Research studies show that about 60% of Florida citrus trees are infected by HLB disease within six months of planting. By one year, 100% of citrus trees are infected. For that reason, the use of individual protective covers (IPCs) has become very popular to protect young citrus trees from the Asian citrus psyllid (ACP). The covers have proven to be …
Brazil’s Fundecitrus has launched the Insecticide Rotation Guide for Psyllid Control. Its aim is to help producers control the insect vector of citrus greening, highlighting the importance of proper rotation of products to avoid the selection of resistant psyllids. The resistance of insects and mites to pesticides can compromise the effectiveness of products and, consequently, the control of the pest …
While many citrus growers use similar strategies to cope with HLB, no two approaches are exactly the same. One grower who uses a very different method to manage citrus greening is Chip Henry. In the May cover story of Citrus Industry magazine, he tells how growing organically has helped him successfully fight the disease. Sometimes, production practices aimed at protecting …

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has revised the conditions for interstate movement of citrus fruit from areas quarantined for both sweet orange scab (Elsinöe australis, SOS) and citrus canker (Xanthomonas axonopodis, CC). The revisions allow for the movement of fruit to packinghouses located in contiguous states that are not quarantined for either disease. …
By Lukasz L. Stelinskiand Jawwad A. Qureshi Asian citrus psyllids (ACP) are at the mercy of their host (citrus) for survival. They need flush to lay eggs and for the nymphs to develop. Prior to HLB, the majority of flushing had been fairly predictable and occurred in the early spring and late summer. The occurrence of flush in young trees …
An update on citrus diseases in Brazil was part of a recent U.S. Department of Agriculture Foreign Agricultural Service (FAS) report. GREENING INCREASINGAccording to the 2021 citrus greening survey conducted by Fundecitrus, 43.4 million trees, or 22.37%, of the trees in the commercial area of the state of São Paulo and the western part of Minas Gerais are affected by …
With the new year, Citrus Industry debuts a new look in the January issue! The magazine has been refreshed with a redesign, but readers will still find the same great content they rely upon to produce the best citrus. The January issue features a focus on pest management, with four articles covering this topic. Two of these articles address biological …
About four years ago, Fernando Alferez started to test whether citrus trees grown inside protective mesh covers could be kept safe from the HLB-spreading Asian citrus psyllid. New research from Alferez shows that citrus trees grown under individual protective covers (IPCs) show no signs of HLB, also known as citrus greening. Specifically, scientists found that psyllids cannot penetrate the IPCs …
In recognition of biosecurity threats such as HLB, a new five-year biosecurity program, CitrusWatch, has been launched in Australia. This program is funded by Hort Innovation through the citrus R&D levy and by Plant Health Australia (PHA) using the citrus plant health levy. The program is led by PHA, with Citrus Australia coordinating program activities. The Northern Territory Department of Industry Tourism …

The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is providing growers with regular flower bud advisories as the critical time for citrus grove management begins this winter. UF/IFAS associate professor Tripti Vashisth restarted the advisories Dec. 2 and will continue providing them every other week through the spring. The advisories provide critical information about the intensity and …
At the 2021 Citrus Expo, entomologist Lukasz Stelinski suggested ways growers can manage HLB-spreading Asian citrus psyllids (ACP) while reducing costs. Some of the University of Florida Institute of Food and Agricultural Sciences entomologist’s key points follow: Psyllid density is related to tree stress; more psyllids lead to higher damage, compromising tree health and yield. Spray for adults at bud …
The low initial U.S. citrus crop forecast for the 2021–22 season points to the need to plant more trees to sustain the country’s citrus industry. The November issue of Citrus Industry magazine features articles that will help growers take care of their young trees. Two articles help answer the question of what to plant.

One of the unique ways of managing citrus greening disease developed by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers is not for all producers. Citrus under protective screen (CUPS) is just too expensive for all growers to take advantage of, says Fred Gmitter, a UF/IFAS citrus breeder. “It’s an extremely expensive investment,” Gmitter says. “For that …
