Among plant strategies to invade and dominate the plant community, the release of alelochemicals is prominent. These compounds are present in all plant parts, principally, in root exudates, leaves and their degraded parts. They are released in the environment through volatile or soluble emanations, translocated in water. Capim-annoni-2 is an invasive exotic Poaceae of rangeland vegetation with allelopatic potential. To test this effect, plant structures from the mid part of capim-annoni-2 were… 
Phytotoxicity and allelopathic potential of extracts from rhizomes and leaves of Arundo donax, an invasive grass in neotropical savannas
TLDR
The allelopathic potential of this species is confirmed and caution against weed control methods relying on cutting the plant back to soil level for favouring release of allelochemicals is cautioned.
Chemical ecology of Eragrostis plana helps understanding of the species’ invasiveness in an agroecosystem community
TLDR
The extracts showed suppressive, stimulating or neutral effects on the development of the radicle, shoots, and total lucerne and wheat seedlings, with greater phytotoxicity, generally, of ethyl acetate and methyl alcohol extracts.
Interações entre herbicidas e protetores para o controle de capim-annoni em pastagem natural
TLDR
The use of herbicides in association with safeners indicated a potentiality for selective control of E. plana when applied to plants in the early stages of development.
Pattern of allelochemical distribution in leaves and roots of tough lovegrass (Eragrostis plana Nees.)
TLDR
The results demonstrated greater amount of compounds in the leaves of tough lovegrass than previously demonstrated; therefore, this organ should be prioritized in the future with isolation of compounds.
Allelopathy and Allelochemicals of Eragrostis plana (Poaceae) and its Relation with Phenology and Nitrogen Fertilization
TLDR
The management of the nitrogen fertilization and the harvesting age influence the allelopathic activity and the phytochemical composition of tough lovegrass.
Crescimento de plântulas de trevo-branco tratadas com extratos aquosos de folha e raiz de capim-annoni-2
TLDR
The results suggest that allelopathic compounds from leaves and roots of tough lovegrass differ in chemical nature and/or concentration.
Evaluation of allelopathic potential of leaf extract of kielmeyera coriacea on lactuca sativa l
TLDR
Data indicate that K. coriacea presents an allelopathic potential because its leaf extracts interfere with germination and growth without any interference of pH and osmotic potential in the results.
INFLUENCE OF PHENOLOGY AND POST-HARVEST PROCESSING OF VEGETAL MATERIAL ON THE ALLELOPATHY OF ANNONI GRASS ( Eragrostis plana ) EXTRACTS
The phenological stage, post-harvest processing and quantity of material can interfere in the allelopathic activity of extracts. The objective of this study is to test the allelopathic effect of
Influence of Phenology and Post-Harvest Processing of Vegetal Material on the Allelopathy of Annoni Grass (Eragrostis plana) Extracts
TLDR
The sensitivity of the white clover to extracts of Annoni grass suggests a compromise of its establishment in pastures with the presence of the invader.
The first anatomical and histochemical study of tough lovegrass (Eragrostis plana Nees, Poaceae).
TLDR
Anatomical and histochemical traits of tough lovegrass suggest that the plant has adapted to survive under biotic and abiotic stress, which enhances its performance in relation to native plants.

Avaliação do potencial alelopático de genótipos de aveia no início do ciclo
TLDR
Results of this study showed that oat genotypes present allelopathic potential, and the effects caused by the allelochemical scopoletin are similar to those observed by oat Genotypes, suggesting a cause and effect relationship.
Allelopathy: Basic and Applied Aspects
TLDR
A discipline called allelopathy, with case studies in natural and managed ecosystems, and the allelopathic potential of aromatic shrubs in phryganic (East Mediterranean) ecosystems.
Allelopathy and exotic plant invasion
TLDR
It is argued that non-resource mechanisms should be returned to the discussion table as a potential mechanism for explaining the remarkable success of some invasive species.
Allelopathy—An update
TLDR
There has been a rapid advance in knowledge of mechanisms of action of known allelopathic compounds, at increasingly more fundamental levels, and evidence is mounting that inhibition of nitrification increases as succession progresses toward the climax vegetation, at least in many vegetation types.
Substâncias fitotóxicas presentes no capim-annoni-2
TLDR
Concluiu-se that esse capim libera substâncias fitotoxicas ao ambiente e that estas permanecem biologicamente ativas no solo.
