General description

Diclofop-methyl is an early post-emergence phenoxypropanoic acid herbicide. Its mode of action involves inhibition of acetyl CoA carboxylase (ACCase) activity, which in turn decreases fatty acid synthesis in weeds and inhibits photosynthesis and the activity of meristem.

Application

Diclofop-methyl may be used as a reference standard for the determination of diclofop-methyl in soil samples by gas-liquid chromatography (GLC).

Diclofop-methyl (DM) is a broad-spectrum herbicide but often shows a reduced biological activity against the target grasses due to its poor water solubility and slow translocation within plant tissues. Randomly methylated beta-cyclodextrin (MCD) is an effective inclusion complexation agent and

Lolium rigidum is an obligately cross-pollinated, genetically diverse species and an economically important herbicide resistance-prone weed. Our previous work has demonstrated that recurrent selection of initially susceptible L. rigidum populations with low herbicide rates results in rapid herbicide resistance evolution.

Cyclodextrins (CDs) possess a hydrophilic external surface and a hydrophobic cavity. They are thus highly soluble and, in the meantime, effectively form inclusion complexes with hydrophobic organic compounds to enhance their solubilities. In this study, the complexation between modified beta-CDs

The frequency of phenotypic resistance to herbicides in previously untreated weed populations and the herbicide dose applied to these populations are key determinants of the dynamics of selection for resistance. In total, 31 Lolium rigidum populations were collected from sites
