Phytotoxicity of Profenofos 50% EC (curacron 50 EC) to Vigna radiata,L. seedlings: II. Studies on Biochemical Parameters

Abstract

Profenofos 50% EC (curacron 50 EC) is a hazardous pesticide commonly used in agriculture is also an important contaminant of environment.Its presence in biological system has gained importance due to bioaccumulation in food chain. The phyto-toxic effect of profenofos wasassessed based on the biochemical parameters (Shoot and Root) of seedlings (Amino acids, Protein, Sugar, DNA and RNA) of the test species,Vigna radiata,L. The concentrations of pesticide chosen were based on EC50 and are in the range of 0.02, 0.05, 0.08, 0.1 and 0.2 % ofprofenofos. The biochemical parameters like Amino acid, Sugar, DNA and RNA were significantly reduced with increase in pesticideconcentration whereas Protein concentration increased with the profenophos treatment. The increase in amino acid was more pronounced inShoot of the seedlings than root.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.12063 Int J Appl Sci Biotechnol, Vol. 3(1): 101-105

Morpho-Molecular Characterization of <i>Ditylenchus dipsaci</i> and Alternatives for Its Management in Green Onion <i>Allium fistulosum</i> Crops from Colombia

“…Although the treatment with the chemical product was effective in controlling D. dipsaci, the yield of the treated plants was similar to that of the absolute control, which suggests a phytotoxic effect of Cypermectrin and/or Profenofos, which has been reported in the past and related to the alteration of cell division processes, synthesis of amino acids and nucleic acids, as well as the reduction of the contents of photosynthetic pigments (chlorophyll) in plants [57] [58] [59] [60].…”

Side Effects of Some Pesticides Applied on Thrips Tabaci L. And Tetranychus Urticae (Koch) on Some Biochemical Contents and Enzyme Activities of Cucumber Leaf

“…Analysis and ANOVA indicates the statistical highly significance and the change in peroxidase activity in leaves were the tested compounds treatment dependent. The results were obtained by Chauhan et al (2013), Mishra et al (2015) and Ashrafi and Pandit (2016) who showed that the imidacloprid and profenophos treatments increased enzyme (catalase, peroxidase and polyphenol oxidase) activity. Homayoonzadeh et al (2020) studied imidacloprid and dichlorvos sprayed to control cucumber whiteflies on cucumber seedlings.…”

Ecotoxicity of Diazinon and Atrazine Mixtures after Ozonation Catalyzed by Na+ and Fe2+ Exchanged Montmorillonites on Lemna minor

“…This higher toxicity of ATR was already explained in terms of its molecular structure. The latter is specifically tailored for ATR to act as an herbicide unlike diazinon that rather exhibits insecticide features [ 28 , 29 , 30 , 31 ]. This EC50 value of ATR is slightly lower than that reported for L. minor but approximately twice lower as compared to that registered for other living species such as L. gibba (0.089 mg L −1 ) [ 25 , 32 , 33 , 34 , 35 ].…”
