Nematicidal activity of plant extracts against the root-knot nematode, Meloidogyne incognita [PDF]
Nematicidal activity of extracts from plants was assayed against Meloidogyne incognita. In laboratory assays extracts from tobacco (Nicotiana tabacum L), clove (Syzygium aromaticum L), betelvine (Piper betle L), and sweet flag (Acorus calamus L) were ...

Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Conservation status of species used in the UK herbal medicine industry
Given the ongoing biodiversity crisis, sustainable use and management of medicinal plants is critical. We assessed the conservation status, threats and conservation actions of 298 species sold by UK suppliers to medical herbalists. We found that most species used are unevaluated, representing a gap in conservation knowledge, and of those with ...

SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.
