Doctor in South Florida Sues to Block Hazardous Mosquito Spray

(Beyond Pesticides, July 11, 2017) South Florida resident Michael Hall, M.D., filed an emergency request in federal court last week to block Miami-Dade County’s continued use of the organophosphate insecticide naled to control mosquito populations. There have been two rounds of aerial naled applications in Miami-Dade this year. Widespread use of the chemical in efforts to control the transmission of Zika last year prompted protests from residents complaining of health effects from the spraying, and calls to focus on less toxic, alternative methods of mosquito breeding prevention and control. The present use of naled in Miami-Dade is not focused on Zika control, but addressing the native salt marsh mosquito, which does not transmit human diseases, but can be a significant nuisance in shoreline areas. According to WLRN, officials are no longer using naled for Zika control as the mosquito species that carries it, Aedes aegypti, usually stays well hidden under vegetation and shrubbery. A study released last year confirmed that the county’s use of naled did little to reduce mosquito populations. “Naled, a potent organophosphate adulticide applied aerially, produced a transitory suppression in Wynwood but lost efficacy after two or three applications. In Miami Beach, aerial application of naled produced […]

NOSB Decides on Organic Livestock, Delays Hydroponics Decision

(Beyond Pesticides, April 26, 2017) Last week, at its spring meeting in Denver, Colorado, the National Organic Standards Board (NOSB) voted unanimously to recommend that the Organic Livestock and Poultry Practices rule become effective immediately. This recommendation was originally made by the NOSB in 2011, and requires organic meat and poultry producers to allow animals to “exhibit natural behavior, such as the ability to sit, walk, stretch and stand without touching other animals or the sides of their pen, as well as having free and clear access to the outside.” Decisions were also made regarding a wide range of materials and practices, including synthetic additives in infant formula, mulch, sanitizers, and disinfectants. A decision on hydroponic growing methods and their eligibility for organic certification ultimately ended up being delayed again at the spring meeting, with no formal vote or action being taken. At the meeting, Beyond Pesticides maintained its position on hydroponics, aeroponics, bioponics and aquaponics methods, stating that it should not be considered eligible for organic certification. Organic production depends upon the “Law of Return,” which together with the rule “Feed the soil, not the plant,” and the promotion of biodiversity, provide the ecological basis for organic systems. These hydroponic […]

More Evidence Neonics Inhibit Social Behavior and Pollination Skills in Bumblebees

(Beyond Pesticides, January 10, 2017) Exposure to neonicotinoid (neonic) insecticides leads to a decrease in pollination frequency and fewer social interactions in bumblebees, according to research published by scientists from Harvard University and University of California, Davis. The study, released last year but presented this week at the Society for Integrative and Comparative Biology’s annual meeting, underscores the need for regulators and policy makers to eliminate use of these chemicals, not only to protect honey bees, but also wild pollinators like the bumblebee. While worker bumblebees (Bombus impatiens) divide their tasks within the colony in a similar manner to honey bees, their nests appear quite different than their more structured cousins. “Bumblebee nests are not the organized, beautiful geometry of the honeybee,” said James Crall, PhD candidate in Harvard’s Department of Organismic and Evolutionary Biology. Instead, “They’re more a hodge-podge of food and larvae in a pile in the middle of the nest space.” For their study, researchers placed four bumblebee colonies in a mesh enclosed area, tagged each bee, and observed them foraging on tomato flowers grown in a pollinator-excluding greenhouse (to ensure bees had freshly-opened flowers for pollination each day). After observing normal behavior, bees within each colony […]

NOSB Meets This Week, as Hydroponic Farmers Seek Formal Allowance to Use Organic Seal

(Beyond Pesticides, November 17, 2016) This week, the National Organic Standards Board (NOSB) is meeting in St. Louis to hear public comments on organic agricultural issues that will ultimately influence standards and processes. One major issue before the board is a motion on whether hydroponic and aquaponics operations can be certified organic. Farmers that practice hydroponic growing techniques are hoping to get the attention of the NOSB as they make an argument for their place in the certified organic industry, while others will be there to reject these arguments and uphold organic as soil-based agriculture. Despite a 2010 recommendation from the NOSB to prohibit allowing hydroponic production to quality as organic, USDA’s National Organic Program allowed organic labeling of the sector, which has experienced rapid growth in recent years. Typically, consumers have no way of knowing that the organic labeled prodeucts they are buying were grown organically. The NOSB is an advisory group, made up of 15 public experts, that makes direct recommendations to the U.S. Secretary of Agriculture on organic production, handling, and processing. In 2010, the NOSB recommended that farmers using hydroponic systems be ineligible for the organic certification. However, the National Organic Program (NOP) decided to ignore […]
