    Abstract: A new UV-Visible spectrophotometric method for determination of fungicide azoxysrtobin was developed. The method is based on the bromination of azoxystrobin to form dibromoazoxystrobin which react with Potassium iodide, Potassium iodate mixture in the presence of leucomalachite green (LMG) to form a bluish green colored complex. Characterization was done for the synthesis of bluish green colored complex by using UV-Vis spectrophotometer and FTIR methods. As a result, the UV-Visible absorption spectrum was observed at 615 nm. The limits of detection and limits of quantification were observed at 0.0019 µg ml-1 and 0.0059 µg ml-1 respectively. We have also studied the conformational and functional group (such as most characteristic band of O-H stretching frequency observed at 3346.49 cm-1, Bonding N-H symmetrical is 1645.50 cm-1, C=C bending is 691.07 cm-1, Symmetrical stretching C-N is 1493.13 cm-1 and 1404.70 cm-1, C-C stretching and other vibrational is 1059.74 cm-1). Involved in the complexation between azoxystrobin and bromination by FTIR method. This developed method has been successfully applied for the detection of azoxystrobin in various environmental samples. Beer’s law obeyed over the concentration range of 0.5-13 µg mL-1 in final solution volume of 10 ml. The reproducibility assessed by carrying out seven days replicate analysis of a solution containing 5 µg ml-1 of azoxystrobin in a final solution of 10 mL. The molar absorptivity of the colour system is 1.936×106 L mol-1 cm-1 and Sandell’s sensitivity is 0.800 ×10-4 µg cm-2. The relative standard deviation (RSD) for the absorbance value was found to be 1.9%. The suggested method is free from the interference of other toxicant agents. The analytical parameters were optimized and the method was applied to the determination of azoxystrobin in water, soil and food samples.

    Abstract: The present work describes a newly developed method for the spectrophotometric determination of cymoxanil in soil, water and vegetable samples. The detection of the target chemical substance is based on the reaction of cyanide released from the hydrolysed product of cymoxanil with potassium iodide-potassium iodate to form a blue-coloured complex in the presence of starch solution. This complex is water-soluble and shows maximum absorbance at 580 nm. For this complex, Beer's law is obeyed over the concentration range of 2-50 μg mL−1 with molar absorptivity 1.2×105 L mol-1cm-1 and Sandell’s sensitivity 1.0×10-3 µg cm-2. The reproducibility was assessed by carrying out seven days replicate analysis of a solution containing 10 µgmL-1 of cymoxanil in a final solution of a volume of 10 mL. The standard deviation and relative standard deviation for the absorbance value were found to be ± 2.9×10-3 and 1.6% respectively. The proposed method is free from the interference of other toxicants. The analytical parameters were optimized and the method was applied to the determination of cymoxanil in water, soil, and vegetable samples.

    Abstract: An organophosphorous insecticide monocrotophos is increasingly being utilized in agriculture to control insects on a broad range of crops. In this study a new reaction system using spectrophotometric method for quantitative determination of monocrotophos is proposed. The method is based on the bromination of monocrotophos to form dibromomonocrotophos which react with Potassium iodide-Potassium iodate mixture in the presence of leuco malachite green (LMG) to form a water soluble greenish blue colored complex. The change in absorbance as a criterion of the bromination reaction progress was followed spectrophotometrically. To obtain t he maximum sensitivity the effective reaction variables were optimized. The absorbance maximum was observed at 620 nm. Under optimized experimental conditions calibration graph was linear over the range of 10.0-60.0 µg. The molar absorptivity of the colored system is 3.66×104 L mol-1 cm-1 and sandell’s sensitivity is 0.25×10-2 µg cm-2. The calculated detection limit was 0.44 µg mL-1. The interfering effect of various species was also investigated. The present method was successfully applied to the analysis of monocrotophos in different environmental and water samples.

