The herbicides used were haloxyfop, haloxyfop-methyl, haloxyfop-ethyl, fluazifop-butyl, quizalofop-methyl, and diclofop-methyl each was " C-phenyl labeled. The base formulation was 50% acetone in water with 0.1% (v/v) Ortho X-77 (-COC) for comparison, the base formulation was also formulated with 0.3% (v/v) Agri-dex crop oil concentrate (+COC), which contained 17% nonionic surfactant in a crop oil base. 

Their results demonstrated the importance of structure (and adjuvant) in controlling the penetration mechanism. Cuticle penetration by haloxyfop, haloxyfop-methyl, haloxyfop-ethyl, and fluazifop-butyl without COC followed BP kinetics, being impeded by an initial fast penetration stage. With the exception of haloxyfop, the addition of COC to the formulation simplified the penetration kinetics to SP. The BP behavior in the absence of COC may be due to the relatively rapid penetration of Ortho X-77, leaving the polar pyridinyloxy ester on the leaf surface. These polar esters may require the assistance of the surfactant and/or COC to facilitate cuticle penetration. In contrast, the behavior of quizalofop-methyl and diclofop-methyl was SP in the presence or absence of COC.
