In the ongoing battle against Huanglongbing (HLB), also known as citrus greening, Individual Protective Covers (IPCs) may be a powerful tool for Florida citrus growers. These mesh covers, designed to exclude (keep outside) the Asian citrus psyllid (ACP), vector of HLB, offer a non-chemical and cost-effective strategy to protect citrus trees at early stages, from planting during their most vulnerable years. According to UF/IFAS research, as outlined in EDIS publication<a href="https://edis.ifas.ufl.edu/publication/HS1425" target="_blank" rel="noopener"> HS1425, </a>IPCs work highly efficiently, excluding psyllids and preventing HLB infection. While the plants covered may remain HLB-free for up to three years, once uncovered, symptoms and positive results for the disease can take as little as six months.
&nbsp;
<h3>Material and Installation</h3>
Commercially, currently, IPCs are made either from high-density polyethylene (HDPE) or polyvinyl, with a mesh size of 50 (0.297 mm holes), which is small enough to block psyllids. So, a proper installation and maintenance area is fundamental: first, covers may be (or not?) secured right after planting, below the graft union, to PVC poles to prevent their collapse.
&nbsp;
<h3>When IPCs Become a Risk? </h3>
Along with the benefits, IPCs can also incur a liability if not properly maintained. Most common issues are:

</ul>
&nbsp;
<h3>Light: A Double-Edged Sword</h3>
IPCs and Citrus Under Protective Screens (CUPS) may both modify the light and environment for the inside plants due to the cover material. While changes in light (wavelength and refraction) inside the covers can enhance photosynthesis and growth, excessive shading or deformation of branches can reduce light interception and hinder their development.
&nbsp;
<h3>Some Recommendations</h3>
While the plants start growing, make sure:
1. Inspect IPCs inside—Especially least seasonally and after storms.
2. Replace IPCs when damaged or too small to allow trees to grow.
3. Scout for pests and diseases, even inside.
4. Make sure proper light and air circulation, and avoid moisture buildup.
5. Remove IPCs in a timely manner to prevent growth deformations.
&nbsp;
Remember, before considering fancy strategies, technologies, or fertilizers, citrus trees require their basic nutritional pillars—water (H₂O), carbon dioxide (CO₂), and light. These are the true drivers of photosynthesis and growth. Without them, no nutrient program will succeed.

Florida’s citrus groves have faced enormous challenges over the last two decades. The Asian citrus psyllid has spread citrus greening disease, known as Huanglongbing, or HLB, to trees across the state. The result is a decline in citrus production of more than 72 percent.

Florida’s citrus groves have faced enormous challenges over the last two decades. The Asian citrus psyllid has spread citrus greening disease, known as Huanglongbing, or HLB, to trees across the state. The result is a decline in citrus production of more than 72 percent. To fight the pest, growers often rely on imidacloprid, or IDP, a systemic insecticide that trees take up through their roots. But <a href="https://blogs.ifas.ufl.edu/swsdept/2024/02/15/members-of-uf-ifas-department-of-soil-water-and-ecosystem-sciences-contribute-to-book-on-sandy-soils/" target="_blank" rel="noopener">Florida’s sandy soils</a> are highly porous and low in organic matter. These conditions increase the risk that pesticides can move rapidly through the soil and contaminate shallow groundwater.
A new study from the University of Florida Institute of Food and Agricultural Sciences and collaborators in Spain examines this issue closely. Scientists looked at how water and IDP move through sandy soils under both saturated, or heavy rainfall and flooding, and unsaturated, or typical field, conditions. The research comes from Qudus Uthman’s 2023 doctoral <a href="https://ufl.zoom.us/rec/share/b68Gaa8e4H9aj84SWz4P0jF18IHaLS-IvHG5y-8TTzwhKN6QyoVsApFym_8CKm9o.mR4fIcWmNiPS-PFj?startTime=1688583310000" target="_blank" rel="noopener">dissertation</a>.

<h5>Why Sandy Soils Matter</h5>
Florida’s <a href="https://edis.ifas.ufl.edu/publication/SS655#:~:text=et%20al.%202010).-,Entisols,-Entisols%20are%20soils" target="_blank" rel="noopener">Entisols</a> and <a href="https://edis.ifas.ufl.edu/publication/SS655#:~:text=tropical%20nursery%20crops.-,Ultisols,-Ultisols%20are%20soils" target="_blank" rel="noopener">Ultisols</a> contain more than 90 percent sand and less than 0.5 percent organic matter. These conditions make it challenging for farmers to apply and control fertilizers and pesticides. Large rain events or too much irrigation can quickly saturate the citrus critical root zone (CCRZ). This zone extends 60 centimeters from the surface into the soil. Too much water will flush pesticides below the root zone and into groundwater.
“Understanding how IDP behaves in these soils is crucial,” said Uthman, the study’s lead author. “While we found that water moves one and a half to two times faster than IDP in sandy soils, the pesticide can still leach below the root zone under prolonged rainfall.”
<h5>The Research Approach</h5>
The team combined field experiments, laboratory column studies, and computer modeling to track water and pesticide transport. In the laboratory, they used saturated soil columns to test how IDP moved under fully soaked conditions. In the field, soil moisture was continuously monitored at multiple depths over nearly a year, including during major rainfall events such as Hurricane Ian. The WAVE computer model then simulated how water and IDP move through unsaturated sandy soils. (WAVE stands for Water and Agrochemicals in the Soil, Crop and Vadose Environment.)
“By pairing real-world measurements with advanced models, we captured both the complexity of Florida’s soils and the unpredictability of its climate,” Uthman said. “This dual approach provides a much stronger basis for recommending management practices to growers.”
To refine the models, the researchers ran more than 70,000 simulations. They used global search and optimization techniques to match field observations with predicted data.
<h5>Results and Impact</h5>
The study showed that IDP can move beyond the root zone after several hours of consistent rainfall. While water percolated faster, the pesticide still leached to depths of 45 to 60 centimeters within a week under field conditions. Topsoil layers with more organic carbon slowed pesticide movement. This suggests organic amendments, such as compost, could help keep IDP in the upper root zone, making it more available to trees. The WAVE model effectively reproduced both water flow and pesticide transport, offering a valuable decision-support tool for growers.
“Combining field data with advanced modeling helps us better understand when and how pesticides may move beyond the root zone,” said Davie Kadyampakeni, an associate professor in SWES and Uthman’s faculty adviser. “These insights can guide irrigation and soil management practices that protect both crop health and water quality.”
Moving forward, the researchers say more work is needed to refine pesticide modeling under real-world field conditions. That should give Florida citrus growers better guidelines to manage water and pesticide applications more sustainably.
