Bugs Under the Covers

Josh McGillIPCs, Pest Management

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 …

Improving Yield Safety of Glyphosate

Josh McGillTip of the Week, weeds

By Ramdas Kanissery Florida citrus growers face weed management problems throughout the year because of conditions that favor rapid weed growth in groves. A weed-free tree row is desired in a citrus grove to minimize weed competition with trees. Hence, chemical weed control using post-emergent, systemic herbicides like glyphosate has become a vital production practice in the Florida citrus industry. …

CUPS Weather Hurricane Ian Well

Josh McGillCUPS, hurricane

In the search for ways to survive citrus greening, some growers have chosen the citrus under protective screen (CUPS) system as their solution. While CUPS can be costly to construct, it has proven to effectively prevent the deadly disease. But some have asked if the structures would hold up in extreme weather and adequately protect the trees. Hurricane Ian helped …

The Essential Elements of Reset Management

Josh McGillplanting, Tip of the Week

By Mongi Zekri For maximum efficiency of a grove, it is essential that every location is occupied by a tree and that every tree is healthy. Prompt replacement of dead and declining trees means higher average long-term returns from the grove. If the declining trees remain in the grove, they keep getting weaker and yield less fruit each year. Therefore, …
