“…Lambda-cyhalothrin (LC) is a synthetic pyrethroid insecticide, with its chemical name as (RS)-alphacyano-3-phenoxybenzyl3-(2-chloro 3,3,3 trifluoropropenyl)-2,2, dimethyl cyclopropane carboxylate, introduced in 1988 [2]. Pyrethroid pesticides are highly active neurotoxic and have been mostly used in agricultural filed to control large number of insects [3].…”

“…The PH was also determined simply by a pH meter and other trace metals (Fe, Zn and Cu) using an Atomic Absorption Spectrophotometer (AAS), [10]. The cation ion exchange capacity of the metallic elements at neutral pH was determined by Titration after distillation [11] To conduct the adsorption study, 2,4,6,8,10,20,40,60,80, and 100 g/L were prepared and adsorption values determined at the UV-vis between 200 to 900 nm. The existence of the adsorption/desorption equilibrium of 2.0 g, 1.0 g, 0.5 g, 0.2 g and 0.1 g of the soil samples were investigated.…”

“…The use of Pesticides including Lambda-Cyhalothrin in livestock and crop farming have led to increased food security and livelihood in many developing countries though uncontrolled excessive use is hazardous to human life as well to the environment. LambdaCyhalothrin and other pesticides rapidly disappear upon application in the environment [2] Studies have proven that approximately 2-5% of applied pesticides go to targeted organisms and subsequently the rest end up in the environment [3]. Pesticide substrates in the environment undergo several chemical processes including oxidation, absorption, degradation, halogenations, transfer and other microbial actions [4] Transfer of pesticide residues away from the targeted sites through volatilization, spray drift, agricultural runoff, leaching, or crop removal is a major determining factor in assessing the overall environmental impacts of pesticides [5].…”

Lambda-Cyhalothrin is extensively used in agriculture, horticulture, and public health management in Kenya. The pesticide is effective against many vegetable pests, rice and other disease agents. The adsorption of L-Cyhalothrin onto sediments of Athi River was studied using UV-visible and the results were analyzed by fitting data into isotherm models including Freundlich and Dubinin-Radushvich plot to understand the environmental impacts of this pesticide. The models presented different numerical values but the results demonstrated similar characteristics. The study was aimed at determination of adsorption characteristics of L-Cyhalothrin on sediments from Athi River. Different masses of sediments were spiked with different concentrations of L-Cyhalothrin. The mixtures were shaken at varied times to reach equilibrium. The amounts of pesticide adsorbed were determined by analyzing the difference between the UVvisible Spectrophotometer data and the initial concentrations. Line Plots were used to determine other thermodynamic variables. Various isotherm models were used to explain the adsorption characteristics of the Lambda-Cyhalothrin. It stands out that Dubinin-Radushvich (D-R) with average R2: 0.935, 0.938 and 0.898 fitted best in this experiment while Freudlich R2: 0.783, 0.899 and 0.812 for all sediment samples, Upstream, Midstream, and Downstream, respectively. The spontaneity of the adsorption process was also realized in ΔG (Gibb's free energy) values as predicted by Freundlich. In both models, Midstream ∆G was negative (-) showing complete spontaneous characteristics. Also in Upstream, ∆G was negative (-) for Freundlich whereas Downstream ∆G was positive (+). Generally, adsorption capacity of Athi river sediments was low due to low mineral contents and total organic Carbon including other physicochemical properties specifically, textures, Nitrogen content including its temperature and moisture contents.

“…This class of insecticides has been widely used since 1970 to control a wide spectrum of agricultural and public health pests, such as thrips, aphids, beetles, flies, mosquitos and beetles. 30,33) We chose deltamethrin (Decis ® Evo, 2.42 g ai 100 g −1 , Bayer CropScience Italia, Viale Certosa 130, 20156 Milan, Italy) and lambda-cyhalothrin (Karate ® Zeon 1.5, 1.47 g ai 100 g −1 , Syngenta Italia, Via Gallarate 139, 20151 Milan, Italy), two of the most widely used pyrethroids. 30) Deltamethrin was reported to have negative effects on the growth of maize compared to untreated plants, 34) but no such effects are known for lambda-cyhalothrin.…”

Direct effects of insecticides on common ragweed-implications for natural enemy exclusion trials

Experimentally applying pesticides is an important method to assess the efficacy of weed biocontrol agents, but potential direct effects of the chemicals on plant performance are controversial or unknown. We assessed how three broad-spectrum insecticides applied in combination affect the performance of the widely invasive, crop-yield reducing, allergenic common ragweed (Ambrosia artemisiifolia L.) in an insect-free environment. Spraying insecticides had no significant effects on aboveground dry weight, seed and pollen output or pollen allergenicity, and only explained 1-8% of variation in these parameters. Our insecticide treatment can hence be applied to assess biocontrol impact on biomass and reproductive output of common ragweed. As our insecticide treatment delayed senescence, however, other methods of insect exclusion should be preferred when studying common ragweed phenology.