    Abstract: Simple and sensitive spectrophotometric scheme was described for the determination of fenvalerate in environmental samples. The scheme was based on the hydrolysis of 1 N of 5 mL NaOH to form cyanohydrin. The cyanohydrin is reacted with bromine and pyridine to form glutaconic aldehyde, which is then coupled with p-Dimethylaminobenzaldehyde to give yellow dye having maximum absorbance at 440 nm. Beer’s law is obeyed over the concentration range of 0.6- 6.2 µg in a nal solution volume of 25 mL. The molar absorptivity of the colored system is 3.84×104 L mol-1cm-1 and Sandell’s sensitivity is 2.4×10-3 µg cm-2. The reproducibility assessed by carrying out seven days replicate analysis of a solution containing 0.6 µg of fenvalerate in a nal solution volume of 25 mL. The standard deviation and relative standard deviation for the absorbance value were found to be ± 3.4×10-3 and 1.5% respectively. The proposed scheme is sensitive and free from the interference of other toxicants. The analytical parameters were optimized and the scheme was applied to the determination of fenvalerate in environmental samples.

    Abstract: Pesticides are designated mixture of substances for extenuating and destroying any group of pests such as insects and vegetation. Pymetrozine [6-methyl-4-[(E)-pyridin-3-ylmethylideneamino]-2, 5-dihydro-1, 2, 4-triazin-3-one] is a pyridine azomethine compound which represents a class of insecticide. A Spectrophotometric method has been developed on the modified Fujiwara reaction for the determination of pymetrozine. Pymetrozine directly reacts with chloroform the 45-500C turns out the violet color in the formation of Schiff’s Base (Glutaconic Aldehyde). In the present reaction, the violet color obtained is discharged with a few drops of acetic acid followed by the addition of p- nitro aniline reagent which gives yellow color dyes. The absorption maxima of yellow-colored dye measured at 430 nm. Beer’s law is obeyed over the range of 1 to 10 µg per 10 ml of pymetrozine. The molar absorptivity of the colored system is 1.38×105 L mol-1 and Sandall’s sensitivity is 1.0×10-3µg cm-2. This method is free from the interference of other interfering and can be successfully applied for the determination of various ecological samples.

    Abstract: Intention of this research was to develop an analytical technique for analysis of alphacypermethrin (ACYM). It is a pyrethroid insecticide used in agriculture for destroying harmful insects and for killing malaria vector as a public health program. To measure residues of the ACYM in some vegetable samples, a novel method is developed for determination of ACYM. Literatures reveal minimum information about the spectrophotometric determination of ACYM. When ACYM is brominated, it forms dibromoalphacypermethrin which reacts with potassium iodide and potassium iodate in the presence of starch to form blue color dye. The dye show highest absorbance at λmax = 625 nm. Parameters which effect on the reaction were studied and conditions were optimized. Linear calibration curve was obtained from 40 to 120 μg mL-1 ACYM and lower detection limit was 10 μg mL-1. This method was applied on some vegetables and fruit samples for the determination of ACYM.

    Abstract: Phyllanthus emblica is a deciduous shrub used in the Ayurvedic medicinesystem and has been reported to boost defense against ailments. The different parts of these plants are used to manage a large number of health conditions such as liver disease, heart disease, ulcers, anemia, humanoids, and other diseases. The ethanolic leaf extract of Phyllanthus emblica was evaluatedfor its anthelmintic activity against the Pheretima posthuman(Indian adult earthworm).The fresh leafextract of thesewith different concentrations (30 mg/ml, 60 mg/ml, and, 100 mg/ml) was tested in invitro, to investigate the paralysis and death times of worms.The ethanolic extract showed concentration-dependent anthelmintic activity at all doses. Normal saline served as the control group while albendazole (20 mg/ml) served as the reference medication. The Ethanolic Leaf Extract of Phyllanthus emblica was found to possess vermifuge (paralysis) and vermicidal (death) activity at all dose levels.
