Eco-friendly pesticides, also known as biopesticides or green pesticides, are chemical or biological agents derived from natural sources that are used to control pests, weeds, and diseases in crops without causing significant harm to the environment, humans, or non-target organisms. Unlike conventional synthetic pesticides, which often contain toxic chemicals that can persist in soil and water and accumulate in food chains, eco-friendly pesticides are biodegradable, target-specific, and have minimal residual effects. These pesticides can be broadly classified into three main categories: microbial pesticides, botanical pesticides, and biochemical pesticides. Microbial pesticides utilize microorganisms such as bacteria, fungi, viruses, or protozoa to suppress pest populations. A well-known example is *Bacillus thuringiensis* (Bt), a bacterium that produces toxins lethal to specific insect larvae while remaining harmless to humans, animals, and beneficial insects. Botanical pesticides are derived from plants and contain bioactive compounds that repel, inhibit, or kill pests. Neem oil, extracted from *Azadirachta indica*, is a widely used botanical pesticide with insecticidal, antifungal, and nematicidal properties. Biochemical pesticides include substances such as pheromones or plant growth regulators that interfere with pest reproduction, feeding, or development, thereby reducing their impact on crops without directly killing them. The adoption of eco-friendly pesticides in the agrochemical sector is crucial due to their environmental compatibility and safety profile. Traditional chemical pesticides, although effective in controlling pests, often cause soil degradation, water pollution, and loss of biodiversity. Residual chemicals can contaminate groundwater and food products, leading to long-term health risks in humans and livestock. Eco-friendly pesticides, on the other hand, are designed to break down into harmless components after application, reducing the risk of environmental contamination. Their specificity ensures that beneficial organisms such as pollinators, natural predators, and soil microbes are not adversely affected, thereby supporting sustainable agricultural practices. Additionally, the use of biopesticides can mitigate the development of pest resistance, a major concern associated with the repetitive use of synthetic chemical pesticides. Microbial and botanical pesticides often contain complex mixtures of active compounds, making it difficult for pests to develop resistance rapidly, ensuring long-term effectiveness in crop protection. In the agrochemical sector, eco-friendly pesticides play a significant role in integrated pest management (IPM), an approach that combines biological, cultural, mechanical, and chemical methods to control pests in a sustainable manner. By integrating eco-friendly pesticides into IPM strategies, farmers can reduce reliance on hazardous chemicals,
