Field tests were conducted to evaluate the effect of Spodoptera litura (Fab.) nuclear polyhedrosis virus (NPVS) alone and in combination with endosulfan and neemarin (neem seed kernel extract) against S. litura in cabbage. Treatment with NPV-S (500 LE/ha) + Endosulfan (625 ml/ha) was better in reducing the larval population and increasing yield than other treatments. However, considering cost b...

An extraction method based on matrix solid phase dispersion (MSPD) and high performance liquid chromatography with UV detection for quantification of two widely used pesticides (Malathion and α-Endosulfan) in Khazar rice from north of Iran were investigated. The ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...

In Northern Benin, insecticides are used for cotton production. These can be easily transferred to water ponds close fields. To monitor levels in water, sediments and fish samples from ponds, a GC–MS analytical method was developed detect residues of endosulfan, DDT its parent compounds, isomers HCH, pyrethroids chlorpyrifos. addition, the influence storage conditions sample on pesticides deter...

Endosulfanis metabolized to a single metabolite, endosulfan sulfate, in pooled human liver microsomes (Km 9.8 M, Vmax 178.5 pmol/mg/min). With the use of recombinant cytochrome P450 (P450) isoforms, we identified CYP2B6 (Km 16.2 M, Vmax 11.4 nmol/nmol P450/min) and CYP3A4 (Km 14.4 M, Vmax 1.3 nmol/nmol P450/min) as the primary enzymes catalyzing the metabolism of endosulfan, although CYP2B6 had...

The effect of the pesticide endosulfan on predator-prey interactions between catfish and Schistosoma host snails was assessed in static tank experiments. Hybrid catfish (Clarias gariepinus × C. ngamensis) and Bulinus globosus were subjected to various endosulfan concentrations including an untreated control. The 48- and 96-h LC50 values for catfish were 1.0 and <0.5 µg/L, respectively, whereas ...

Organochlorine (OC) pesticides have been extensively used for pest control in agriculture and against malaria vectors in the region of Soconusco, Chiapas, in southern Mexico. Our study aimed to identify whether the inhabitants of four Soconusco communities at different locations (i.e., altitudes) and with different history of use of OC pesticides, have been similarly exposed to residues of thes...

Abstract—In the present study, presence of endosulfan, imidacloprid, carbendazim, in the soil /vegetables/cereals and water samples was observed in agriculture fields of Uttarakhand. In view of biodegradation of these pesticides, 9 bacterial isolates were recovered from the soil samples of the fields which tolerated endosulfan, imidacloprid, carbendazim from 100 to 200 μg/ml. Three bacterial co...

BACKGROUND In South Africa there is little data on environmental pollution of rural water sources by agrochemicals. METHODS This study investigated pesticide contamination of ground and surface water in three intensive agricultural areas in the Western Cape: the Hex River Valley, Grabouw and Piketberg. Monitoring for endosulfan and chlorpyrifos at low levels was conducted as well as screening...
