A recently synthesized herbicide Aquathol K was tested on the water weed Hydrilla verticil/ata. Results from the laboraoty tests indicated that Aquathol K with concentrations ranging from 1.0 mg/l to 2.0 mg/l can kill this weed. EVidently, 100% injury was achieved within 10 days for the plants treated with the highest concentration., 2. 0 mg/l of Aquathol K. The rate of 100% injury was recorded...

CONTEXT Quizalofop-p-ethyl is an often applied, slightly toxic herbicide for which no severe toxicity has been reported in humans. CASE PRESENTATION We present the case of a farmer exposed to quizalofop-p-ethyl who presented with obstructive cholestasis. A complete workup disclosed no other cause of liver pathology, but liver biopsy established drug-induced hepatotoxicity. The patient was tre...

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...

Abstract Environmental conditions surrounding herbicide applications are known to affect weed control and crop response. Variable levels of rice injury caused by florpyrauxifen-benzyl have been observed across cropping systems environmental conditions, warranting research in which single management strategies isolated understand the effect each factor on subsequent reductions growth. A field st...

INTRODUCTION Pesticide poisoning is an important public health problem worldwide. The study aimed to determine the risk of all-cause and cause-specific inpatient mortality and to identify prognostic factors for inpatient mortality associated with unintentional insecticide and herbicide pesticide poisonings. METHODS We performed a retrospective cohort study of 3,986 inpatients recruited at hos...

Herbicide carryover injury to rotational crops can vary in severity depending on the influence of soil properties herbicide bioavailability. Greenhouse bioassays were conducted with soybean, radish, and canola evaluate differences bioavailability three herbicides risk, atrazine, mesosulfuron-methyl, topramezone. Bioassays varying regional types nine treatment rates including a control. Plant vi...

Plants are frequently exposed to natural and synthetic toxins such as heavy metals, allelochemicals, organic pollutants, and pesticides. Consequently, plants must mount specific and coordinated defense mechanisms for survival under adverse growing conditions (Zhang et al., 2007). One such mechanism is the capability for metabolizing organic compounds from abiotic origin (xenobiotics). Extensive...

Green pigweed [Amaranthus powellii S. Wats.] is a competitive, annual, broadleaf weed that can significantly reduce soybean yield due to rapid early growth and biomass production. As consequence of green pigweed’s high competitiveness with crops, the species generally managed use herbicides; this may, however, lead selection resistance. A biotype resistance MCPA, mecoprop, dichlorprop-p, aminoc...

the lack of herbicides for broadleaf weed control is one of the most important challenges of chickpea production in iran. field experiments were conducted in lorestan, kermanshah, east and west azerbaijan to evaluate weed control and chickpea response to application of some herbicides in 2006. there were four replications at each site and treatments were arranged in a randomized complete block ...
