Response of Poaceous Weeds in Wheat to Post-Emergence Herbicides
Poaceous weeds are prolific and competitive in winter crops, but they are more insidious in wheat due to their similar morphology and growing requirements. Herbicides are effective and efficient tools of weed management, however, they are vulnerable to resistance, and herbicides with different modes of action might check the dominance of a particular weed flora. The current study was undertaken...

متن کاملGrass Seed Production: Weeds, Herbicides and Fertilisers
Four weed species (Bromus mollis, Vulpia sp., Poa annua, Steltaria media) occur in 30% or more of all perennial ryegrass seed samples. Of the listed undesirable species, Avena fatua (wild oat) and Hordeum murinum occurred respectively in 5.3 and 3.5% of ryegrass seedlots. Only 6 herbicides are registered for use in grass seed crops in New Zealand, 2 for wild oat, and 4 for broadleaved weeds. Th...
متن کاملIsolation and characterization of some important fungi from Echinochloa spp. the potential agents to control rice weeds
Barnyard grass (Echinochloa spp.) is the most important weeds in rice fields. Some fungal pathogens can potentially be used as biological agents for the control and management of these weeds. For this reason, two pathogenic fungal species were isolated and characterized from naturally infected Echinochloa species. Morphological characters of isolates were studied in order to identify the taxono...
