Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating

According to the disturbance gradient, the species richness of herbaceous vegetation increased from fenced (less disturbed) to fallow (most disturbed). The pastoral value and biomass production of grazing land were higher in protected areas (fenced land) than in unprotected areas (community forests and fallow land), suggesting that conservation ...

Weed population dynamics in rice crops resulting from post-emergent herbicide applications
Studies on weed population dynamics are based on observing and recording changes in weed communities in response to effects of disturbances in crop management. The present study aimed to evaluate weed population dynamics in rice crops in Tolima, Colombia,

ABSTRACT Anthropogenic pressures are increasingly constraining the health of riparian ecosystems by exposing their remnant vegetation to edge effects. Despite being at the land–water interface, conservation efforts have often overlooked how water pollution may indirectly exacerbate the broader impacts of anthropogenic pressures on riparian vegetation ...
