Natural Pesticides in Crop Protection: Comparative Advantages, Ecological Risks, and Future Directions

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Although synthetic pesticides have long been used to protect crops, their widespread use has led to significant health and environmental problems, including ecological contamination, resistant pest populations, and hazardous residues in food. These restrictions have sparked interest in natural pesticides (NPs), particularly the secondary metabolites of

Synergistic role of melatonin and ascorbic acid in enhancing fenugreek growth, photosynthesis, antioxidant defense, and diosgenin biosynthesis under UV irradiation

open access: yesPlant Physiology and Biochemistry
UV radiation, particularly UVB, has a large photobiological influence on plants by altering both their biological and biochemical activity. While excessive UVC and UVB exposure can lead to reduced growth, unusual metabolic activity, and impaired photosynthesis, moderate levels of UV act as an environmental signal that plays a crucial role in shaping ...
