Weed species and weed communities
Vegetatio, 1978One of the most satisfying experiences of phytosociological work is the moment when out of the mass of amorphous data begins to crystallize a lattice of general principles and an understanding of vegetation and its ecology. But if one works still further and gathers more and more knowledge in one and the same field, one reaches a deeper level. The more

Weeds have been a major problem in sugar beet since the crop was first grown in the late 1700s. At the end of the eighteenth century, Achard (1799) was already stressing the need to control weeds before the crop was sown. He also noted that once sugar beet was clear of competition from early-emerging weeds it would grow vigorously and smother weeds ...

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.

Weed diversity and weed management
Weed Science, 1997The 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 Management for Parasitic Weeds
2014Parasitic 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.

Weeds are ambiguous plants that disrupt farmers’ territorial plans for a good crop, yet weeds are a necessary component of swidden agriculture systems. In Laos and other parts of Southeast Asia, resilient weeds challenge state plans to compel highland swidden farmers to intensify and “modernize” their traditional agricultural systems.
