Abstract Late watergrass [ Echinochloa phyllopogon (Stapf) Koss.] has evolved multiple-resistance (MR) to herbicides in many areas worldwide and scientists wonder if this resistance imposed fitness cost or advantage on the resistant biotypes. As of weed also been recorded Greece, one susceptible (S), with ALS (penoxsulam, bispyribac, imazamox nicosulfuron + rimsulfuron) ACCase-cyhalofop (MRAC) ...

Abstract Late-emerging summer annual weeds are difficult to control in dry bean production fields. Dry is a poor competitor with weeds, due its slow rate of growth and delayed canopy formation. Palmer amaranth particularly season-long emergence resistance acetolactate synthase (ALS)-inhibiting herbicides. growers rely on PPI preemergence residual herbicides for the foundation their weed program...

Twelve field trials were conducted over a three-year period (2010, 2011, 2012) at different locations in southwestern Ontario, Canada to compare various two-pass weed management strategies in glyphosate-resistant corn for crop injury, weed control, environmental impact, corn yield and profit margin. No visible injury resulted from the herbicide treatments evaluated. One early postemergence (EPO...

in this study, the effect of some toxic organic chemicals on mogan lake has been investigatedusing the aquatox model. the unique property of the model includes the sub ecotoxicological modelwhen compared to the other water quality models. the ecosystem model aquatox, which is one of the fewgeneral ecological risk models that represents the combined environmental repercussions and effects of tox...

efficacy of many herbicides to control broad- and narrow-leaf weeds (grass weeds) in tobacco fields of mazandaran and guilan provinces was investigated. the experiment was randomized complete blocks design in four replications and the following treatments: eptam (eradicane 82% ec) at 6 l.ha-1 which incorporated pre-planting (ppi), trifluralin (treflan 48% ec) at 2 l/ha ppi, cycloate (roneet 72....
