Phytotoxicity-directed extraction and fractionation of the aerial parts of Mikania micrantha H.B.K. led to the isolation and identification of three sesquiterpenoids: dihydromikanolide, deoxymikanolide, and 2,3-epoxy-1-hydroxy-4,9-germacradiene-12,8:15,6-diolide. These sesquiterpenoids inhibited both germination and seedling growth of tested species with deoxymikanolide possessing the strongest phytotoxicity. In a bioassay against lettuce (Lectuca sativa L.), deoxymikanolide reduced radicle… 

Identification and comparison of allelopathic effects from leaf and flower volatiles of the invasive plants Mikania micrantha

TLDR
It was concluded that terpenoids released through volatilization have an important role in the allelopathic effect of M. micrantha, and the oxygenated monoterpene α-terpineol played a crucial role in these effects.

Phytotoxic Potential of Onopordum acanthium L. (Asteraceae)

TLDR
The results indicate that these compounds could contribute to the invasion of O. acanthium in ecological systems and agricultural fields.

Phytotoxic Effects and a Phytotoxin from the Invasive Plant Xanthium italicum Moretti

TLDR
The allelopathic effects of different parts of the plant Xanthium italicum Moretti were evaluated by conducting bioassays against two dicot plants and lettuce, leading to the isolation and identification of a phytotoxin—Xanthinosin—a known sesquiterpene lactone.

Allelopathic potential of Chromolaena odorata and Mikania micrantha on Brassica chinensis var. parachinensis

TLDR
The aqueous leaf Extract of Chromolaena odorata and Mikania micrantha significantly inhibited all growth parameters of B. chinensis and the leaf debris of both species at most of the concentrations showed significant stimulatory effects on all growth Parameters.

Allelopathic effects of 'Chromolaena odorata' (L.) King and Robinson and 'Mikania micrantha' H.B.K. on three selected weed species

TLDR
C. odorata and M. micrantha show allelopathic properties when used as cover crop and mulch by controlling the growth of A. conyzoides and C. iria at all seedling growth parameters and the speed of germination index was the most sensitive compared to that of the other indices.

Effects of Mikania micrantha wilt virus infection on photosynthesis and the activities of four enzymes in Mikania micrantha H.B.K.

TLDR
The activity of PPO in infected M.micrantha leaves reached maximal levels at 8 d post-infection,increasing to 77.75% above control levels,however PPO levels were 14.27% below control levels by 32 d.

Main Alkaloids of Peganum harmala L. and Their Different Effects on Dicot and Monocot Crops

TLDR
This study revealed that total alkaloids from seeds of the medicinal plant Peganum harmala L. harmala possessed significant growth inhibitory effect on four treated plants, with dicot plants being more sensitive than the tested monocot plants.

Effects of aqueous extracts and decomposition of Mikania micrantha H.B.K. debris on selected agronomic crops

TLDR
Germination percentage, radicle length and fresh weight of two crops, Chinese cabbage and tomato, decreased progressively when plants were exposed to increasing concentrations of aqueous extract of Mikania, but did not affect those of corn and long bean seedlings.

Allelochemical Potential of Metopium brownei

TLDR
The aqueous leachates, organic extracts, and the mixtures of flavonoids and urushiols were inhibitory to the growth of test plants and phytopathogenic fungi.

Effects of Mikania micrantha H.B.K. on germination and growth of weed species

TLDR
The plant height of the test species decreased with increasing amounts of debris when either leaf or root debris of Mikania was present on the soil surface or incorporated into the soil.

First Isolation of Natural Cyanamide as a Possible Allelochemical from Hairy Vetch Vicia villosa

TLDR
Cyanamide was isolated from the leaves and stems of hairy vetch, guided by plant growth inhibitory activity against lettuce seedlings, demonstrating cyanamide biosynthesis in the seedlings.

Allelopathic Potential of Aquatic Plants Associated with Wild Rice (Zizania palustris): I. Bioassay with Plant and Lake Sediment Samples

TLDR
The allelopathic potential of eight aquatic plants associated with wild rice was investigated using lettuce and wild rice seedling bioassays and did not yield any conclusive evidence that the wild rice-associated aquatic plants have allelopathy effects on wild rice.

Can failure be turned into success for biological control of mile-a-minute weed (Mikania micrantha)?

TLDR
Progress on biological control of Mikania micrantha Kunth and other weeds of developing countries is discussed in light of the availability and continuity of funding, and Comparisons are drawn between the developed world where a long-term commitment with adequate funding is now generally recognised as necessary, and the developing world, where short-term donor funding makes long- term funding difficult or impossible to obtain.
