Despite the higher domestic production, …
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).
