Agrichemical typically refers to biocides (pesticides including insecticides, herbicides, fungicides and nematicides) alongside synthetic fertilizers. It may also include hormones and other chemical growth agents.
Plant biochemistry encompasses the chemical reactions that occur within plants. In principle, knowledge at a molecular level informs technologies for providing food. Particular focus is on the biochemical differences between plants and other organisms as well as the differences within the plant kingdom, such as dicotyledons vs monocotyledons, gymnosperms vs angiosperms, C2- vs C4-fixer
Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat. Products with more evenly distributed production see more frequent changes in the ranking of the top producers.
Pesticide products very rarely consist of the pure active ingredient. The AI is usually formulated with other materials (adjuvents and co-formulants) and this is the product as sold, but it may be further diluted in use.
[1] [2] Food supply chains include all actors and activities involved in post-harvest handling, storage, aggregation, transport, processing, distribution and marketing of food; [2] [1] and household consumption, which is the downstream outcome of functioning agrifood systems, subject to varying degrees of demand shocks , such as loss of income ...
The scientific approach to food and nutrition arose with attention to agricultural chemistry in the works of J. G. Wallerius, Humphry Davy, and others.For example, Davy published Elements of Agricultural Chemistry, in a Course of Lectures for the Board of Agriculture (1813) in the United Kingdom which would serve as a foundation for the profession worldwide, going into a fifth edition.
The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1] The University of Hertfordshire maintains a database of the chemical and biological properties of these materials, [2] including their brand names and the countries and dates where and when they have been ...
In the US, the Food and Drug Administration (FDA) and USDA also routinely check food for the actual levels of pesticide residues. [ 21 ] A US organic food advocacy group, the Environmental Working Group , is known for creating a list of fruits and vegetables referred to as the Dirty Dozen; it lists produce with the highest number of distinct ...
