Chinese researchers have developed a nanoparticle-based formulation that combines an insecticide and a plant-derived repellent to provide longer-lasting control of HLB-spreading Asian citrus psyllids (ACP). An article about their study, published in Nanomaterials, explores a way to extend pesticide effectiveness while reducing damage to citrus leaves. The article was written by Wenhua Rao, Qianying Li, Kaidi Wang, Chao Shen, Guocheng …
Preharvest silicon (Si) applications, when combined with postharvest salicyclid acid (SA), may increase W. Murcott mandarin fruit size, according to research from Ege University in Türkiye. The study, published in the Ege University Faculty of Agriculture Journal, examined whether the Si and SA applications could help maintain mandarin quality during extended cold storage. The authors are İzzet Atakan Erdallı, Fatih …
By Tripti Vashisth, Mary Sutton and Taylor Livingston Author’s note: This Tip of the Week applies to HLB-affected sweet oranges in Florida. Preharvest fruit drop remains a major concern for HLB-affected sweet oranges.

Plant growth regulators (PGRs) could give citrus growers another tool for managing vigorous trees, reducing pruning needs and potentially improving production efficiency, according to a review of decades of citrus research. The review — “Managing Citrus Canopy Growth for Higher Productivity: A Review of Plant Growth Regulator (PGR) Applications” — was published Sept. 8 in Horticulturae. The authors are Kare …
By Christopher Vincent and Rashmi Kumari Florida summers come with intense sunlight, high temperatures and frequent rain. Just as people use sunscreen to protect exposed skin from intense sunlight, plants can benefit from a protective coating on exposed leaf and fruit surfaces. One way to provide this protection is by spraying a kaolin clay particle film on the tree. Although …
According to a September 2026 Rabobank report, the current environment for Brazilian orange juice (OJ) remains challenging for both farmers and the industry, with prices still low but starting to show some slightly positive signs. It reported that spot orange prices for the industry increased from BRL 25/box (approximately $4.30/box in U.S. dollars) in May to BRL 31/box (approximately $6.03/box …
Psyllid capture rates in São Paulo and the Triângulo/Southwest Minas Gerais region of Brazil rose sharply during the second half of August. The average jumped from 1.3 psyllids per trap in the previous two-week period to 6.13 psyllids per trap — a 372% increase. This spike serves as a warning regarding management of the greening-spreading psyllid, particularly during a time …
Chilli thrips’ damage in Florida citrus under protective screen (CUPS) should motivate growers to manage weeds more effectively. Lauren Diepenbrock, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor and entomologist, shared that advice during this year’s Citrus & Specialty Crop Expo in Fort Myers, Florida. Diepenbrock said chilli thrips feed on citrus trees but they also …

By Noor Ul Basar, Davie Kadyampakeni and Muhammad Adnan Shahid As citrus trees transition into the fall season, the nutrient demand of the trees will change. Therefore, nutrient application should be adjusted accordingly. NITROGEN Applying nitrogen (N) beyond October through December encourages tree canopy development at the expense of fruit yield and should be avoided. Excessive application of N in …
Despite a slowdown in Brazil’s citrus greening incidence growth rate in 2026, the severity of the disease continues to climb in trees remaining in the field, according to Fundecitrus’ annual citrus disease survey.
