Weed species and weed communities

Vegetatio, 1978
One 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 and weed control

1993
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 ...

Progress in Biological Control of Weeds with Plant Pathogens.

Annual Review of Phytopathology, 2020
Plant pathogens have played an important role in weed biological control since the 1970s. So far, 36 fungal pathogens have been authorized for introduction across 18 countries for the classical biological control of weeds.

Transfer learning between crop types for semantic segmentation of crops versus weeds in precision agriculture

J. Field Robotics, 2019
Agricultural robots rely on semantic segmentation for distinguishing between crops and weeds to perform selective treatments and increase yield and crop health while reducing the amount of chemicals used.

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 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.

Crop and Weeds Classification for Precision Agriculture Using Context-Independent Pixel-Wise Segmentation

International Conference on Robotic Computing, 2019
Precision agriculture is gaining increasing attention because of the possible reduction of agricultural inputs (e.g., fertilizers and pesticides) that can be obtained by using hightech equipment, including robots.
