“…The wide use of monocrotophos in agriculture leads to groundwater and surface water contamination causing neuro and genotoxicity of various organisms [10]. However, fatal dermal toxicity of OP is rarely reported [11]. Mortality associated with OP poisoning was 25% of which, the majority of deaths noted due to delay in discovery and transport of the patient to the hospital and due to respiratory failure [12].…”

Organophosphate (OP) poisoning is more common in developing countries such as India. Here, we report a case of self-inflicted oral OP poisoning (monocrotophos) by an adolescent male patient who presented to the emergency department of a tertiary care hospital with tachycardia and frothing without seizure episode (non-linear presentation in OP poisoning). Based on the evidence of consumption of OP compound, the management of the patient went as planned and guarded with i.v. administration of pralidoxime and atropine. Gastric lavage was done soon after the patient came to the hospital and was admitted to the Intensive care unit for 5 days and in the general ward for the next 24 h. The patient was discharged from the hospital in a hemodynamically stable state after 6 days of hospital stay by managing the cardiac, muscarinic, and nervous system events as detailed in this case report.

Bioremediation of organic compounds and heavy metals has been recognized to be a successful and effective technique in rhizoremediation of soil toxicity using the beneficial microbes which produce different metabolites and enzymes to degrade the toxic compounds/ pesticides available in the soil. In the present study, actinobacterial isolates were explored and identified for bioremediation of soil toxicity available in the soil. The actinobacterial isolates were utilized for the promising PGPR traits and ability to degrade the monocrotophos pesticide residues available in the soil. The "opd" gene of interest responsible for monocrotophos pesticide degradation trait was isolated and cloned in vector DNA to produce recombinant DNA. The recombinant DNA was transformed in E. coli cells to produce multiple copies in E. coli cells resulting in recombinant (transformed) and non-recombinant (non-transformed) colonies. The transformed E. coli cells were inoculated in nutrient broth having pesticide concentration. The transformed cells degraded the pesticide, and the HPLC method determined the derivatives produced. The formulations based on actinobacterial isolates were tested, and field applications were done to determine the reduced soil toxicity, if any, observed.

“…Being readily soluble in water, it is grouped under class 1: highly toxic compounds. Microbes such as Bacillus, Pseudomonas, Aspergillus, Anabaena, and Nostoc at 25-37 0 C and pH 5.5-8.5 can utilize monocrotophos as a nutrient source and can tolerate up to 500-1200 mg L -1 of monocrotophos (Kaur et al, 2019). Monocrotophos and deltamethrin were prepared in different concentration with distilled water, viz., 0.5%, 1%, 1.5%, 2%, 2.5%, 5%, 7.5% and 10%.…”

Seed treatment with pesticides is one of the components of IPM. Pesticides, the chemical ingredients are generally used to assassinate biological entities that cause damage to cultivated crops. To maintain the quantity and quality of the plant produce, a large number of chemicals in the form of pesticides and/or fungicides are sprayed on them. Although these compounds affect the growth of seedlings and also negatively influence the growth of symbiotic bacteria and their interaction with crop plants resulting in a reduction in nitrogen fixation by plants and ultimately yield. A study on the consequences of chemical pesticides on seed germination and seedling growth of Cicer arietinum was carried out at Chhatrapati Shahu Ji Maharaj University, Kanpur, Uttar Pradesh, India in 2016. The present study was done to assess the effect of pesticides on root length, shoot length, leaf area, fresh weight, and dry weight of seedlings. The experiment was conducted by using different concentrations viz., 0% (control), 0.5%, 1%, 1.5%, 2%, 2.5%, 5%, 7.5%, and 10% of organophosphorus monocrotophos and pyrethroid pesticide deltamethrin. Observations were done on the 7th, 14th, and 21st days of radicle emergence. The study showed that both types of pesticides such as pyrethroid deltamethrin and organophosphorus monocrotophos were found to be toxic to plants in high concentrations and can be preferred in low concentrations only like 0.5%, which is less harmful to crop plants.
