Pesticide safety educators have turned to online delivery to reach a wider applicator audience and to adapt to the impacts of the COVID-19 virus. Microsoft® Teams and Zoom have been the most widely used among this group. This article discusses these platforms and some of the unique features that can be used to ensure that virtual training and applicator recertification are legal, ethical, and ultimately successful. The authors conclude that distance training will likely be part of the new norm in pesticide training.

This study investigated numerous factors influencing the removal of carbaryl or permethrin from various types of clothing. These factors included application rate (1X or 9X), washing machine type (full-fill agitator or high efficiency), clothing type (blue jeans, work shirt, T-shirt, or cotton/polyester blend T-shirt), and drying method (electric dryer or clothesline). Additionally, this study examined transference to baby Onesies┬« during laundering and assessed the role of Ultraviolet-B (UV-B) exposure in reducing residues for articles dried on clotheslines.  Contamination inside washing and drying machines and pesticide levels in wastewater were also examined. The results indicated that both washing machine types were effective at removing carbaryl and permethrin from the clothing. Among the different fabric types, blue jeans consistently retained more residues than other clothing types used in the study. Transference of pesticide to the Onesies┬« occurred with all pesticides at both rates, indicating pesticide-contaminated clothing should be laundered separately from all other laundry, including other work clothes or family clothes. Based on the findings of this study, we provide safety recommendations for applicators and laundering guidelines for effectively decontaminating clothing.
