Threats on native flora and fauna by invasive plant species represent one of the main conservation and management challenges in rangelands. Methods that are both effective and ecologically safe to suppress invasives are urgently needed but have rarely been used, thus, highlighting the need to...

A field study was conducted to investigate the floristic composition and phytosociology of the Hazar Nao hills, District Malakand, Khyber Pakhtunkhwa. For study purpose the whole area was divided into 5 Zones. In each Zone 25 sites were selected randomly. Data were recorded from May-September,...

Anthriscus caucalis M. Bieb. and Tagetes minuta L. are reported as the newly naturalized plants of Chinese Mainland. Their morphological characters, photographs and specimens are also provided for identification.

Invasive species are a major threat to environment mainly to biodiversity. Tagetes minuta (Asteraceae) is an invasive plant in Yemen and has an aggressive and negative impact. The present work aims at to determining the germination behavior of invasive T. minuta and noninvasive Tagetes erecta under ...

Ultrasound-assisted headspace solid-phase microextraction (UA-HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS) has been used for analysis of volatile compounds in dry Tagetes minuta L. The highest extraction efficiency was achieved with a 100-µm polydimethylsiloxane (PDMS) fiber....

Use of synthetic pesticides in developing countries is not only limited by their being expensive but also the small (uneconomic) fields whose limited production costs cannot offset costs of agricultural implements like agro-chemicals. Subsistence farmers, therefore, have no choice but to use local...

To understand germination timing in an ecological context, the response to environmental events that affect seed dormancy is central, and has to be combined with knowledge of germination responses to different circumstances. In this study, seed dormancy, germination and emergence phenology of six...

Alien and exotic plant invasions are threatening the floral diversity around the globe and affect ecological processes. Weed invasion has been documented in North-West Pakistan. A total of 16 weeds were reported as invasive. These were Xanthium strumarium, Ipomoea eriocarpa, Alternanthera pungens, ...

Melilotus polonicus L. (Papilionaceae), as psammophyte plant on the Caspian coast, is reported as new noteworthy record for the flora of Iran. Apium leptophyllum (Apiaceae), Sisyrinchium exile (Iridaceae) and Tagetes minuta (Asteraceae) are recorded for the first time from Iran/Flora Iranica area....

Tagetes minuta is an aromatic essential plant with wide range of biological activity including medicinal properties. A study was undertaken to explore the potential herbicidal activity of Tagetes minuta leaf powder (at 1, 2, and 4 t ha^-1) towards two invasive weeds - Echinochloa crus-galli and ...
