Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

Pest Management Science, Volume 82, Issue 8, Page 7526-7534, August 2026.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Cordycepin Isolated from Cordyceps militaris: Its Newly Discovered Herbicidal Property and Potential Plant-Based Novel Alternative to Glyphosate

Molecules, 2019
There is currently much interest in finding new phytochemicals among plants and fungi as nature-based alternatives to replace problematic herbicides such as glyphosate, which are preferentially used in agricultural production.

Invasive plant species for compost production: Review of environmental and economic insights

Journal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Invasive plant species pose significant ecological and economic challenges, threatening biodiversity and altering soil properties, while conventional control methods are often costly and resource‐intensive. This review examines the potential of composting invasive plant biomass as a viable and sustainable alternative that aligns with circular ...

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

Pest Management Science, Volume 82, Issue 7, Page 6196-6206, July 2026.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

The Effects of Lantana camara L. on Soil Physicochemical Properties in the Eastern Cape Province of South Africa

African Journal of Ecology, Volume 64, Issue 5, July 2026.
ABSTRACT Lantana camara L. is an invasive alien plant species that is recognised globally due to its extensive distribution and negative impacts on species diversity and ecosystem dynamics. Despite its extensive distribution in South Africa, its physicochemical impacts on soils are understudied. This study investigated the impacts of L.

The Early Response to Urea, Nitrate, or Ammonium and Iron Resupply in Tomato Roots Highlights the Induction of FER, bHLHs, UMAMITs, and MATEs

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Depending on the nitrogen (N) form available to roots, plants activate different transcriptional and metabolic pathways; this can consequently translate into differences in the composition and release of root exudates. To address the existing knowledge gap regarding the relationship between the availability of Iron (Fe) and different N forms ...

2-bromo-1-(2-hydroxyphenyl)-3,4-dimethylpentan-1-one: A New Bromo-Compound with Stimulatory Activity Isolated from the Shed Leaves of Teak, (Tectona grandis L.)

Annals of Tropical Research, 2012
A new Bromo isotopic compound has been isolated and purified from the Methanol Fraction of Teak leaves (MFTk). Chromatographic and spectral analyses (TLC, UV, MS, NMR, and IR) indicated the compound to be 2-bromo-1-(2-hydroxyphenyl)-3,4-dimethylpentan-1-

Allelochemicals and their importance [PDF]

Allelochemicals are secondary plant metabolites capable of influencing the growth, development, and metabolism of other plants, microorganisms, or insects in their immediate environment. These substances are a key mechanism in the phenomenon of allelopathy, which refers to chemical interactions between organisms that can be either positive or negative.
