 Weeds are plants growing in the wrong place at the wrong time. Grasses and broadleaved weeds grow under and around trees to compete with their root systems for water and nutrients, and in the case of tall vigorously growing weeds around small stature trees for light and space as well. ‘Lower’ plants like lichens, mosses […]

Himalayan Balsam and its control on the River Monnow in Herefordshire and Monmouthshire

| August 1, 2013

Himalayan Balsam Impatiens glandulifera is sometimes cultivated for its flowers but is now widely established in counties such as the British Isles and the United States and in some situations has become an invasive species weed. Aggressive seed dispersal, coupled with high nectar production which attracts pollinators, often allows the Himalayan Balsam to outcompete native […]

Insect pests are a major cause of damage to the world’s commercially important agricultural crops. Food crops are destroyed by over 10,000 species of insects and cause an annual loss of about 13.6% globally (Benedict et al. 2003) and 23.3% in India (Dhaliwal et al. 2010). During a pest attack, plants, being immobile, do not […]

Better prospect for black-grass control

Better prospect for black-grass control

| August 1, 2013

Scientists at the Universities of York and Durham have discovered a gene called AmGSTF1 that plays a key role in controlling multi-herbicide resistance (MHR) in black-grass and rye-grass. Chemicals that inhibit this gene can be used to make weed killers effective against resistant weeds. Black-grass and rye-grass are both widespread and serious weed problems in […]
