Residual herbicides regularly used in conjunction with conservation tillage to produce corn ( L.) and soybean [ (L.) Merr] are often detected in surface water at concentrations that exceed their U.S. maximum contaminant levels (MCL) and ecological standards. These risks might be reduced by planting glyphosate-tolerant varieties of these crops and totally or partially replacing the residual herb...

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...

Article history: Received on: 21/11/2015 Revised on: 07/12/2015 Accepted on: 26/12/2015 Available online: 09/01/2016 The toxicological effects of herbicide Pretilachlor on photosynthesis, respiration and nitrogen assimilation of the unicellular cyanobacterium Synechocystis sp. PUPCCC 64 has been studied. Treatment of the test organism with Pretilachlor (10, 15 and 20 mg L -1 ) negatively affect...

The hypothesis that habitat restoration will provide for community reestablishment and the creation of habitat heterogeneity was examined with regards to the herpetofauna of longleaf pine sandhills in northwest Florida. The herpetofaunal response to restoration was examined in fire-suppressed, hardwood-dominated areas treated with (1) spring fire; (2) felling or girdling; or (3) a granular form...

The midge Chironomus tepperi was used in laboratory experiments to assess the relative toxicity of formulated molinate, clomazone, and thiobencarb, three herbicides used in Australian rice crops. Static bioassays were initiated with first-instar larvae at herbicide concentrations between 0.0625 and 2 times the anticipated field concentrations (AFCs) expected from the registered application rate...

Laboratory and field experiments were conducted to evaluate the effect of olive-mill waste (OMW) addition to a Mediterranean olive grove soil on sorption, persistence, and mobility of two herbicides which are simultaneously applied for weed control in olive groves: terbuthylazine (TA) and fluometuron (FM). Laboratory batch sorption experiments showed that OMW addition to the soil at rates of 5 ...

Aim. This work is devoted to the search for potential partners integrated application of flumioxazine in sunflower crops. herbicide an inhibitor protoporphyrinogen oxidase (PPO) weed plants. The resistance this class herbicides not yet common today, compared other classes. Therefore, aimed at de- veloping flumioxazine-based compositions that effectively prevent emergence herbicide-resistant bio...

this paper presents a method for generating a digital management map to apply cyanazine pre-emergence herbicide. the main objective was to develop a precision method to generate management maps for the variable rate application of herbicide to reduce the amount of herbicide applied and its adverse impact on the environment. first, local and utm coordinates of a field were determined using total...
