What does a nematicide control?

A nematicide is a type of pesticide specifically designed to control nematodes, which are microscopic, worm-like organisms that can be pests in agricultural settings and gardens. These pests may cause significant damage to plant roots, leading to reduced plant health and yield. By targeting nematodes, nematicides help prevent or mitigate the damage they can cause, ensuring healthier crops and a more productive growing environment.

The other options represent different categories of pests that are not impacted by nematicides. Flies, ants, spiders, ticks, beetles, and roaches require different forms of pest control products tailored to their biology and behavior. Understanding the target pests for each type of pesticide helps in selecting the appropriate product for effective pest management.
