Macropore flow is a key factor determining pesticide fate, but models accounting for this process need parameters that cannot be easily measured. This study was conducted to investigate the use of inverse techniques to estimate parameters controlling macropore flow and pesticide fate in the dual-permeability model MACRO. Undisturbed columns were sampled at three landscape positions (hilltop, sl...
Perennial broadleaves such as dandelion (Taraxacum officinale G.H. Weber ex Wiggers) and white clover (Trifolium repens L.) are known to be pervasive weeds in stands of maintained turfgrasses. The use synthetic herbicides is the most common effective method control for these weeds. As pesticide European countries, Canada, United States becoming more scrutinized, identification alternative weed ...
Occupational exposures to pesticides may increase parental risk of infertility and adverse pregnancy outcomes such as spontaneous abortion, preterm delivery, and congenital anomalies. Less is known about residential use of pesticides and the risks they pose to reproduction and development. In the present study we evaluate environmentally relevant, low-dose exposures to agrochemicals and lawn-ca...
Pesticides applied to turf grass have been detected in surface waters raising concerns of their effect on water quality and interest in their source, hydrological transport and use of models to predict transport. TurfPQ, a pesticide runoff model for turf grass, predicts pesticide transport but has not been rigorously validated for larger storms. The objective of this study was to determine Turf...
This invasive plant management study focuses on the treatment of younger and older seedproducing black cherry (Prunus serotina Ehrh.) individuals. We injected trees applied bark to thinner saplings in 2018. Over two vegetation periods, we studied effect 11 herbicides ranked treatments based their introduced foliage loss sprouting. In trunk injection experiment, most effective was a combination ...
