What makes a molecule a pre‐ or a post‐herbicide – how valuable are physicochemical parameters for their design?

open access: yesPest Management Science, Volume 77, Issue 11, Page 4863-4873, November 2021., 2021
A high number of parameters influence the fate of herbicides. General characteristics of pre‐ or post‐emergence herbicides can therefore not be defined yet. Abstract Pre‐emergence herbicides are taken up by seeds before germination and by roots, hypocotyls, cotyledons, coleoptiles or leaves before emergence, whereas post‐emergence herbicides are taken ...

The Effects of Structural Alterations in the Polyamine and Amino Acid Moieties of Philanthotoxins on Nicotinic Acetylcholine Receptor Inhibition in the Locust, Schistocerca gregaria [PDF]

open access: yes, 2021
Alterations in the polyamine and amino acid (tyrosine) moieties of philanthotoxin‐343 (PhTX‐343) were investigated for their effects on the antagonism of nicotinic acetylcholine receptors (nAChRs) isolated from the locust (Schistocerca gregaria) mushroom

Modes of action, resistance and toxicity of insecticides targeting nicotinic acetylcholine receptors [PDF]

open access: yes, 2017
Nicotinic acetylcholine receptors (nAChRs) are members of the cys-loop superfamily of ligand-gated ion channels (cys-loop LGICs) and mediate fast cholinergic synaptic transmission in the nervous system of insects.
