Pesticide Labeling: Protection of Pollinators

On May 29, 2015, the EPA published its Proposal to Mitigate Exposure to Bees from Acutely Toxic Pesticide Products. This seven-page fact sheet outlines the highlights from this policy and its proposed restrictions, which would prohibit applications of pesticide products that are acutely toxic to bees during bloom where honey bees are known to be present under contract for pollination services.

Cucurbit downy mildew is a major disase that affects over 40 species of cucurbits, like watermelon, muskmelon, cucumber, squash, and pumpkin. The classic sign of the disease is the presence of dark sporangia, a structure that holds developing spores, on the underside of infected leaves. As the disease progresses, it may lead to large necrotic areas that cause defoliation and a reduction of yield and marketable fruit. This nine-page fact sheet describes the symptoms and signs, epidemiology and disease cycle, host range and pathotypes, and the ways to manage cucurbit downy mildew. Written by Mason J. Newark, Mathews L. Paret, Nicholas S. Dufault, Pamela D. Roberts, Shouan Zhang, Gary E. Vallad, Josh Freeman, and Gene McAvoy, and published by the Plant Pathology Department.

HS1156 Review of Nutrient Management Systems for Florida Vegetable Producers

HS1156, a 17-page white paper from the UF/IFAS Vegetable Fertilizer Task Force, identifies differences between actual fertilization practices and UF/IFAS fertilizer recommendations, especially for vegetables grown with subsurface (Central and South Florida) and overhead (Miami-Dade County) irrigation. The recommendations of the VFTF aim at bridging the gaps between science-based results and the diversity in production systems found in the Florida vegetable industry. Includes references. Published by the UF Department of Horticultural Sciences, April 2009.
