A Review on the Impact of Chemicals Used in Crops on Human Health Rajkumar Yadav pesticides; fertilizers; agrochemicals; residues; human exposure; endocrine disruption; neurotoxicity; carcinogenicity; nitrates; cadmium; integrated pest management; food safety; maximum residue limits Modern crop production relies on a wide array of chemicals—including pesticides, synthetic fertilizers, plant growth regulators, and post-harvest treatments—to secure yields and reduce losses. While these inputs contribute to food security, accumulating evidence links both occupational and dietary exposures to a spectrum of human health outcomes. Documented risks range from acute poisonings and irritant effects to chronic neurobehavioral changes, endocrine disruption, reproductive toxicity, carcinogenicity, cardiometabolic disease, and perturbed gut microbiomes. Risk varies with compound class, formulation, dose, timing, and life stage, and is modified by regulatory controls, residues at consumption, and mitigation practices across the farm-to-fork chain. This review synthesizes epidemiological, toxicological, and risk-assessment evidence; highlights vulnerable populations; summarizes regulatory approaches (ADI, ARfD, MRLs); and identifies practical risk-reduction strategies such as integrated pest management (IPM), safer formulations, improved application practices, and consumer-level decontamination. We conclude with research and policy priorities to align agricultural productivity with human health protection.

The findings showed that, depending on the kind of plant part, solvent employed, and microbial strain tested, both leaf and root extracts have significant inhibitory effects on microbial development. Although root extracts also shown strong antibacterial potential, leaf extracts frequently demonstrated stronger activity because of a higher concentration of phytochemicals. These results emphasize the value of medicinal herbs as all-natural substitutes for synthetic antibiotics, particularly in view of the rise in antimicrobial resistance.

Comparative Analysis of Pollution Syndrome In Native Plants Along Urban–Rural Gradients Kritika Mishra Avshesh Kumar Air Pollution, APTI, Bioindicators, Native Plants, Urban–Rural Gradient, Pollution Syndrome One significant environmental problem that has an impact on ecosystem balance and plant health is air pollution. Native plants are useful bioindicators because they display characteristics of the pollution syndrome, such as physiological and morphological alterations. This study uses the Air Pollution Tolerance Index (APTI) and biochemical data to examine native plant responses to pollution along urban–rural gradients. The findings indicate that urban plants are under more stress, and species that are tolerant have adaptive processes. Thus, native plants are useful instruments for pollution reduction and environmental monitoring (Rai, 2016; Tripathi&Gautam, 2007).

Allelopathic Influence of Invasive Plants on Crop Productivity in Jaunpur Manshi Yadav Avshesh Kumar Allelochemical, Invasive Species, Productivity, Secondary Metabolites Through direct competition and biochemical interactions, invasive plant species have a substantial impact on agricultural output. A key factor in the dynamics of plant invasion is allelopathy, which is the production of secondary metabolites that affect the growth of nearby plants. Allelochemicals can prevent seed germination, slow plant growth, and change the characteristics of soil when they are released through root exudation, leaching, or decomposition. The allelopathic impacts of invasive species on crop productivity in the Jaunpur district are examined in this study. The effects on germination, growth characteristics, and yield of rice (Oryza sativa) and wheat (Triticum aestivum) were evaluated by laboratory bioassays and field observations. The results show that under allelopathic effect, germination percentage, root-shoot growth, and biomass significantly fall. Compared to non-invaded areas, the crop yield in invaded fields was much lower. The results emphasize how crucial it is to control invasive species in order to maintain agricultural productivity and suggest ecologically based integrated weed management techniques.

