Common names of pesticides include some syllables that are familiar to chemists, but members of the general public often have no idea how to pronounce them. Only a few pesticide names find their way into general-purpose printed or online dictionaries that indicate pronunciation.
The pronunciation of common names obviously varies widely in the many countries in which they are used, and so it is not feasible to include pronunciations in ISO 1750 Pesticides and other agrochemicals – Common names.
At one time, the British Standards Institution (BSI) maintained BS 1831 Common names for pesticides in parallel with ISO 1750, and in the 1980’s started work on a revision that was to include an indication of the British pronunciation of each name. The members of a BSI sub-committee devised a British pronunciation for each common name when it was approved.
Between November 2007 and January 2008, these unpublished BSI pronunciations were added to the data sheets. Using these pronunciations as a guide, British pronunciations have now been added to almost all of the other data sheets.
The specification of the pronunciation system was published in BS 1831 : Part 1 : 1985 Appendix C, on which the following is based.
Stressed syllables are marked with HTML <em> tags, which in most Web browsers produce italic type.
Most consonants are given their usual pronunciations, subject to the following:
|g||always hard, as in good, not as in gem|
|j||always as in juniper|
|th||always as in thick, not as in then|
To ensure clarity, the pronunciation of certain other consonants is defined as follows:
|ch||soft ch as in church|
|f||f as in fox|
|ph as in photo|
|k||hard c as in cup|
|hard ch as in chemist|
|kw||qu as in queen|
|ks||x as in ox|
|ng||ng as in ring|
|s||soft c as in cent|
|s as in sound|
|sh||sh as in ship|
Vowel sounds are represented and pronounced as follows:
The following examples show the pronunciation of certain syllables and words:
Some old common names consist of numerals followed by initials, or of initials only, e.g. 2,4-DEP and TEPP. In such cases, each numeral and initial should be pronounced separately, i.e. too for dē ē pē (not twenty-four dep) and tē ē pē pē (not tep).
The International Phonetic Alphabet (IPA) is designed for representing pronunciation, but with versions of Microsoft Windows before Vista the necessary characters are not included in the core fonts and Internet Explorer 7 displays them poorly. The accented characters used in the Compendium are present in Windows XP and Mac OS X 10.4 and later versions, and so most people will be able to see them.
IPA equivalents may be added when most people are able to see them properly in the following table.
Windows Vista and Windows 7 with Internet Explorer 7, Firefox 2 or Opera 9 (or later versions) can display the IPA characters properly.
