Molecularly imprinted polymers for dimethoate recognition were synthesized by the precipitation polymerization technique using methyl methacrylate (MMA) as the functional monomer and ethylene glycol dimethacrylate (EGDMA) as the cross-linker. The morphology, adsorption and recognition properties were investigated by scanning electron microscopy (SEM), static adsorption test, and competitive ads...

The persistence patterns of dimethoate and profenofos in fruits of tomato and cucumber and elimination of their residues through washing or home processing methods were studied. Residues were determined by gas liquid chromatography. Results showed that, the consumable safety time was found to be 10, and 14 days after application on tomato and cucumber. This was found to be enough to reduce the ...

This study presents the results of research concerning the effect of single and combined application of pyrantel tartrate and dimethoate on selected antioxidative enzymes: catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx), in rat erythrocytes. Pyrantel tartrate was applied twice, at a dose of 85 mg/kg bw at a two week interval, i.e. on day 14 and 28 of the experiment, ...

The recent spread of the African citrus psyllid, Trioza erytreae, one vectors devastating disease, Huanglongbing (HLB), to parts mainland Europe has created considerable concern. In this study, we show efficacy several insecticides with varying modes action on different developmental stages T. erytreae. laboratory trials, spinetoram caused highest mortality in erytreae eggs (between 80 and 90%)...

background:organophosphates are commercially available agrochemicals for pest control, but may be abused for deliberate self-poisoning. we report a case of suicidal ingestion of dimethoate, a moderately toxic organophosphate insecticide, which can cause refractory hemodynamic instability, and the successful use of methylene blue (mb) for counteracting this complication. case presentation: an un...

Dimethoate, a broad spectrum OP insecticide is a potential toxic pollutant, adversely affecting the fauna of aquatic ecosystem. The aim of present study was to assess the acute toxicity of dimethoate on fingerlings of common carp, Cyprinus carpio. The fingerlings were exposed to dimethoate to determine LC values for 24, 48, 72 and 96 h and to study the behavioural alterations. The mortality dat...

For the elucidation of effects of a pesticide on life-cycle parameters of arthropods, applicable in the development of ecotoxicological test procedures with soil living animals, attention was drawn to body growth, which has previously been described as a sensitive parameter in Collembola. Body growth of the following three soil-dwelling arthropods was studied under the influence of dimethoate: ...

With a view to study the leaching potential and consequently surface and ground water contamination, the adsorption of dimethoate on five soils of different characteristics has been carried out by using a batch equilibrium technique. A spectrophotometric methodology based on the reaction of thioglycolic acid, formed from microwave assisted alkaline hydrolysis of dimethoate, with carbon disulfid...

The topical toxicities of five commercial grade pesticides commonly sprayed in apple orchards were estimated on adult worker honey bees, Apis mellifera (L.) (Hymenoptera: Apidae) and Japanese orchard bees, Osmia cornifrons (Radoszkowski) (Hymenoptera: Megachilidae). The pesticides were acetamiprid (Assail 30SG), λ-cyhalothrin (Warrior II), dimethoate (Dimethoate 4EC), phosmet (Imidan 70W), and ...
