysis. Almost all commercial citrus groves in Florida are affected …

Imagine a future where nurseries can effortlessly manage their plants with cutting-edge automation technologies, using potting or weed-spraying robots instead of having to dig each hole or spray each pot by hand. With the help of a $9.8 million grant from the U.S. Department of Agriculture National Institute of Food and Agriculture, this vision is becoming a reality. The University …
By Peter Chaires Many have been following the development of the Georgia citrus industry with great interest and curiosity. Though satsuma remains the dominant fresh citrus crop, other varieties are in varying stages of trial and adoption. The University of Georgia (UGA) has been supporting citrus growers in this process for more than a decade. Wayne Hanna, though his appointment …

The fate processes for pesticides fall into three major types: adsorption, transfer and degradation. PESTICIDE ADSORPTION The adsorption process binds …
By Ariel Singerman Orange yield in Florida has decreased by more than 80% since HLB was first found in the state in 2005. It is hard to find another example in recent history of an industry as iconic as Florida citrus that has declined so significantly as a consequence of a plant disease. As a comparison, at the global level, …
When HLB arrived in Florida, it changed the world for citrus growers, and a lot of other things had to change with it. One of the biggest changes has been how growers manage their fertilizer programs. The nutrient recommendations that had been developed by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) before HLB became outdated because …
University of Florida Institute of Food and Agricultural Sciences Extension agent Mongi Zekri recently discussed numerous ways growers can enhance their nutrient programs for better tree and fruit performance. TIPS FOR MAKING ADJUSTMENTS Zekri offered the following tips for adjusting a fertilizer program. SOIL TESTING Soil testing is most effective when done annually, Zekri suggested. “Choose a lab you trust …
The virtues of daily irrigation and increased micronutrient applications were among key points researcher Davie Kadyampakeni made in an Aug. 13 discussion of citrus production in the HLB era. Kadyampakeni is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of soil, water and ecosystem sciences at the Citrus Research and Education Center in Lake Alfred. …
The U.S. Department of Agriculture National Institute of Food and Agriculture (USDA/NIFA) has invested more than $250 million to find a solution for HLB. One example of USDA NIFA-funded research is citrus under protective screen (CUPS). University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist Arnold Schumann and colleagues began testing CUPS at the Citrus Research and Education Center …
By Brenda Eubanks Burnette In the early 1900s, Florida Governor Napoleon Broward (1905–09) persuaded the Legislature to drain the Everglades and finance a canal system by selling off large blocks of land for $2 per acre. Once drained, the area housed rich fertile soil and, in 1906, millionaire R.P. Davie bought almost 28,000 acres. By 1909, settlers arrived in response …
By Mongi Zekri Foliar fertilizer application is certainly not a new concept to the citrus industry. For over six decades, foliar fertilization has been recommended to correct zinc, manganese, boron, copper and magnesium deficiencies in citrus. It is now common knowledge in agriculture that properly nourished crops may tolerate insect pests and diseases. Traditionally, citrus growers try to achieve optimum …
By Davie Kadyampakeni and Miurel Brewer Row middle management is a key area that can improve tree performance. Row middles encompass 80% of citrus orchards, and 70% of the root system of citrus trees was located in row middles before huanglongbing (HLB). Typically, Florida citrus growers manage row middles using physical, chemical and mowing practices, often leaving them free of …
