Legislation Introduced for Growers Impacted by Freezes
U.S. Representatives Greg Steube (R-Fla.) and Darren Soto (D-Fla.) introduced the Temperature Endorsement for Multi-Peril Policies (TEMP) Act to protect farmers impacted by crop-damaging freezes. Rep. Steube proposes this legislation for inclusion in the 2023 farm bill. “This winter, a freeze caused significant damages to Florida’s citrus, sugarcane, ornamental plants, and many fruits and vegetables. Currently, specialty-crop insurance policies are expensive, leaving farmers with limited options …
Brazil Has Knowledge Needed to Manage HLB
Although a Fundecitrus researcher recently called the HLB situation in Brazil “alarming,” the organization says the industry has the knowledge needed to manage the disease. HLB is also known as citrus greening. “The management package exists and is efficient. The problem is that, in order to reduce costs, it is not applied rigorously, correctly and in an integrated manner,” said …
Growing Matters: Implementing Pollinator Protection Practices
The 2022 BeSure campaign from the Growing Matters Coalition is once again helping to support the implementation of practices focused on pollinator protection. “Pollinators have obviously taken a lead in the industry and how we can protect and steward that resource. This campaign is looking at how can we promote awareness for applications and protect pollinator safety out there,” said …
Assessing the Safety of a Water Distribution System
By Taylor O’Bannon, Matt Krug and Michelle Danyluk The U.S. Food and Drug Administration recently proposed changes to the pre-harvest Agricultural Water (Subpart E) section of the Food Safety Modernization Act Produce Safety Rule (PSR). Removing the annual water distribution system inspection is not one of the proposed changes. Rather, water testing for generic E. coli and developing a microbial …
A Challenging Harvest Season for Alico
The current citrus harvest season “has been a challenging one for Alico,” the company stated in a late March press release. “In addition to a harvest season that was anticipated to produce less fruit than in the prior year, many of the state’s citrus groves, including Alico’s citrus groves, were impacted by a freeze event in late January 2022.” Nearly …
Phosphorus Recommendations and Soil pH Amendments
By Kelly T. Morgan and Davie Kadyampakeni Most information provided in the 2020 3rd edition of Nutrition of Florida Citrus Trees is still sound for healthy citrus trees under Florida production conditions. Past information on nutrients, application methods, leaf and soil sampling, and irrigation scheduling are also effective for management of huanglongbing (HLB)-affected trees. However, research conducted since HLB was …
