Okay, so you know how we have to clean and wash our fruits and vegetables before eating them, right? That's because there are small insects and other creatures that might make a home on them and it's better to be safe than sorry. Pesticides are like cleaners for our crops. They are chemicals that the farmers spray on their plants to keep all the little bugs and creepy crawlies away.
But just like with soap, you have to be careful not to use too much pesticide. If you use too much, it can actually hurt the plants or be harmful to animals and people who eat the fruits and veggies. That's why it's really important for farmers to follow the instructions on how much pesticide to use and when to use it.
Some people worry about pesticides because they might not want to eat something that had chemicals sprayed on it. But if the farmers are careful, the only thing left on the fruit or vegetable should be a really small amount of pesticide, which shouldn't hurt us.
So, pesticides are like bug spray for plants to make sure they don't get eaten by creepy crawlies, but we have to be careful not to use too much or it might hurt the plants or us.
