What is a nematode and how does it affect plants?

A nematode is a microscopic, often worm-like organism that plays a significant role in the health of plants, though often in a detrimental way. In the context of plants, nematodes are primarily noted for their ability to invade and damage root systems. When they infect plant roots, they can cause various issues, such as stunted growth, wilting, and overall decline in plant health due to their feeding habits. These organisms can disrupt water and nutrient uptake, which is crucial for plant vigor and survival.

Additionally, nematode infestations can lead to secondary infections from pathogens, making plants more susceptible to diseases. Their impact can be particularly pronounced in agricultural settings or gardens where healthy root systems are essential for the plants' overall success. Understanding the role of nematodes is vital for pest control management, allowing for more informed decisions in maintaining plant health and productivity.
