Weeds on Missouri Cropland Found To Be Resistant to Six Different Herbicides  (Beyond Pesticides, August 2, 2018) 'Weed scientists from the University of Missouri (UM) have just published evidence of a water hemp population resistant to six different herbicides. The study is sending shock waves throughout the chemical-intensive agricultural community, particularly in light of the plant’s resistance to 2,4-D.'  This woud certainly affect the effectiveness of 'Enlist Duo, developed by DowDupont in an attempt to address widespread weed resistance to glyphosate. Enlist Duo is an herbicide containing both glyphosate and 2,4-D, and is intended to be sprayed only on crops genetically engineered (GE) to tolerate exposure to both chemicals. However, with growing reports like this, many farmers may begin to rethink their approach.'

Lice Found Resistant to Common Insecticide Treatment  (Beyond Pesticides, August 20, 2015) Just as children go back to school, research finds that lice in 25 of 30 states in a U.S. study have developed resistance to common over-the-counter treatments like permethrin, calling into questions the justification for exposing children to a neurotoxic and carcinogenic pesticide and elevating the need to consider nontoxic alternatives....Classified as a synthetic pyrethroid insecticide, permethrin is “likely carcinogenic” and a suspected endocrine disruptor, immunotoxic, neurotoxic, and highly toxic to fish, aquatic animals, and bees. Dr. Yoon and his colleagues describe the threefold mutations that lice have developed over time due to the constant use of synthetic pyrethroid insecticides. This new finding builds on his team’s previous research, which found that 99.6% of lice are resistant to chemical treatment, adding weight to the fact that chemical treatments not only are unnecessary given effective least-toxic alternatives, but also are not able to provide the lice control that manufacturers claim.
