This 2016 Compendium of Herbicide Adjuvants is the 13th edition of the biennial publication and contains 779 entries from 38 companies. The first edition of the Compendium was assembled in 1992 and contained 76 entries from 22 companies.

What accounts for such growth in the adjuvant products we list? There are a combination of factors. First, foliar herbicide applications continue to be important. Second, growers need to optimize herbicide efficacy to discourage herbicide resistance. Third, there have been great advancements and innovations in herbicide adjuvant chemistry. Fourth, many adjuvants combine multiple adjuvant groups blended into a single product for greater functionality. Finally, growers are better informed about adjuvants and the value they provide.

While the Compendium of Herbicide Adjuvants is published every two years, the associated website is updated more frequently. This Compendium organizes adjuvant products by type (such as nonionic surfactants, crop oil concentrates, etc.). And each listing includes the product name, manufacturer/distributor, principal functioning agents, use rates, and comments.

Most listings do not include percent “active ingredient” since an industry-wide standard has not been established for the composition of these materials. However, the Council of Producers & Distributors of Agrotechnology (CPDA) has developed a voluntary certification program that requires adjuvant products to meet 17 separate benchmarks for adjuvant composition. For more information about CPDA and a list of certified products, see page 63 or the link below.
