(L.) Correa is an economically and therapeutically valuable tree. It is cultivated as a fruit plant in southeast Asian countries. In this research, we investigated the allelopathy and possible allelochemicals in the leaves of . Aqueous methanol extracts of exhibited significant inhibitory effects against the growth of , , , , , and . Bioassay-directed chromatographic purification of the extracts resulted in identifying five active compounds: umbelliferone (), -ferulic acid (), ()-4-hydroxycinnamic acid methyl ester (), -cinnamic acid (), and methyl ()-3'-hydroxyl-4'-methoxycinnamate (). The hypocotyl and root growth of were considerably suppressed by these compounds. Methyl ()-3'-hydroxyl-4'-methoxycinnamate also suppressed the coleoptile and root growth of . The concentrations of these compounds, causing 50% growth reduction () of , were in the range of 74.19-785.4 μM. The findings suggest that these isolated compounds might function in the allelopathy of .

The identification of sex pheromones in native New Zealand moths has been limited, largely due to their minimal pest impact on agricultural ecosystems. The kōwhai moth, Uresiphita polygonalis maorialis, a native crambid, is known for its herbivory on Sophora spp. and Lupinus arboreus leaves.

Ambrosia trifida is an invasive weed that destroys the local ecological environment, and causes a reduction in population diversity and grassland decline. The evolution of herbicide resistance has also increased the difficulty of managing A. trifida, so interspecific plant competition based on allelopathy has been used as an effective and sustainable ecological alternative.

is an important medicinal herb; but its long-term cultivation often leads to continuous cropping problems. The underlying cause can be attributed to the accumulation of and alterations in root exudates; which interact with soil-borne pathogens; particularly ; triggering disease outbreaks that severely affect its yield and quality. It is therefore crucial to elucidate the mechanisms by which root exudates induce CCS043 outbreaks.

The brown planthopper (BPH) Nilaparvata lugens (Stål) is a major insect pest of Oryza sativa that causes crop yield loss in tropical regions, including Thailand. In this study, the crude ethanolic extract of the leaves and branches of Combretum trifoliatum , its active isolated components, apigenin and camphor, and Finopril were tested for their ability to control the first to fifth instars of N. lugens.

The tea moth pest, is an economically important and highly damaging pest that drastically affects tea plant leaves. The chemical composition of its pheromone glands metabolites before and during calling period has not been reported yet. Therefore, the present study aimed at the metabolomic profiling of female moths' sex pheromones glands before and during calling period using gas chromatography time-of-flight mass spectrometry.
