By Ajia Paolillo 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. Integrated pest management (IPM) uses a combination of methods to keep pest populations at an acceptable level, which are economical …
Visual identification of nutrient deficiencies and leaf damage is an important diagnostic tool for fine-tuning management of citrus. Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, shared how UF/IFAS researchers have used artificial intelligence (AI) to diagnose citrus nutritional deficiencies, diseases and pest damage. According to Schumann, disease and pest symptoms on leaves may cause …
By L.M. Diepenbrock Insect and mite management is a year-round challenge in Florida citrus. With the warm climate, pests are at the ready as soon as plant resources are available to them. With knowledge of insect and mite biology in relation to tree phenology, plans can be developed to protect fruit and maintain productive citrus trees. Populations of many of …
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.

Growers and agricultural workers should learn to identify the symptoms of CBS even if they are not located …
Citrus growers told Environmental Protection Agency (EPA) officials why they want the insecticide aldicarb registered for use in Florida citrus, and discussed their problems with citrus greening. EPA cancelled the use of Temik, the Bayer brand name for aldicarb, on citrus at the end of 2011. Mike Aerts of the Florida Fruit & Vegetable Association (FFVA) said the Oct. 22 …
The use of chemicals for HLB-spreading Asian citrus psyllids (ACP) and other pests has raised several concerns, Jawwad Qureshi reported in a virtual Florida Citrus Growers Institute presentation. Those concerns include pest resistance, costs and diminishing biological control of pests, as well as concerns about health and the environment. Qureshi, a University of Florida Institute of Food and Agricultural Sciences …
By Brenda Eubanks Burnette The headline of a Wilson & Toomer Fertilizer Company advertisement in a 1949 Citrus Industry magazine read “how to think UPSIDE DOWN — and make more money!” It included the following copy: “If a tree can be said to think at all — it thinks from the bottom up — just opposite to Man. To make …
Citrus growers can learn more about managing Asian citrus psyllids and other pests in a workshop Jan. 8 at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC). The psyllid can transmit the bacteria associated with greening disease to citrus trees and has already caused severe damage to Florida’s multi-billion-dollar-a-year citrus industry. …
Beginning this week, Florida citrus growers will have an updated resource to help them keep groves productive despite the ever-present threat of huanglongbing, the bacterial malady also known as HLB or citrus greening disease. Experts with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have just completed a 180-page technical handbook, “Florida Citrus Production Guide 2018-2019.” It …
By Arnold Schumann, Laura Waldo, William Holmes, Gary Test and Tim Ebert Artificial intelligence (AI) is increasingly common in electronic devices at home or work, in social media, video streaming services, electronic commerce, and in internet search engines.

By Jawwad A. Qureshi, Philip A. Stansly and Lukasz L. Stelinski Pest management has always been important for citrus production in Florida. It has become even more critical following invasion of the Asian citrus psyllid (ACP) and citrus leafminer (CLM), due to their association with huanglongbing (HLB or citrus greening) and canker diseases, respectively. ACP and CLM develop and reproduce …
It may not be long before a grower sips coffee and works on the computer while a robot roams the grove checking for HLB-spreading psyllids and other pests and diseases. That’s thanks to machine vision software. University of Florida Institute of Food and Agricultural Sciences scientist Arnold Schumann tells about research he has been conducting. Schumann says researchers have developed …
