Photodegradation of Imidacloprid
Journal of Agricultural and Food Chemistry, 1999The photolytic decomposition of the insecticide imidacloprid (1) in HPLC grade water and of imidacloprid as the formulated product Confidor insecticide in tap water was studied using HPLC methodology. The structures of several degradates have been determined in aquatic medium, and the DT(50) values of imidacloprid and Confidor have been measured.

Biodegradation of imidacloprid: Molecular and kinetic analysis
Bioresource Technology, 2022Imidacloprid (C9H10ClN5O2) is the most widely used insecticide. Its persistence and toxic nature have caused a detrimental effect on living biota. Thus its removal from the contaminated environment has become imperative. The present study aimed to isolate bacterial species from pesticide-contaminated sites and assess their potential for biodegradation ...

CYP6DW3 Metabolizes Imidacloprid to Imidacloprid-urea in Whitefly (Bemisia tabaci)
Journal of Agricultural and Food Chemistry, 2023Bemisia tabaci has developed high resistance to many insecticides and causes substantial agricultural and economic losses annually. The insecticide resistance of whitefly has been widely reported in previous studies; however, the underlying mechanism remains little known.

Microbial hydroxylation of imidacloprid for the synthesis of highly insecticidal olefin imidacloprid
Applied Microbiology and Biotechnology, 2005Microorganisms that bring about the aerobic transformation of imidacloprid (IMI) were isolated and screened, and the microbial regio- and stereoselective hydroxylation of IMI was studied. Some bacteria and fungi transformed IMI to 5-hydroxyl IMI. Bacterium Stenotrophomonas maltophilia CGMCC 1.1788 resting cells transformed IMI into R-5-hydroxyl IMI at ...

Imidacloprid oxidation by photo-Fenton reaction
Journal of Hazardous Materials, 2008 This paper presents experimental results on the imidacloprid removal from wastewater using homogeneous photo-Fenton reactions illuminated with black light lamps. Multivariate experimental design was used to identify the effect of initial Fe(II) and H(2)O(2) concentrations on process performance.

Fatal intoxication with imidacloprid insecticide
The American Journal of Emergency Medicine, 2008Imidacloprid [1-(6-chloro-3-pyridylmethyl)-N-nitroimidazolidin-2-ylideneamine, CAS 138261-41-3] belongs to a relatively new class of insecticidal chemistry, the chloronicotinyl neonicotinoid compounds. Animal studies indicate relatively low toxicity to mammals. Despite wide usage in some countries, the understanding of human poisoning is quite limited.

Persistence and Metabolism of Imidacloprid in Rice
Bulletin of Environmental Contamination and Toxicology, 2014Imidacloprid is a systemic insecticide which gives effective control of plant and leaf hoppers in rice. The persistence and metabolism of imidacloprid in paddy leaves, rice grains, bran, straw and husk were studied following two applications of imidacloprid (Confidor 17.8 SL) @ 20 and 80 g a.i. ha(-1) at an interval of 10 days.

Imidacloprid poisoning: a case report
The American Journal of Emergency Medicine, 2009Imidacloprid is a systemic, chloronicotinyl insecticide. It is generally considered nontoxic to humans based on available literature. Its effects are mediated through acetylcholine receptor blockade. We report a patient with such poisoning who had respiratory arrest, for which he had to be mechanically ventilated, and who subsequently recovered.

Photochemistry of Imidacloprid in Model Systems
Journal of Agricultural and Food Chemistry, 2008The photochemical behavior of the neonicotinoid insecticide imidacloprid was studied with regard to different chemical environments. Different model solvents simulated the structure moieties mainly occurring in waxes and cutin of the plant cuticle. Cyclohexane and cyclohexene substituted saturated and unsaturated hydrocarbon chains, whereas ethanol and

Neonicotinoids are a popular class of pesticides around the world and have been shown to bind both insect and mammalian nicotinic acetylcholine receptors (nAChRs). Imidacloprid (IMI), is amongst the most commonly used neonicotinoids in agriculture and domestic, non-industrial, applications but shows strong toxic effects in many organisms.
