Pesticide and herbicide contamination refers to the presence and persistence of synthetic or natural plant protection chemicals and their transformation products in environmental compartments such as soil, surface water, groundwater, sediments, air, and biota. Research on this topic examines sources (agricultural runoff, spray drift, leaching, improper disposal), transport and fate processes (sorption–desorption, volatilization, photolysis, hydrolysis, biodegradation), and bioaccumulation and biomagnification in food webs. It also encompasses mixture toxicity, sublethal and chronic effects on non-target organisms, development of resistance, and the use of monitoring, risk assessment frameworks, and remediation or mitigation strategies to manage and reduce ecological and human health risks.
Millions of tons of pesticides are used each year to protect crops, but traditional formulations release too quickly, degrade easily, and leach away, leading to low efficiency and environmental risks.

Water droplets can slide down or bounce off a leaf's surface because it has a waxy hydrophobic (water-repellent) coating. However, this poses a challenge to farmers when pesticides are sprayed, as the droplets can bounce ...

Root-knot nematodes (RKNs) are worm-like parasites of the genus Meloidogyne that are found in many parts of the world. They attack the roots of plants, causing them to wilt and eventually die. It is estimated that crops worth ...
