Status: PostprintVarious results of researches report that daisy Creeping Daisy (Wedelia trilobata), Goat weed (Ageratum conyzoides), Siam weed (Chromolaena odorata) and Bittervine (Mikania micrantha) have alellopathic potency to innhibit germination, growth and plant yield.. There were few researches on allelopathic potential of Creeping Daisy, Goat weed, Siam weed and Bittervine on mustard. Therefore, an experiment to evaluate the the allelopathic effects of those weeds on growth and yield of mustard at different concentrations is necessary to be conducted. The purpose of the research was to determine the allelopathic effects of Creeping Daisy, Goat weed, Siam weed and Bittervine on the germination of mustard. The Experiment was conducted from November 2008 until January 2009 at Agronomy Laboratory, University of Bengkulu using Randomized Complete Design (RCD). The experiment consisted of four weed species namely Creeping Daisy, Goat weed, Siam weed and Bittervine and five allelopathic concentrations 10, 20,30, 40 and 50 g/L. The results showed that Siam weed suppressed mustard germination more than other weeds. Allelopathic of Siam weed suppressed shoot length and root length of mustard seedling as much as 42.63% and 45.15% respectively. Shoot and root fresh weight and shoot dry weight of mustard seedling were suppressed as much as 28,23%,56,16% and 56,7% respectively The concentration of 50 g/L extracts from Goat weed andSiam weed was the most toxic to the germination of mustard.

Invasive alien weeds are non-native organisms that cause potential harm to the environment, economics and human health. Its ability to outcompete native species for space, water, nutrients, and other essential resources, adaptability to a variety of environmental conditions, absence of natural predators and parasites and prolific seed producing characteristics, once established it is very difficult to control or eliminate. Eradication through utilization is the present concept of management of invasive alien weeds. Eichhornia crassipes (Mart.) Solms, Salvinia molesta D.S. Mitchell, Parthenium hysterophorus L., Mikania micrantha Kunth, Chromolaena odorata (L.), Mimosa invisa Mart. Ex Colla and Lantana camara L. are the major invasive alien weeds of Kerala. The literature about the bio-utilization of these major invasive alien weeds is reviewed in this paper.

Genetic Aberration

Out of the 4 alien invasive species three are of high risk namely Mikania micrantha, Chromolaena odorata and Mimosa diplotricha. Lantana camara is found to be medium risk. The farmers spent a considerable amount of money nearly Rs 4800 per year for one acre land pertaining to mechanical weeding of invasive species. The herbicide is widely used by farmers to control the weeds are capable to cause various health problems including genetic aberration. So an effective and comprehensive weed management strategy have to be developed in the country to combat the threats of IAS in agriculture fields.

Abstract Many tropical invasive species have strong allelopathic effects. Chromolaena odorata is reported to have the best potential to act as bioherbicide against several weeds on crops. This research was conducted in May-September 2019 to evaluate the efficacy of C. odorata extract on soybean plant. This study employed Randomized Block Design (RBD) Factorial with two factors. The first factor was 4 different doses of C. odorata extracts: 0, 8, 16 and 24 tons ha−1. The second factor was 3 different times of application: 0, 7 and 14 days after planting. Variables observed were number of pods per plant, seed weight per plant, weight of 100 seeds and dry seed yield. The findings indicated that the extract did have effect on seed weight per plant, weight of 100 seeds and yield of dry seeds. The application of extract 16-24 tons ha−1 has improved the seed weight per plant, weight of 100 seeds, and yield of dry seeds. There was no interaction between siam weed extract and time of application in all variables observed.

Tumbuhan liar di sempadan sungai dapat berupa tumbuhan asing/introduksi yang memiliki adaptasi yang tinggi untuk bisa tumbuh dan berkembang lebih cepat sehingga dapat mengganggu tumbuhan lokal. Di ekosistem perkotaan, tumbuhan asing/introduksi sering ditemukan tumbuh di sempadan sungai perkotaan sebagai ekosistem yang terganggu oleh aktivitas manusia. Tumbuhan tersebut mempunyai adaptasi dan ketahanan atau resiliensi untuk tumbuh di habitat yang berubah/terganggu/non-alami, baik akibat manusia atau alam.  Pada umumnya, tumbuhan liar di sempadan sungai tersebut kehadirannya tidak dipedulikan. Namun, tumbuhan tersebut dapat bermanfaat bagi ekosistem sungai, diantaranya sebagai input biomasa/energi, fitoremediasi polutan dan filtrasi air sungai.  Penelitian ini bertujuan untuk mengkaji spesies tumbuhan liar yang ada di sempadan Sungai Ciliwung yang terbangun oleh tebing batu, semen/beton dan potensinya dalam mendukung restorasi Sungai Ciliwung di Kota Bogor.  Metode penelitian yang digunakan yaitu metode random sampling menggunakan plot untuk mengeksplorasi spesies dan tutupan (coverage) spesies di empat lokasi sempadan sungai perkotaan yang berbeton/semen dan terbangun oleh permukiman penduduk di Sungai Ciliwung, Kota Bogor.   Hasil penelitian menunjukkan tumbuhan liar yang ditemukan di sempadan terbangun Sungai Ciliwung Kota Bogor sebanyak 28 spesies: spesies introduksi/asing sebanyak 21 spesies dan spesies lokal sebanyak 7 spesies. Tiga spesies yang mempunyai tutupan terbesar berturut-turut yaitu Pogonatherum crinitum, Mikania micrantha, Chromolaena odorata. Spesies ini merupakan tanaman liar yang memiliki kemampuan fitoremediasi polutan di air sehingga dapat berfungsi untuk memperbaiki kualitas air dengan adanya pemulihan ekosistem sungai dengan melakukan rekayasa ekologi.
