Grass 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...

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...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Current Status of Aquatic Weeds and Their Management in India

Aquatic weeds pose several problems in India. The canals of Chambal commanded area in Rajasthan and Madhya Pradesh and Bhakra-Nagal in Himachal Pradesh and Punjab have been greatly slowed by the aquatic weeds. Several irrigation and hydroelectric projects in the country like Tungabhadra project in Karnataka, Nagarjuna Sagar project in Andhra Pradesh and Kakki and Idikki reservoirs in Kerala are...
