Associate Professor Fernando Alferez and his team at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) learned several years ago that individual protective covers (IPCs) protect newly planted trees from HLB. They do that by excluding the Asian citrus psyllids (ACP) that spread the devastating citrus disease. But multi-county citrus Extension agent Mongi Zekri noted that IPCs …
Individual protective covers (IPCs), used primarily to protect young citrus trees from HLB-spreading Asian citrus psyllids, have become ubiquitous in Florida citrus groves in recent years. New University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows the trees grown under the IPCs also grow well for a few years after growers remove the bags. Growers typically remove …
As recently as five years ago, Florida citrus growers did not routinely put individual protective covers (IPCs) on their trees as part of their grove management. Now, the mesh IPCs cover at least 1 million trees on about 17,000 acres, mostly thanks to experimentation by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez. IPCs keep …
By Amir Rezazadeh Citrus trees face many threats that can impact fruit development and overall tree health. Pests, including aphids, mites and other insects, can damage fruit and transmit diseases. Extreme weather events, such as hailstorms or heavy rains, can cause physical harm, leading to blemishes and reduced market value. In addition, citrus growers have faced persistent challenges because of …
By Fernando Alferez Five years of University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) data in trials across the state have shown that individual protective covers (IPCs) are effective in preventing HLB until they are removed. This has been shown in sweet orange varieties such as Valencia and Hamlin. In these varieties, it has been demonstrated that the …
The use of individual protective covers (IPCs) to safeguard young citrus trees from HLB has become a common practice in Florida groves in recent years. Fernando Alferez, an assistant professor of citrus horticulture with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has led the research effort to study IPCs and their effectiveness in preventing HLB. He …
Foliar sprays of insecticides timed to citrus flushing provided a significant reduction in Asian citrus psyllid (ACP) populations compared to standard grower practices, researcher Jawwad Qureshi reported. Timing sprays to flushing also led to a reduction in sprays, the University of Florida Institute of Food and Agricultural Sciences associate professor of entomology said in a virtual presentation on Feb. 22. …
Researchers and growers have found that individual protective covers (IPCs) can keep young trees free of HLB for two or more years while providing additional benefits like improved tree growth. The IPCs work by keeping HLB-infecting Asian citrus psyllids out of the tree canopies. But trees outgrow the covers and must eventually be removed. Researchers have found that about 60% …
By Larry Duncan and Fernando Alferez Newly planted citrus trees are far less tolerant of pests and diseases than when mature. Sting nematode (Belonolaimus longicaudatus) was not considered a serious economic threat to Florida citrus until successive hard freezes in the 1980s caused widespread replanting of groves. Patches of stunted, declining trees caused by the irregular distribution of sting nematodes …
Individual protective covers (IPCs) do an excellent job keeping HLB-spreading Asian citrus psyllids (ACP) out of young citrus trees, showing a 99.6% reduction in ACP compared to control trees. But they don’t provide “one and done” pest control, according to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock. In fact, IPCs “create a perfect environment …
How well reflective mulch, kaolin clay and individual protective covers (IPCs) hold up to HLB, canker and greasy spot diseases was researcher Megan Dewdney’s topic at the 2022 Citrus & Specialty Crop Expo. Dewdney is a University of Florida Institute of Food and Agricultural Sciences associate professor of plant pathology at the Citrus Research and Education Center. The research project …
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 …
By Larry Duncan Citrus trees in Florida soils infested with diaprepes root weevil (Diaprepes abbreviatus) or sting nematode (Belonolaimus longicaudatus) frequently contend with devastating damage to their root systems. This is made even worse by root loss due to huanglongbing (HLB) disease. Where soil conditions are conducive to the insect or nematode, it is very difficult to prevent major economic …
By Lauren Diepenbrock, Megan Dewdney, Fernando Alferez, Jawwad Qureshi and Ozgur Batuman Individual protective covers (IPCs) are becoming commonplace in citrus production to support the development of young trees after planting. IPCs are made of fine mesh and are intended to keep Asian citrus psyllids (ACP) off young plants. Because ACP can transmit the pathogen that causes citrus greening/huanglongbing, preventing …
By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …
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 …
By Fernando Alferez, Ozgur Batuman, Susmita Gaire, Ute Albrecht and Jawwad Qureshi In previous and ongoing research performed at the Southwest Florida Research and Education Center (SWFREC), we have demonstrated that individual protective covers (IPCs) are effective in keeping psyllids off newly planted citrus trees. Trees have been HLB-free for more than two years after planting, and the IPCs provide …
