Leptochloa chinensis (L.) Nees, is known as a noxious weed species in upland and lowland crop cultivation, has naturalized many countries an invasive plant species. In this study, the allelopathic characteristic of L. was evaluated to understand its invasiveness. An aqueous methanol extract above-grand parts suppressed growth species; Echinochloa crus-galli Beauv., Vulpia myuros C. Gmel. Lolium...
Biomassa gulma eceng gondok (Eichhornia crassipes) mengandung zat allelopati yang dapat dimanfaatkan sebagai bioherbisida. Penelitian bertujuan untuk mengetahui potensi ekstrak bioherbisida mengendalikan pada padi sawah. dilaksanakan November 2016 hingga Agustus 2017 di Kebun Percobaan Cikabayan dan Laboratorium Ecotoxicology Waste and Bioagents, Departemen Agronomi Hortikultura, IPB. disusun d...
As noted above, the issue of mid-level health workers was addressed in the Pick report of 2001. The decision to establish mid-level medical workers was taken in December 2002 at MinMec (now called the National Health Council) and confirmed in January 2004. Investigations and consultations have taken place since then with a wide range of stakeholders and role players including the health science...
Coumarin is a natural compound well known for its phytotoxic potential. In the search for new herbicidal compounds to manage weeds, three synthetic derivatives bearing the coumarin scaffold (1-3), synthesized by a carbonylative organometallic approach, were in vitro assayed on germination and root growth of two noxious weeds, Amaranthus retroflexus and Echinochloa crus-galli. Moreover, the synt...
Barnyard grass (var. onyzicela) showed no apparent damage in paddy fields where hopperburn occurred by a large number of NL lugens. The causes of barnyard grass resistance to this inscct and thc insect-host interrelations of threc species of planthoppers (N. Iugens, L. striatellus and S. farctfera) between rice plant and barnyard grass were studicd. Nymphs of IV. Iugens could not grow by feedin...
We compared photosynthesis and growth of Zea mays L (corn) and four weed species, Setaria viridis (L) Beauv (green foxtail), Echinochloa crus-galli (L) Beauv (barnyardgrass), Abutilon theophrasti Medic (velvetleaf), and Amaranthus retroflexus L (redroot pigweed), following foliar applications with atrazine, mesotrione, or a combination of atrazine and mesotrione in two greenhouse experiments. P...
Soybean field experiments were performed to investigate the weed-suppressing effects of different tillage systems and cover crop mulches at two locations in southwest Germany during 2014 and 2015. The influence of three different tillage systems on weed control efficacy, soybean plant density, and crop yield was determined. In the no-till system (NT), two different cover crops, (rye and barley)...
Miscanthus is a genus of perennial rhizomatous grasses with C4 photosynthesis which is indigenous in a wide geographic range of Asian climates. The sterile clone, Miscanthus × giganteus (M. × giganteus), is a naturally occurring interspecific hybrid that has been used commercially in Europe for biomass production for over a decade. Although, M. × giganteus has many outstanding performance chara...
