“…Currently, the majority of studies performed on M. micrantha population genetics have been restricted to China (e.g. Wang et al ., ; Geng et al ., ; Yang et al ., ) and a few native populations in México (Bravo‐Monzón et al ., ).…”

“…At this time, additional research is required to characterise genetic differences among invasive populations to determine whether site‐specific weed management may assist in management of genetically diverse local populations (Ellison et al ., ; Yang et al ., ; Bravo‐Monzón et al ., ). In addition, genetic structure analyses in the native and introduced regions could be used to pinpoint the geographical regions of the source populations in the native range.…”

“…In México, Bravo‐Monzón et al . () analysed genetic structure in native populations of M. micrantha using six SSR markers. The Atlantic and Pacific populations, located on the northern and southern sides of the Mexican Sierra Madre mountain range, showed significant genetic differences and were clearly assigned into different clusters using STRUCTURE analysis (Bravo‐Monzón et al ., ).…”

The Atlantic and Pacific populations, located on the northern and southern sides of the Mexican Sierra Madre mountain range, showed significant genetic differences and were clearly assigned into different clusters using STRUCTURE analysis (Bravo‐Monzón et al ., ). Variation in genetic structure may have been created due to bottlenecks, but suggest significance for site‐specific management, associated with differential susceptibility to a leaf‐feeding beetle, Stolas punicea (Boheman 1850; Coleoptera: Chrysomelidae, Cassidinae, Stolaini; Bravo‐Monzón et al ., ).…”

Increasingly, weeds have been taking on global distributions. With the proliferation of invasive weeds has come the challenge of managing these species over broad geographical regions, with diverse habitats and political jurisdictions. Here, we review the management of Mikania micrantha Kunth (Asteraceae; mile-aminute) throughout its invaded range, extending through most of the Pacific islands and southern and south-east Asia. Context matters when determining the best course of action for managing M. micrantha, as it has invaded a large variety of agricultural and natural systems. In Queensland, Australia and Florida, USA, M. micrantha has been targeted in relatively successful eradication campaigns, highlighting the importance of early detection and rapid response methods, while elsewhere in its invaded range, populations are either still increasing or showing limited signs of decline. An inter-regional approach to research and management should incorporate successful management strategies employed throughout the invaded range including, but not limited to, chemical and cultural control practices, manual and mechanical control, classical biological control using the rust fungus Puccinia spegazzinii, plant-plant competition and integrated approaches utilising two or more control methods concurrently. Additional knowledge of M. micrantha genetics is required to determine if management approaches could be fine-tuned for particular populations. Countries bordering the Mekong River formed a network in 2011 to co-ordinate the management of invasive species such as M. micrantha. Expanding such a collaborative approach to other regions could further reduce populations of M. micrantha and limit its spread.

Commelina diffusa Burm. F. diketahui telah resisten terhadap beberapa jenis herbisida sehingga alternatif pengendalian gulma tersebut perlu diketahui. Mikania micrantha merupakan salah satu jenis gulma yang mengandung senyawa alelopati yang dapat menekan pertumbuhan tanaman di sekitarnya sehingga berpotensi digunakan sebagai bioherbisida. Penelitian ini bertujuan mengetahui potensi ekstrak daun M. micrantha sebagai bioherbisida untuk menghambat pertumbuhan gulma C. diffusa. Penelitian dilaksanakan di Kebun Percobaan Cikabayan dan Laboratorium Pascapanen, Institut Pertanian Bogor pada bulan April-Juni 2019. Rancangan percobaan yang digunakan adalah rancangan kelompok lengkap teracak (RKLT) faktor tunggal yaitu konsentrasi ekstrak daun M. micrantha sebesar 0.00, 0.33, 0.67, 1.00, 1.33, 1.67, dan 2.00 g bobot basah mL-1, dengan 4 ulangan. Aplikasi ekstrak daun M. micrantha mengurangi jumlah daun, meningkatkan skor toksisitas, dan meningkatkan persentase kematian gulma C. diffusa. Hasil penelitian menunjukkan bahwa aplikasi ekstrak daun M. micrantha menekan pertumbuhan daun C. diffusa sampai 2 minggu setelah aplikasi (MSA). Ekstrak daun M. micrantha bersifat toksik bagi pertumbuhan C. diffusa pada 1 MSA dan menyebabkan kematian C. diffusa mulai 10-15 hari setelah aplikasi. Konsentrasi ekstrak daun M. micrantha yang menyebabkan toksisitas pada C. diffusa adalah 1.15 g mL-1. Kata kunci: bioherbisida, gulma, konsentrasi ekstrak, resisten, senyawa alelopati
