An Introduction to Pesticides


Pesticides are chemicals that are used to kill or control pests in agriculture, forestry and home gardens. Pests can be insects, weeds, fungi or rodents.

Pesticides are chemicals that control insects, weeds, fungi and rodents.

Pesticides are chemicals that control insects, weeds, fungi and rodents. They’re used to protect crops from pests that damage them or reduce their yield.

Pesticides can be natural or synthetic in nature. Natural pesticides include insecticides derived from plants (e.g., rotenone) and organic materials such as oils or soaps (e.g., pyrethrum). Synthetic pesticides are made in a laboratory by altering the structure of naturally occurring compounds to make them safer for human use.

The EPA must register all pesticides before they can be sold. Before registering a pesticide, the EPA evaluates its potential risks to people’s health and the environment on an ongoing basis using data collected by manufacturers as well as other sources (such as reports submitted by state pesticide regulatory officials). The federal government also monitors levels of pesticide residues on food products after they’ve been applied to crops—this helps ensure that consumers aren’t exposed to unsafe levels through consumption of fruits and vegetables grown with these chemicals applied.[1]

Herbicides, insecticides, fungicides and rodenticides are the broad categories of pesticides, distinct from each other by the pests they eliminate.

The four primary categories of pesticides are herbicides, insecticides, fungicides and rodenticides. Each of these groups targets a different kind of pest. Herbicides are used to kill weeds. Insecticides eliminate insects like mosquitoes or flies that can harm humans or livestock. Fungicides control fungi such as mold and mildew that can cause damage to crops or other plants. Rodenticides are used to get rid of rodents like rats or mice which may carry diseases into your home if they’re not eliminated quickly enough

Pesticides can be natural or synthetic.

Pesticides can be either natural or synthetic.

Natural pesticides are derived from plants and animals, whereas synthetic pesticides are manufactured. They are more effective than natural ones, which makes them preferable for use in agriculture. This article will discuss the differences between these two categories of pesticides and how they are applied differently to crops.

All pesticides have chemicals that are poisonous to people.

You may have heard of pesticides as a part of your morning routine. The word “pesticides” is used to describe chemicals that are used to kill insects, weeds, and other pests on plants. Pesticides contain toxic chemicals that can be harmful if they get into your body. For example, some fabrics treated with pesticides may cause skin irritation or eye irritation if they come into contact with those areas when you wear them. If you touch the surface where a pesticide was sprayed on (either in liquid or solid form), then it could also make you sick by causing skin irritation and/or eye irritation due to the pesticide coming into contact with those areas of your body.

All pesticides must be registered with the Environmental Protection Agency and the label contains directions for how to use it safely.

The Environmental Protection Agency (EPA) regulates pesticides and requires them to be registered. The label contains specific information about how to use it safely. It also includes details about the active ingredients in the pesticide, how to store it, and any precautions that should be taken when applying or storing a particular pesticide.

Different types of pesticide formulations pose different levels of hazard.

Pesticides are available in a variety of formulations and application methods. The type of formulation and the method of application determine how toxic the pesticide actually is to you and your family.

Formulations can be liquids, dusts, granules or pellets. When pesticides are sprayed on plants they can be applied by hand or machine (aerial sprays). In addition to being applied directly to plants by spraying them with liquid pesticides, they are also used as soil drenches which target insects that live underground feeding on plant roots and root systems. Granular formulations are also used as barrier treatments around plants where they prevent pests from accessing crops while leaf surface sprays repel insects from landing on delicate leaves and fruit surfaces where they would otherwise feed or lay eggs.

Applying pesticides to your crop incorrectly is illegal, ineffective and dangerous.

Applying pesticides to your crop incorrectly is illegal, ineffective and dangerous. Here are a few tips to keep in mind when applying pesticides to your crops:

  • Follow the instructions on the label of the pesticide you’re using. Do not apply more than directed and do not reapply within a specified time period.
  • Apply at the correct time of year (typically between planting and harvest) according to each type of crop being grown, as well as its stage of growth or development (for example, don’t spray young plants).
  • Wear protective equipment such as coveralls and gloves when handling pesticides, especially when mixing them for application.

Use pesticides with care, according to instructions on the label.

Pesticides are labeled with information about how to use them safely. Follow the directions on the label, or you could harm yourself and others.

Use pesticides only when you need them, and only as directed on the label. Use too much pesticide, or use it incorrectly, and it could cause health problems for humans and animals in your neighborhood.

Always follow all of the directions for using a pesticide exactly as they are written on its label!


Pesticides are an important part of growing food and protecting it from pests. It’s important to remember that they are chemicals, so they can be dangerous if you don’t follow the directions on the label.
