Quizalofop-methyl

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.

Halogenated aiyloxyphenoxypropionic acids are a new class of herbicides used for the selective removal of grass species. In commercial preparations, they are present as alkyl esters. In negative-ion ESI, haloxifop, fluazifop, and diclofop all show similar behaviour. The deprotonated molecule is the base peak in the spectrum. Weak formate and acetate adducts occur, and a fragment due to the loss of the propionate part [45]. The analysis of fluazifop and its butyl ester, fenoxaprop, quizalofop and haloxyfop and their ethyl esters, and diclofop and its methyl ester was reported. The free acids were analysed in negative-ion mode, and the esters in positive-ion mode. The esters showed sodium and potassium adducts next to the protonated molecules. The adduct formation was suppressed by the addition of 25 mmol/1 formic acid to the mobile phase. The influence of the orifice potential on the appearance of their mass spectra was studied [46-47]...
