ABSTRACT Fenoxaprop-p-ethyl is a selective grass herbicide that if registered will provide winter wheat growers with an additional weed control option. Field experiments were established in the fall of 2011, 2012 and 2013 at Ridgetown and Exeter, Ontario, to determine the sensitivity of four market classes of winter wheat [Soft white winter wheat (SWWW), soft red winter wheat (SRWW), hard white winter wheat (HWWW) and hard red winter wheat (HRWW)] to 1X and 2X fenoxaprop-p-ethyl/safener at early-(EPOST) or late-post emergence (LPOST) application timings. Fenoxaprop-p-ethyl/safener applied LPOST at 1X and 2X the manufacturer’s proposed label rate caused 4% and 5% injury 1 week after application (WAA), respect...

ABSTRACT Methylphenidate (MPD), known as Ritalin, is a common drug prescribed for those diagnosed with Attention Deficit Hyperactivity Disorder (ADHD).There are reports that many MPD users consume alcohol, resulting in toxic effects and hospitalization. The goal of this study was to investigate the effects of ethanol in rats concomitant with acute and repetitive MPD exposure. Rats were divided into four groups, control (saline), 0.6 mg/kg MPD, 2....

ABSTRACT There is limited information on the sensitivity of dry bean to dimethenamid-p, saflufenacil and a preformulated mixture of dimethenamid-p/saflufenacil. Field trials were conducted at Exeter and Ridgetown, ON, Canada in 2012 and 2013 to evaluate the tolerance of four market classes of dry bean to dimethenamid-p, saflufenacil and dimethenamid-p/saflufenacil applied preemergence (PRE) at the 1X and 2X manufacturer’s recommended rate in soybean. Dimethenamid-p, saflufena...
