Soil Humic Substances and Root Exudates: Key Factors Modulating Cadmium Mobility in Paddy Soils Under Organic Fertilization

Land Degradation &Development, EarlyView.
ABSTRACT Cadmium (Cd) contamination in paddy fields poses a high potential risk of environmental exposure. Organic fertilizer application can promote the efflux of rice root exudates, increase soil organic matter, and induce changes in Cd activity in rice fields.

Imidacloprid and Related Compounds: Structure and Water Solubility ofN-Alkyl Derivatives of Imidacloprid [PDF]

Bioscience, Biotechnology, and Biochemistry, 1998
An intramolecular hydrogen bond between NH•••O2N in insecticide, imidacloprid (1), and its nitromethylene analog 15 was proved by NMR and IR spectra. That electron delocalization over their planar moieties was disrupted by alkylation at the imidazolidine nitrogen atom is demonstrated by the hypsochromic shifts in UV and deshielding effect in NMR ...

Toxicity, Repellency, and Horizontal Transfer of Foam Insecticides for Remedial Control of an Invasive Drywood Termite, Cryptotermes brevis (Blattodea: Kalotermitidae)

BioResources, 2023
Laboratory tests were conducted to compare imidacloprid and fipronil foams against various criteria to determine the effect of the deposit conditions, exposure method, and exposure time on the toxicity, repellency, and horizontal transfer of selected ...

Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Assessing the potential for insecticide cross‐resistance to a novel insecticide in the Colorado potato beetle (Leptinotarsa decemlineata) using phenotypic and transcript expression analysis

Pest Management Science, EarlyView.
Phenotypic and transcriptional responses to imidacloprid and isocycloseram were examined across U.S. populations of the Colorado potato beetle, showing evidence of phenotypic cross‐resistance alongside population‐level variation in detoxification gene expression.

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Biodegradation of imidacloprid

, 2020
Imidacloprid (1-[(6-chloro-3-pyridinyl)methyl]-N-nitro-2-imidazolidinimine), a chloronicotinyl insecticide used to control biting and sucking insects, is very persistent in the soil with a half-life often greater than 100 days. Our objectives were to 1) discover, isolate, and characterize a single microbial species with the ability to degrade ...

Residues and Dietary Risk Assessment of Imidacloprid in Bamboo Shoot (Phyllostachys praecox), Winter Jujube (Ziziphus jujuba Mill. cv. Dongzao), Dendrobium officinale Kimura et Migo, and Fritillaria

Agronomy, 2023
The widespread use of pesticides poses significant risks to food and environmental safety. Imidacloprid is one of the most effective neuroactive neonicotinoid insecticides and is effective against a broad spectrum of piercing–sucking pests.

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

High Tolerance and Delayed Responses of Daphnia magna to Neonicotinoid Insecticide Imidacloprid: Toxicokinetic and Toxicodynamic Modeling.

Environmental Science and Technology, 2020
Species sensitivity to neonicotinoids has been shown to be highly variable among aquatic invertebrates. Toxicokinetic and toxicodynamic (TKTD) models were constructed to mechanistically elucidate the susceptibility of Daphnia magna to imidacloprid.