Role of Plants in the Treatment of Industrial Waste Aman Chaurasia Avshesh Kumar Plant, Phytoremediation Industrialization, Environment, Pollutants Large amounts of wastewater containing hazardous elements such heavy metals, dyes, and organic pollutants are produced as a result of industrialization. Conventional treatment techniques are frequently costly and detrimental to the environment. In this regard, phytoremediation, or plant-based remediation, has become a viable, economical, and sustainable method of handling industrial waste. Pollutants from soil and water can be naturally absorbed, accumulated, broken down, or stabilized by plants. Lemna minor, Pistia stratiotes, and Eichhornia crassipes are examples of aquatic macrophytes that have demonstrated notable efficacy in eliminating pollutants from wastewater. The function of plants in the treatment of industrial waste is covered in this paper, along with methods, methodology, experimental study results, and future prospects. Although issues like sluggish processing rates and biomass disposal still exist, the results show that phytoremediation offers a promising substitute for conventional methods. To maximize its effectiveness, more study and extensive implementation tactics are necessary.

Survey of Plant Diseases in a Local Agro-Ecosystem and Their Management Practices Anshika Yadav Renu Singh Fungal, Bacterial, Viral, Integrated Disease Management, Crop Protection, Agro-Ecosystem, Disease Incidence, And Plant Disease Survey One of the main factors influencing agricultural output and food security in regional agro-ecosystems is plant diseases. In order to identify prevalent plant diseases that occur in crop fields and to assess the management strategies used by farmers to reduce disease, a field study was carried out. Major crops like wheat, rice, tomatoes, potatoes, mustard, and pulses were grown in the sample agricultural area where the study was conducted. Field observations, farmer interviews, and disease incidence reporting were used to gather data. Leaf blight, powdery mildew, rust, wilt, damping-off, bacterial leaf spot, and mosaic virus infection were the main illnesses seen. Cereal crops were mostly impacted by fungal infections including rust and blight, although tomato and potato crops exhibited greater disease incidence due to favorable moisture and temperature conditions.While integrated disease management techniques including crop rotation, resistant cultivars, seed treatment, and field cleaning were less often used, farmers frequently used chemical fungicides and pesticides as the main control approach. The findings showed that the research area's agricultural output and quality were considerably lowered by disease incidence. In order to improve crop health, productivity, and environmental safety, the study stresses the necessity of integrated plant disease management and the significance of raising awareness of sustainable disease management practices.

Use of Agricultural Waste (Tea Waste, Sugarcane Bagasse or Coconut Husk) as Biosorbents for Dye Removal Pratigya Yadav Bal Mukund Seth Adsorption kinetics, wastewater treatment, sugarcane bagasse, tea waste, coconut husk, biosorption, agricultural waste, and dye removal Because of their toxicity, durability, and resistance to biodegradation, the growing discharge of industrial effluents containing dyes constitutes a serious hazard to the environment. For total color removal, conventional wastewater treatment methods are frequently expensive and ineffective. Agricultural wastes including coconut husk, sugarcane bagasse, and tea waste have become affordable, sustainable biosorbents for dye removal in recent years. These materials are abundant in functional groups, lignocellulosic components, and porous shapes that aid in adsorption. The adsorption potential of a few agricultural wastes is reviewed in this work, with a focus on the impact of physicochemical factors including pH, contact time, and adsorbent dosage. The findings show that under ideal circumstances, biosorption employing agricultural leftovers can reach dye removal efficiencies greater than 80–95%. The study emphasizes the potential of agro-waste-based biosorbents as scalable, economical, and environmentally friendly substitutes for traditional adsorbents like activated carbon.

Study on the different chemical treatment on the growth of wheat Kusum Yadav Raj Kumar Yadav Chemicals Climate Drought Tolerance Wheat Chemical treatment is one of the encouraging approaches to refine the drought tolerance of wheat due to the possibility to be applied by both seed soaking and seedling foliar application at various growth stages of the plant. The effects of various chemical molecules treatment on wheat physiology and its productivity under drought were evaluated in this paper. As the climate changes continuously, it adversely treats crop production, particularly wheat cultivation. Chemical treatment is identified to stabilize the drought effect on wheat by improving drought-responsive defense hormones and enzyme activity by boosting stress protein expression and antioxidant enzymes for counteracting the formation of reactive oxygen species. The use of multiple chemicals with pre-and post-emergence treatment has refined drought tolerance to uphold the normal physiology of wheat under changing climates.

