Despite numerous cases of herbicide resistance in E. colona worldwide, in Colombia the reports are scarce and most of them dating from over two decades ago. Seedlings of all species emerged be-tween October and March when mean soil temperatures were 21–23°C. In the susceptibility trials, histograms of efficacy of control ranges were created to classify the Echinochloa populations according to their susceptibility to cyhalofop-butyl. Soon et al. This caused selection for weed seeds or plants that were morphologically similar to the crops (Gould 1991). We hope to design a simple and portable glyphosate bioassay system based on the knowledge of synthetic biology.

The full text of this article hosted at iucr.org is unavailable due to technical difficulties. Three sprays of SWE @ 15 L ha-1 showed maximum reduction (65%) over control than other treatments. Glyphosate, the most commonly used herbicide in the world, controls a wide range of plant species, mainly because plants have little capacity to metabolize (detoxify) glyphosate. The most commonly cited species are Oryza sativa, O. glaberrima, O. longistaminata, O. barthii and Echinochloa colona. ABSTRACT. The efficacy of control of Echinochloa populations was always evaluated 30 days after herbicide treatment application (DAT), using conventional scale of visual control, with values from 0 to 100%. It also grows along waterways, on the margins of lakes and ponds, in swamps and wetlands, and in other damp habitats. (Pelbagai perumah untuk Exserohilum monoceras 1125, agen kawalan biologi yang berpotensi untuk kawalan Echinochloa spp.) The two events had the following objectives: • Discussion of the status of the problem in affected countries. Identification and mechanism of Echinochloa crus-galli (L.) resistance to fenoxaprop-p-ethyl via physiological and anatomical differences between susceptible and resistant were investigated. [6] [7] These methods are time-consuming, laborious and complicated. As a result of the intensive use of glyphosate in summer fallows, glyphosate resist- ant populations of E. colona have evolved, with the number of resistant populations identified rapidly growing. It falls into the category of barnyard grasses, which means that it is a member of a broader genus of grasses including millet and other edible rices. Foliar spray.
