Efficacy and cost of four plant-derived, natural herbicides for certified organic agriculture. [PDF]

Pest Manag Sci
After three seasons of repeated applications, active ingredients capric and caprylic acid and d‐limonene reduced early season perennial weed cover compared with hand weeding and a do‐nothing control. Abstract BACKGROUND Weed management is the greatest production challenge for most certified organic farmers, with few herbicides allowed on organic farms.

High‐diversity seed additions promote herb‐layer recovery during restoration of degraded oak woodland

Ecological Solutions and Evidence, Volume 4, Issue 1, January–March 2023., 2023
In degraded woodlands, a combination of canopy thinning, removal of non‐native woody plants and reintroduction of fire, often help to restore the herbaceous plant community. We tested whether the addition of a native seed mix leads to improved outcomes compared to passive recovery alone.

Plant community dynamics following non‐native shrub removal depend on invasion intensity and forest site characteristics

Ecosphere, Volume 14, Issue 1, January 2023., 2023
Abstract Globally, temperate deciduous forests are threatened by invasion of non‐native (exotic) plant species. In the eastern United States, Rosa multiflora is a dominant shrub invader in forests, which often forms dense thickets that reduce sunlight availability in the understory, where decreased native plant diversity and abundance are observed ...

Pest categorisation of Nipaecoccus viridis

EFSA Journal, Volume 21, Issue 1, January 2023., 2023
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Nipaecoccus viridis (Hemiptera: Sternorrhyncha: Pseudococcidae), the spherical scale, for the EU. It is of Asian origin and occurs widely in southern Asia, Africa and tropical Australia. It has been introduced to a few countries in the Americas.

AngleCam: Predicting the temporal variation of leaf angle distributions from image series with deep learning

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2531-2545, November 2022., 2022
Abstract Vertical leaf angles and their variation through time are directly related to several ecophysiological processes and properties. However, there is no efficient method for tracking leaf angles of plant canopies under field conditions. Here, we present AngleCam, a deep learning‐based approach to predict leaf angle distributions from horizontal ...

A revised delimitation of the species‐rich genus Pilea (Urticaceae) supports the resurrection of Achudemia and a new infrageneric classification

TAXON, Volume 71, Issue 4, Page 796-813, August 2022., 2022
Abstract Ensuring that genera are monophyletic should result in a stable classification that better reflects evolutionary history, and which can serve as a framework for answering broader scientific questions. It is also important that species can be assigned to genera easily and unambiguously so as to remove barriers to identification and species ...
