By Christopher Vincent Particle film is a useful tool to take the edge off stress to citrus trees caused by weather and HLB. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research over the past several years shows moderate concentrations of kaolin particle films cause trees to grow faster, suffer less water loss and keep leaves cooler, even …
By Sharpton Toussaint and Christopher Vincent Kaolin particle film is a promising grove management technique for pest control and growth enhancement. The optimal rates to use to improve water use and growth in citrus trees remain an important area of investigation. Citrus leaves are prone to water deficits because they transpire more water than the stems can supply. University of …
Researchers found use of kaolin particle film on trees reduced populations of HLB-spreading psyllids and delayed HLB infection. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor Christopher Vincent presented his research comparing red and white kaolin particle films with foliar insecticides during a recent UF/IFAS OJ Break webinar. According to Vincent, the particles of kaolin clay …
Managing the Asian citrus psyllid (ACP) that spreads citrus greening disease (HLB) has become a crucial task at the forefront of much research. One management option that has proven to reduce ACP populations while increasing tree growth and yield is particle film. During the 2020 virtual Florida Citrus Industry Annual Conference, University of Florida Institute of Food and Agricultural Sciences …
A pair of panel discussions during the citrus seminars at the Florida Citrus Show gave growers the opportunity to engage with experts on top-of-mind topics. BREEDER RECOMMENDATIONS The citrus seminar program started with a discussion among citrus breeders moderated by Flavia Zambon, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor at the Indian River Research and …
By Chris Oswalt Soil pH influences nutrient availability. This article considers the specific fate of nitrogen, phosphorus and potassium in soils with elevated pH values. The discussion also assumes that these effects would be similar to conditions in the wetted zone where micro-sprinkler irrigation has raised soil pH. NITROGEN Soil pH can affect several reactions involving nitrogen in the soil …
By Robin Koestoyo University of Florida citrus and vegetable researchers will present their latest scientific findings at the 78th Florida Citrus Show on April 3. A lineup of educational seminars will build on the show’s extraordinarily successful 77th show, organized by AgNet Media, an agricultural news communications leader. This year’s event will feature a tailgate-style trade show that includes breakfast …

California’s Citrus Research and Field Trials (CA-CRaFT) program is now accepting Cycle 2 applications from commercial growers. This initiative aims to showcase the efficacy of additional control measures against the Asian citrus psyllid (ACP). ACP is the carrier of the Candidatus Liberibacter asiaticus bacterium causing huanglongbing (HLB) disease in citrus. For Cycle 2, applications will be accepted until program capacity …
By Christopher Vincent, Yu Wang and Nabil Killiny Mild shade reduces stress, increases growth and yield, and may improve pest management under huanglongbing (HLB). It reduces high temperature and water stresses. Shade also may reduce HLB transmission by making trees less visible to Asian citrus psyllids (ACP). Shaded trees have less ACP, and shade appears to reduce the severity of …
By Christopher Vincent, Tripti Vashisth and Gillian Zeng Michalczyk Hurricane Ian harmed citrus trees in much of Florida, especially in areas where sweet oranges are grown. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are tracking the health of trees in groves around the state as they struggle to recover. Fall applications of gibberellic acid before the storm …
By Syed Bilal Hussain, Rachel Gearhart, G. Zeng Michalzcyk and Christopher Vincent Hurricane Ian in 2022 caused significant damage to Florida citrus groves. Even groves that experienced only Category 1 winds have begun to decline as the weather has warmed. Signs of canopy decline include branch dieback and leaf drop. Branches with new growth are also experiencing leaf drop. These …
Researchers will assess 20 to 30 Florida citrus groves impacted by 2022’s Hurricane Ian to learn lessons that will help growers in the future. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers Christopher Vincent and Tripti Vashisth and their teams will conduct the assessment. The research will be funded by a $280,000, one-year grant from the U.S. …

Give trees a bit of relief with frequent irrigation and kaolin particle film. By Christopher Vincent Hurricane Ian caused damage to orange trees, knocking fruit on the ground, twisting and breaking limbs, stripping leaves off trees and flooding soil. Although lots of damage was visible immediately, the after-effects will continue to rear their ugly heads in the months to come, …
By Lourdes C. Pérez Cordero Management of the Asian citrus psyllid (ACP) in the HLB era is incredibly important. This well-known insect can vector and facilitate the spread of the bacterium associated with HLB disease. Therefore, effective reduction of ACP populations can be beneficial for the citrus industry. But how exactly do we manage this pest? Unfortunately, there is not …
By Anirban Guha Heat stress could take a toll on citrus tree health and fruit yield. In Florida, the hot season lasts more than four months. Long, hot, oppressive summer days can heat up leaves and fruit and make the trees extra thirsty. Also, high soil evaporation, irregular rainfall and poor soil water-holding capacity can often lead to summer drought …
By Christopher Vincent Kaolin particle film is a non-toxic tool to reduce psyllids and increase tree growth. Particle films are nothing more than a suspension of solid particles that make a “film” on the leaves after they dry. They work mostly by reflecting light. Kaolin is the most common type of particle film because the clay is mined directly and …
