Pesticides are like medicine for plants. Just like how you take medicine when you are sick, plants sometimes need medicine too. But instead of taking pills, plants get sprayed with pesticides. These sprays help keep bugs and other pests from hurting the plants. It's kind of like putting on bug spray before going outside to keep mosquitos from biting you. Pesticides come in different types and strengths depending on the size of the plant and the type of pests that need to be kept away. It's important to be careful with pesticides though because too much can be harmful to the environment and the animals that live in it.
