C. Pesticides mentioned in the text[edit | edit source]

The word pesticides refers to chemicals used to combat insects, arachnids, nematodes, diseases and weeds. The following table lists the International Organization for Standardization common names of pesticides mentioned in the text, and other common names, along with their more commonly known trade names and notes on their use. The use of italics for a common name denotes that it is no longer used, or in the case of a trade name, that it is no longer manufactured.

All pesticides are hazardous and should be used strictly as recommended by the manufacturer and the local agricultural advisory service. Many countries place restrictions on the use of certain pesticides, including several listed here: some may not be permitted at all, others only if stated conditions are adhered to. Therefore mention of a particular pesticide in this digest does not necessarily imply endorsement by TDRI. There are also internationally approved recommendations and often legal limits on the level of residual pesticide permitted on fresh foods for consumption (whether home produced or imported). The legal limits vary between crops and countries and the regulations are changed from time to time. It will therefore be necessary to check the permitted pesticides and the recommended levels of application with the local agricultural advisory service, and to check the permitted residue levels with the appropriate consumer authority (particularly where there may be exports to countries with possibly different regulations).

Reference to trade names implies no endorsement of the efficacy of these products nor any criticism of competing products not mentioned.
