Weed Management for Parasitic Weeds

2014
Parasitic weeds, representing more than 4,000 species of more than 20 higher plant families, are one of the most destructive and intractable pests to agricultural production in both developed and developing countries. Parasitic weeds cause heavy damage to numerous crops by reducing both crop yield and quality.

Weed diversity and weed management

Weed Science, 1997
The story of agriculture is the story of weed interference. After millennia of weed control we still have weeds. This situation has led many growers to observe that “the weeds always win.” One of the most important reasons weeds are so successful is their biodiversity. Biodiversity is an inevitable consequence of the struggle an individual weed species

Weed Competition

2017
Weeds compete with crop plants in several different ways. First there can be interference competition where there is physical exclusion from some aspect of the shared habitat. Second there is exploitation competition, which is indirect, and takes the form of competition for a wide variety of resources such as light, water and nutrients.

Weeding with transgenes

Trends in Biotechnology, 2003
Transgenes promise to reduce insecticide and fungicide use but relatively little has been done to significantly reduce herbicide use through genetic engineering. Recently, three strategies for transgene utilization have been developed that have the potential to change this.
