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

Antimicrobial Activity of Catechol and Pyrogallol as Allelochemicals

Zeitschrift für Naturforschung C, 2006
Abstract Catechol and pyrogallol are allelochemicals which belong to phenolic compounds synthesized in plants. Their antimicrobial activities were investigated on three bacteria (Pseudomonas putida, Pseudomonas pyocyanea, Corynebacterium xerosis) and two fungi (Fusarium oxysporum, Penicillium italicum) phytopathogenic species as test ...

The role of arbuscular mycorrhizal fungi in the competition between invasive and native plants depends on the soil nitrogen form

Functional Ecology, Volume 40, Issue 8, Page 2642-2656, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant invasion and nitrogen (N) deposition are escalating global change threats. Arbuscular mycorrhizal fungi (AMF) are increasingly recognized as critical mediators of plant invasion success, largely through their role in enhancing host nutrient acquisition.

The negative effects of an allelopathic invader on native plant photosynthesis are amplified after tree canopy closure

Functional Ecology, Volume 40, Issue 8, Page 2685-2700, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many invasive plants produce antimicrobial allelopathic compounds that disrupt plant–fungal symbioses of native species in the communities they invade, influencing nutrient and water provisioning that support photosynthesis.

Direct and indirect effects of elevated CO2, warming and drought on plant–consumer interactions of Plantago lanceolata

Journal of Ecology, Volume 114, Issue 8, August 2026.
Experimental treatments of warming, elevated CO2, drought and their interactions had direct and indirect (plant‐trait‐mediated) effects on field Plantago lanceolata consumption and feeding preferences of the locust Locusta migratoria. The effects largely differed between consumption types, despite being studied on the same species in the same system ...

Allelochemicals Released from Rice Straw Inhibit Wheat Seed Germination and Seedling Growth

Agronomy
Recently, returning rice straw to soil has become a common problem in wheat production because it causes decreased wheat seedling emergence. Allelopathy is an important factor affecting seed germination.

Allelopathic effects of Cynara cardunculus L. leaf aqueous extracts on seed germination of some Mediterranean weed species

Italian Journal of Agronomy, 2018
It is known that the presence of weeds causes serious losses to the agricultural production, both in quantitative and qualitative terms. The major problem in modern agriculture is the environmental impact of synthetic herbicides and the increase in ...

Inductive Effect of Exogenous Abscisic Acid on the Weed-Suppressive Activity of Allelopathic and Non-Allelopathic Rice Accessions at the Root Level

Agronomy
Rice allelopathy is a natural method of weed control that is regarded as an eco-friendly practice in agroecology. The root growth of allelopathic rice at the seedling stage plays an important role in its weed control.

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.
