eChemicals are listed alphabetically by common or generic names proposed by organizations such as the Weed Science Society
of America and the Entomological Society of America. Common names followed by an asterisk designate chemicals subjected
to limited toxicity testing, which are summarized in Table 4 (p. 81).
