Protect Trees With Particle Films

Daniel CooperHLB Management, Tip of the Week, Weather

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 …

Help Trees Weather Heat With Particle Film

Josh McGillTip of the Week, Weather

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 …

Kaolin Particle Film Reduces HLB Pressure

Tacy CalliesHLB Management

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 …

Kaolin Particle Films for Citrus Under HLB Pressure

Tacy CalliesHLB Management

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 …

How to Help Trees Recover From High Winds

Daniel Cooperhurricane, Irrigation, Tip of the Week

By Christopher Vincent Hurricane Helene’s path spared most of the citrus industry the kind of trouble that Hurricane Ian brought back in 2022, but Ian taught us some important lessons you can use if your trees were hit by high winds. WIND SPEED MATTERS Trees impacted by Category 3 winds were mostly defoliated, with major limbs broken and near 100% …

Psyllid Nanopesticide Developed in Brazil

Daniel CooperBrazil, Pesticides, Psyllids

In Brazil, a more effective and sustainable insecticide for HLB-spreading psyllids was developed by Embrapa (Brazilian Agricultural Research Company) in partnership with the Institute of Chemistry of the State University of Campinas (Unicamp). The work resulted in a controlled-release system of the insecticide thiamethoxam molecule. Encapsulation was performed in polymeric nanoparticles, structures more than 80,000 times smaller than the thickness …

The Effect of Soil pH on Nutrient Availability

Daniel CooperNutrition

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 …

California’s CRaFT Accepting Cycle 2 Applications

Daniel CooperCalifornia Corner, Psyllids

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 …

Increase Yield With Shade

Josh McGillProduction, Tip of the Week

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 …
