Use of herbicides, in particular sulfosulfuron, at more than recommended doses has raised major concerns about the health hazards for animals and humans. In the present study, isolation of sulfosulfuron-degrading Brevibacillus borstelensis and Streptomyces albogriseolus from the field soils in the northwestern region of India was carried out where the use of sulfosulfuron is predominant, and fu...

We conducted greenhouse experiments to compare photosynthetic and growth responses of 2 invasive annual grasses (downy brome = Bromus tectorum L. and medusahead = Taeniatherum caput-medusae (L.) [Nevski]), 6 caespitose grasses, and 7 rhizomatous grasses to the herbicide sulfosulfuron (1-(2-ethylsulfonylimidazo[1,2-a]pyridin-3-ylsulfonyl)-3-(4,6-dimethoxypyrimidin-2-yl)urea). Our objectives were...

wild barley has invaded wheat fields ever since flamprop-isopropyl was outdated in iran. newly developed herbicides such as sulfosulfuron or sulfosulfuron plus metsulfuron-methyl can control it at higher than recommended dosages, but causing significant wheat injury. hence, two dose-response experiments were conducted to evaluate their efficacy when tank-mixed with thirteen different vegetable ...

Lolium perenne L. (perennial ryegrass) commonly contaminates Agrostis stolonifera (creeping bentgrass) on cool-season golf courses. Currently, few herbicide options are available for the selective control of in A. stolonifera. Previous studies have indicated that flazasulfuron could be a potential solution, so trials were conducted at three sites Blacksburg, VA to evaluate rates and sequential ...

this experiment was conducted at research green-house, department of weed research, iranian plant protection institute, to evaluate the efficacy of sulfosulfuron rates in controlling of barely weed species (including hordeum murinum, h. spontaneum, h. distinchom, h. vulgar) in the 2007. first factor was different times of sulfosulfuron application including 2, 4, 6, 8 and 10 leaf stages and the...

BACKGROUND Bromus rigidus is a common weed species that has increased in cropping fields owing to limited control options. During a random field survey in Western Australia, six B. rigidus populations that had survived in-crop weed control programmes were collected. The study aimed to determine the resistance profile of these six populations. RESULTS Based on dose-response studies, all six B....

A new approach was developed for reducing leaching of herbicides and contamination of groundwater. Liposome-clay formulations of the anionic herbicides sulfometuron and sulfosulfuron were designed for slow release by incorporating the herbicide in positively charged vesicles of didodecyldimethylammonium (DDAB), which were adsorbed on the negatively charged clay, montmorillonite. Freeze fracture...

wild barley (hordeum spontaneum) has invaded to wheat and barley fields since flamprop-isopropyl was obsolesced in iran. the herbicides of sulfosulfuron and sulfosulfuron + metsulfuron-methyl are able to control it at higher-than-recommended dosages, causing a crop injury. hence, two dose-response experiments in factorial experiment with a completely randomized design with four replications wer...

abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...
