What are crop protection chemicals?
The main classes of crop protection chemicals are herbicides, insecticides and fungicides. Selective herbicides, for example, control the growth of weeds which would otherwise grow among a crop, competing with it for water, nutrients and sunlight. Without crop protection chemicals agriculture would be less efficient.
What are three types of chemicals used in agriculture?
There are three different kinds of pesticides; herbicides, insecticides and fungicides. All three of these pesticides are used to kill different kinds of pests that can be found on a farm. Farmers that make the decision not to use any chemicals are called organic farmers.
What is crop protection in agriculture?
Crop protection products, commonly referred to as pesticides are either naturally occurring or man-made (synthetic) chemicals that help farmers by protecting crops from big losses to pests and diseases and raising productivity per hectare.
What chemicals are used in crops?
Agricultural chemicals are defined as chemicals such as pesticides, herbicides, fungicides, insecticides, and fertilizers used in agriculture to control pests and disease or control and promote growth.
What chemicals do farmers use on crops?
Industrial agriculture relies on two types of chemicals: fertilizers and pesticides. The former boost soil fertility, making crops more productive, while the latter protect crops by controlling weeds (herbicides), insect and animal infestation (insecticides and rodenticides) and fungal/mold diseases (fungicides).
How are chemicals applied to crops?
They may use mechanical methods, such as tillage and hoeing by hand, to manage weeds. Some may release beneficial organisms in fields, especially when managing insect pests. They may also apply chemical pesticides, including herbicides, insecticides, and fungicides, usually through spraying the fields.
What are chemicals in agriculture?

The agricultural chemicals now in use include fertilizers, pesticides, growth regulators, animal feed supplements, and raw materials for use in chemical processes.
What are 5 different types of pesticides?
insecticides (to kill insects) fungicides (to kill fungi) herbicides (to kill plants like weeds) rodenticides (for killing rodents, such as mice)
What is a chemical pesticide?
Pesticides are chemical compounds that are used to kill pests, including insects, rodents, fungi and unwanted plants (weeds). Pesticides are used in public health to kill vectors of disease, such as mosquitoes, and in agriculture to kill pests that damage crops.
What are the types of crop protection?
Certain cultural practices can prevent or reduce insect crop damage. These include destruction of crop residues, deep plowing, crop rotation, use of fertilizers, strip-cropping, irrigation, and scheduled planting operations.
Why crop protection is important in agriculture?
Insect, disease and weed pressures are one of the greatest threats to our food supply as they compete with crops for essential nutrients and rob them of their yield and quality. Farmers rely on crop protection products to prevent these pests from damaging their crops and limiting their harvest.
