Competitive Sorption between Imidacloprid and Imidacloprid-urea on Soil Clay Minerals and Humic Acids

Journal of Agricultural and Food Chemistry, 2002
Soil organic matter and clay minerals are responsible for the adsorption of many pesticides. Adsorption and competitive sorption of imidacloprid on clay minerals and humic acids (HA) were determined using the batch equilibration method. The sorption coefficient of imidacloprid on humic acids was significantly higher than that on Ca-clay minerals ...

Quantification of Imidacloprid Uptake in Maize Crops

Journal of Agricultural and Food Chemistry, 2005
The systemic imidacloprid is one of the most used insecticides in the world for field and horticultural crops. This neurotoxicant is often used as seed-dressing, especially for maize, sunflower, and rape. Using a LC/MS/MS technique (LOQ = 1 microg/kg and LOD = 0.1 microg/kg), the presence of imidacloprid has been measured in maize from field samples at

Imidacloprid poisoning.

The Journal of the Association of Physicians of India, 2012
Imidacloprid is newer systemic insecticide, a nicotine analogue, acts on the nervous system. Patient can present with variable manifestations like irritability, labored breathing, emaciation, twitching and delirium. Here we report a case presented with sever neuropsychiatric symptoms with respiratory failure following self ingestion of poison.

Efficacy of imidacloprid, imidacloprid/permethrin and phoxim for flea control in the Mustelidae (ferrets, mink)

Parasitology Research, 2005
Farmed mink (Mustela vison), a close relative of the domestic ferret (Mustela putorius furo), naturally infested with the squirrel flea (Ceratophyllus sciurorum) were included in a study to investigate three compounds for flea control. The test products were imidacloprid in a 10% (w/v) solution, an imidacloprid 10% (w/v)/permethrin 50% (w/v) solution ...

Imidacloprid: Toxicology and Metabolism

1999
Imidacloprid (Figure 1) is the first active ingredient of the chemical class of nicotinoid insecticides to reach the market. Toxicological information on this class of substances is nearly nonexistent in open literature. Only limited toxicological information on the structurally related compound nitroguanidine is available, and it indicates no critical

Transport of Imidacloprid in Soils

Soil Science, 2010
Knowledge of the transport patterns of chemicals applied to soils is essential for environmental assessment of potential leaching to groundwater supplies. In this study, the mobility of imidacloprid applied to soils with different properties was investigated.

Distributions of imidacloprid, imidacloprid‐olefin and imidacloprid‐urea in green plant tissues and roots of rapeseed (Brassica napus) from artificially contaminated potting soil

Pest Management Science, 2016
AbstractBACKGROUNDImidacloprid‐urea is the primary imidacloprid soil metabolite, whereas imidacloprid‐olefin is the main plant‐relevant metabolite and is more toxic to insects than imidacloprid. We artificially contaminated potting soil and used quantitative UHPLC‐QqQ‐MS/MS to determine the imidacloprid, imidacloprid‐olefin and imidacloprid‐urea ...

Fipronil and imidacloprid reduce honeybee mitochondrial activity

Environmental Toxicology and Chemistry, 2014
Abstract   Bees have a crucial role in pollination; therefore, it is important to determine the causes of their recent decline. Fipronil and imidacloprid are insecticides used worldwide to eliminate or control insect pests.

Persistence and Metabolism of Imidacloprid in Rice

Bulletin of Environmental Contamination and Toxicology, 2014
Imidacloprid 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.

Application of TNB in dual photo‐controlled release of phenamacril, imidacloprid, and imidacloprid synergist

Photochemistry and Photobiology
AbstractPesticides can improve crops' yield and quality, but unreasonable applications of pesticides lead to waste of pesticides which are further accumulated in the environment and threaten human health. Developing the release of controlled drugs can improve the utilization rate of pesticides.
