This review summarises the chemical composition, bioactivity, and pest management potential of T. minuta essential oil, highlighting its prospects as an eco-friendly alternative to conventional synthetic pesticides.
Abstract
Synthetic pesticides have been extensively and often indiscriminately used for the management of insect and mite pests. Their prolonged and excessive use has led to insecticide resistance, environmental contamination, and adverse effects on non-target organisms and human health. These concerns have intensified the search for safer and sustainable botanical alternatives. Tagetes minuta (wild marigold) is a promising candidate, as it produces essential oils rich in bioactive compounds such as (Z)-β-ocimene and tagetone, which possess strong insecticidal, acaricidal, and repellent properties. The efficacy of T. minuta essential oil has been demonstrated against a wide range of pests, including stored-grain insects, field crop pests, and livestock ectoparasites. This review summarises the chemical composition, bioactivity, and pest management potential of T. minuta essential oil, highlighting its prospects as an eco-friendly alternative to conventional synthetic pesticides.
The development of natural insecticides is essential to minimize the adverse effects of synthetic plant protection products on the environment, human health, and non-target organisms. Natural bioactive compounds are considered safe, biodegradable, and often more selective, making them promising alternatives for sustain...

Brassica crops, including collard greens, are economically important vegetable crops cultivated worldwide. Among the major pests affecting these crops, the aphids Brevicoryne brassicae (Linnaeus) and Myzus persicae (Sulzer) (Hemiptera: Aphididae) are particularly relevant due to the direct and indirect damage they caus...

The rapid growth in global population and the incessant demand for food warrant greater attention to sustainable agricultural practices. To ensure adequate food security, protection of crops from exposure to biotic agents (e.g., pathogens and insects) is imperative. Over the decades, synthetic pesticides have been used...
