What is the primary use of a nematicide?

A nematicide is specifically designed to control nematodes, which are microscopic, often eel-shaped worms that can cause significant damage to plant roots and soil health. These pests can hinder plant growth by feeding on the roots, leading to weakened plants and reduced crop yields. Therefore, the primary purpose of a nematicide is to target and eliminate these harmful nematodes, making it an essential tool in agricultural and horticultural practices aimed at protecting plant health.

The other choices focus on different types of pests or functionalities. For instance, pesticides that kill insects are categorized specifically as insecticides, those that control weeds fall under herbicides, and products that provide nutrients to plants are referred to as fertilizers. Each type of pesticide has a distinct role and is formulated to tackle specific challenges in plant management, which is why the definition of a nematicide clearly identifies it with nematode management.
