Micro-Mechanization to Manage Weed in Sugar Cane [PDF]

Sugar Tech
Reducing herbicide usage is not only expected by society at large, it is also vital to protect our health and the environment. With labour being scarce, weed control using micro-mechanization methods is a useful technique that is well-suited to the sugarcane context in Réunion.

Weed seed production, crop planting pattern, and mechanical weeding in wheat

Weed Science, 2002
Abstract Experiments were carried out to investigate weed seed production in widely spaced spring wheat crops that received aggressive mechanical weed control (hoeing and harrowing) compared with that in narrowly spaced crops receiving less aggressive mechanical control (harrowing only). Three species (wild buckwheat [Polygonum convolvulus], ladysthumb

Mechanical Weed Control in Agriculture

2001
Weeds are plants that are considered undesirable in a crop at a given time.Weeds are harmful for a number of reasons. They reduce crop yields, interfere with the harvest, support pathogens and insect pests and contaminate seeds.

Photosynthetic Mechanisms of Weeds in Taiwan

Australian Journal of Plant Physiology, 1993
One hundred and one species (in 36 families) of weeds on cultivated land in Taiwan were investigated for the occurrence of Kranz leaf anatomy and activities of key enzymes of C4 photosynthesis to determine their photosynthetic mechanisms. Based on the anatomical and biochemical analyses, 75 species were found to possess the C3 and 26 species the C4 ...

Early Physiological Mechanisms of Weed Competition

Weed Science, 2012
Early physiological mechanisms that occur in crop plants in response to neighboring weeds are not well understood. In this experiment, it was hypothesized that, in the absence of direct competition for resources, low red to far red ratio (R:FR) reflected from neighboring weeds will modulate the phenylpropanoid pathway, increase hydrogen peroxide (H2O2),

Evolution of herbicide resistance mechanisms in grass weeds

Plant Science, 2014
Herbicide resistant weeds are becoming increasingly common, threatening global food security. Here, we present BrIFAR: a new model system for the functional study of mechanisms of herbicide resistance in grass weeds. We have developed a large collection of Brachypodium accessions, the BrI collection, representing a wide range of habitats.

Mechanical damage to annual weeds and carrots by in‐row brush weeding

Weed Research, 1999
Field experiments were carried out in order to assess the selectivity of in‐row brush weeding in carrots with a natural flora of annual weeds, represented by Urtica urens L., Stellaria media (L.) Vill., Chenopodium album L., Senecio vulgaris L., Capsella bursa‐pastoris (L.) Med., Chamomilla suaveolens (L.) Pursh Buch. and Matricaria inodora L.

Intra-row mechanical weed control—possibilities and problems

Soil and Tillage Research, 1997
Abstract For five years, graduate students of the Tillage Laboratory of Wageningen Agricultural University studied the effectiveness of intra-row weed control by brushes, tactile hoes and weeder harrows in combination with a drill planting system and paper pots.

Robotic weeding's false dawn? Ten requirements for fully autonomous mechanical weed management

Weed Research, 2016
SummaryWhile machines called weeding robots are now commercially available and many more designs are being actively researched, I contend that current machines are not truly robotic weeders, rather they are essentially self‐guiding vehicles carrying weeding tools. I consider true robotic weeders to be a far more difficult objective.

[Chemical mechanism of exotic weed invasion].

Ying yong sheng tai xue bao = The journal of applied ecology, 2005
The ecological and economic impacts of exotic invasive weeds have been followed with interest. A successful invasion of exotic weeds depends not only on their bio-ecological traits, but also on some specific mechanisms of invasion. The clarification of the invasive mechanism of exotic weeds will be beneficial to predict and manage on them.
