Robel Pole Method Can Estimate Cereal Rye Biomass to Optimize Termination Timing

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Fully realizing the benefits of cover crops and minimizing the yield penalty requires knowing when to terminate them. Cereal rye (Secale cereale L.) is the dominant cover crop used in the Midwest US, and previous work has shown that corn (Zea mays L.) yield penalties began to occur more frequently when cereal rye is at ∼1000 lb dry biomass ac ...

Evaluating Sweetpotato Varieties and Accessions in Hawai‘i

open access: yesHortTechnology
Thirty sweetpotato (Ipomoea batatas var. batatas) genotypes were evaluated for yield, resistances to weevil or nematode pests, and consumer acceptance across three field trials planted at Pepe‘ekeo, Hawai‘i Island between 2017 to 2020.

Early Contributions Leading to Understanding the Significance of Epichloë Endophyte in Temperate Grasses

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
The role and use of Epichloë fungal endophytes in grazed temperate grass pastures and turf grasses are now well understood with regard to balancing pasture persistence while minimising animal health and welfare concerns. However, this understanding has only emerged since the early 1980s. Prior to this, although links between Epichloë endophytes, animal

Impact of crop sequence on cereal yield and soil health in shallow dryland soils

open access: yesAgronomy Journal, Volume 118, Issue 5, September/October 2026.
Abstract Diversifying small‐grain production systems is encouraged in the US northern Great Plains and similar semiarid regions. Our objective was to determine how crop sequence affected small‐grain crop disease, grain yield, and soil biology in shallow dryland soils of central Montana. Barley (Hordeum vulgare L.), canola (Brassica napus L.), field pea

Seasonal Effect on the Chemical Composition of Lippia alba Volatile Chemotypes

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
L. alba, a Brazilian medicinal species, is known for its volatile chemotypes, with fewer studies of its nonvolatile composition. Chemical characterization via GC‐MS and LC‐MS of five individuals, during the rainy and dry season, confirm the variability of the volatile composition but the nonvolatile composition was similar, with a discrete seasonal ...

Population Genomics Approaches Identify a Cryptic, Emerging Generalist Pest Complex

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Molecular gut content analysis and RAD‐seq analysis revealed a peanut pest complex where previously only one species was considered problematic. Both species exhibited a wide, but somewhat distinct, variety of plants among their diets, and peanut‐feeding was rare. Diet generalism combined with a stepwise pattern of dispersal among fields might underlie

Diaprepes Root Weevil, Diaprepes abbreviatus (Linnaeus) (Insecta: Coleoptera: Curculionidae)

open access: yesEDIS, 1998
This document provides an in-depth profile of the Diaprepes root weevil, Diaprepes abbreviatus, a significant pest in Florida. Native to the Caribbean, it was first reported in Florida in 1964 and has since spread, causing extensive damage to citrus and

From Suitability to Invasion Risk: Integrating Correlative and Mechanistic Models for Predicting the Potential Distribution of the Red Palm Weevil

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
The invasive Rhynchophorus ferrugineus (RPW) causes severe economic and ecological damage to palm systems worldwide. This study develops a hybrid modeling framework integrating correlative ecological niche models and a temperature‐driven mechanistic risk index, demonstrating superior predictive accuracy (sensitivity = 0.98) compared to individual ...

Clover root weevil tolerance of clover cultivars

open access: yesJournal of New Zealand Grasslands, 2016
Clover root weevil arrived in New Zealand about 20 years ago causing major loss of productivity as it progressively spread across the whole country. It is now largely controlled by an introduced parasitic wasp biocontrol agent Microctonus aethiopoides (Irish ecotype). However, management of insect pests should not rely on a single mechanism and clovers

Effects of two protease inhibitors on larvae of Argentine stem weevil and clover root weevil

open access: yesNew Zealand Plant Protection, 2002
Protease inhibitors (PIs) cause mortality in a range of insects and transgenic plants expressing PIs have been protected against pest attack The effects of feeding two purified PIs to larvae of Argentine stem weevil (Listronotus bonariensis) and clover root weevil (Sitona lepidus) were investigated in laboratory bioassays The serine PI aprotinin and ...
