BACKGROUND: Previous work has demonstrated that piperonyl butoxide (PBO) not only inhibits microsomal oxidases but also resistance-associated esterases. The ability to inhibit both major metabolic resistance enzymes makes it an ideal synergist to enh

Acetylcholinesterase (AChE) is the target of a major pesticide family, the organophosphates, which were extensively used as control agents of sea lice on farmed salmonids in the early 1990s. From the mid-1990s the organophosphates dichlorvos and azam

Five contemporary strains of the bollworm Helicoverpa armigera Hubner from China, Pakistan and India, all with high resistance to pyrethroids, were compared with a standard susceptible strain that originated from the Cote D’Ivoire in the 1970s (‘

The main mode of herbicidal activity of 2-hydroxy-3-alkyl-1,4-naphthoquinones is shown to be inhibition of photosystem II (PSII). The herbicidal and in vitro activities have been measured and correlated with their (Log)octanol/water partition coeffic

Two pesticidal naphthoquinones from Calceolaria andina (Scrophulariaceae) both contain a key structural feature not previously investigated in this group of compounds. Structure–activity studies have led to the identification of analogues with comm

We have synthesised two photoaffinity-labelling hydrophobic stilbene urea inhibitors of Photosystem 2 (PS2) bearing either an azido group (3-(3-((E)2-(4-azidophenyl)ethenyl)-phenyl)-1,1-dimethylurea, azido-PDU) or a diazirine group (3-(3-((E)2-(4-(3-

Photosystem-2 reaction centres were prepared from pea thylakoid membranes that had been photoaffinity labelled with [14C]-azidoatrazine (2-azido-4-ethylamino-6-isopropylamino-s-triazine), a derivative of the herbicide atrazine which binds to the seco

The toxic effects of six acylurea insecticides on larvae of the tobacco hornworm were investigated at each of four environmental temperatures (20, 25, 30 and 35°C). This spans the range of temperatures which the insects can tolerate. For all the acy

Flufenoxuron is an acylurea insecticide which inhibits chitin synthesis. Its uptake, excretion and metabolism in larvae of Spodoptera littoralis have been measured. Larvae fed on a leaf disc sprayed at an application rate equivalent to 50 g ha−1rap