A Review Study on Toxic Weed Plants in Jaunpur Region, UP Preeti Bharti Avshesh Kumar Crop loss, invasive species, toxic weeds, Jaunpur, Parthenium hysterophorus, allelopathy, and health risks Intense farming methods, rich alluvial soils, and a tropical monsoon environment that promotes the growth of a variety of weed flora are characteristics of the Jaunpur region in eastern Uttar Pradesh. Among these, a number of weed species have harmful characteristics that negatively impact human health, livestock health, and agricultural output. The identification, distribution, toxicity, and ecological effects of the most toxic weeds in the Jaunpur area are the main topics of this review. Argemone mexicana, Datura stramonium, Euphorbia hirta, Parthenium hysterophorus, and Calotropis gigantea are notable species. Through allelopathy, these weeds create toxic secondary metabolites like terpenoids, glycosides, and alkaloids that induce poisoning, allergic reactions, and crop growth suppression.The study emphasizes how human disturbances and a lack of efficient management techniques are causing them to spread more widely. To reduce their negative consequences, integrated weed management techniques—such as biological control, mechanical removal, and awareness campaigns—are crucial.

Nutritional and Medicinal Value of Wild Edible Plants Anjali Tiwari Avshesh Kumar Food security, phytochemicals, medicinal plants, wild edible plants, ethnobotany, nutritional value, and traditional knowledge A vital yet underappreciated part of the world's biodiversity, wild edible plants (WEPs) play a major role in both traditional healing systems and human nutrition. In addition to bioactive substances like phenolics, flavonoids, and alkaloids, these plants are abundant in vital nutrients like vitamins, minerals, proteins, and dietary fiber. WEPs serve as a primary or supplemental food source in rural and indigenous communities, particularly during times of food crisis. Based on field surveys and a review of the literature, the current study investigates the nutritional value and therapeutic significance of edible wild plants. The results show that WEPs are beneficial for illness prevention and health promotion because they have potent antioxidant, antibacterial, and anti-inflammatory qualities.Due to urbanization and the loss of traditional knowledge, the use of these plants is decreasing despite their significance. Therefore, food security and sustainable development depend on WEP conservation and scientific validation.

Cationic Dyes Removal From Textile Effluents Using Plant-Based Bioadsorbents Ayushi Mishra Balmu kund Seth Methylene Blue, Bioadsorption, Plant-Based Bioadsorbents, Cationic Dyes, Textile Effluents, Wastewater Treatment, Agricultural Waste, Adsorption Isotherms, Sustainable Remediation, and Environmental Pollution. Synthetic dyes, especially cationic dyes, are poisonous, persistent, and nonbiodegradable, the discharge of dye-laden wastewater from textile businesses has become a significant environmental concern. Because these colors reduce light penetration and introduce harmful substances into water bodies, they pose substantia dangers to human health and aquatic ecosystems. Despite their effectiveness, conventional treatment techniques are frequently costly and produce secondary contaminants. In this regard, plant-based bioadsorbents have become a viable and affordable color removal option. Because they contain lignocellulosic components and functional groups like hydroxyl and carboxyl, plant-derived materials including banana peels, rice husk, tea trash, and sugarcane bagasse have a substantial adsorption potential. A number of factors, including pH, contact time, adsorbent dosage, and initial dye concentration, affect the adsorption process. High removal efficiencies, frequently over 90%, have been reported in numerous experiments, and adsorption behavior generally follows pseudosecond-order kinetics and Langmuir and Freundlich isotherms. The efficiency of plant-based bioadsorbents in eliminating cationic dyes from textile effluents is demonstrated in this work, which also underlines the benefits of these bioadsorbents, such as their affordability, availability, and environmental friendliness. These materials have a lot of potential for large-scale wastewater treatment applications, despite some drawbacks like performance fluctuation and regeneration ifficulties. To increase their effectiveness and usefulness, future studies should concentrate on modification strategies and industrial use.
