Many farmers choose to use chemicals to keep weeds and pests from destroying their crops and to add more nutrients to the soil. 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.
Herbicides are the most common type of pesticide used, accounting for almost 90 percent of the pesticides used by the agriculture sector.
The term agrochemical or agrichemical is used as a generic term for the chemical products or pesticides used in agriculture. These include herbicides, fungicides and insecticides but also synthetic fertilizers, hormones and soil conditioning agents.
The modern agricultural system that produces our food is absolutely dependent on phosphorus. It is essential. The history of development of phosphorus fertilizer, the sources of phosphorus, and the key role of phosphorus fertilizers are discussed.
The main classes of crop protection chemicals are herbicides, insecticides and fungicides.
Sulfuric acid is the most commonly-produced industrial chemical in the world. Its primary industrial use is to make phosphoric acid which is a main ingredient in most chemical fertilizers.
Synthetic fertilizersModern chemical fertilizers include one or more of the three elements that are most important in plant nutrition: nitrogen, phosphorus, and potassium. Of secondary importance are the elements sulfur, magnesium, and calcium.
Includes insecticides, herbicides and fungicides. The health hazard to humans and animals is mild with herbicides and fungicides, while greater with insecticides.
Agrochemicals include fertilizers, liming and acidifying agents (which are designed to change the pH), soil conditioners, pesticides, and chemicals used in the raising of livestock such as antibiotics and hormones.
Chemistry deals with compounds, both organic and inorganic, and agriculture deals with the production of organic products using both organic and inorganic inputs Thus Chemistry forms an integral part of agriculture from molecular to organ level.
