Mechanical Weed Control

2009
The aim of this chapter is to highlight and focus on novel and promising developments in soil-engaging intra-row hoeing. Conventional weeding tools for intra-row treatments based on selectivity are limited in control efficacy. Four intra-row weeders based on computer-controlled soil-engaging tools are described. They all rely on input information about

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.

The integration of herbicides with mechanical weeding for weed control in winter wheat

The Journal of Agricultural Science, 2002
Two systems for integrated weed control in winter wheat based around the combination of herbicides with cultural control have been investigated and compared with conventional practice in experiments between 1993 and 2001. These systems were (a) an overall spray of a reduced herbicide dose followed by spring tine harrow weeding and (b) the combination ...

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.

Thermal Weed Control: History, Mechanisms, and Impacts

2018
In the recent years, there has been a revival in the development and improvement of thermal weed control to deliver heat for weed management. Thermal weed control techniques are based on foliar contact mechanisms in which temperatures of approximately 100°C are applied for the duration of few seconds, resulting in intracellular water expansion and cell

Evaluation of mechanical weed control in legume crops

Crop Protection, 2018
Abstract Two three-year field experiments with soya bean (Glycine max (L.) Merr.) and faba bean (Vicia faba L., var. minor Beck.) were carried out in central Italy in order to evaluate the effects of different mechanical methods (spring-tine harrowing, hoeing, hoeing-ridging, split-hoeing, finger-weeding) on weed control and crop yield. Split-hoeing +

Possibilities of mechanical post-emergence weed control in sugar beet

Soil and Tillage Research, 1991
Abstract During a period of four years, 1986–1989, a number of field experiments on post-emergence weed control in sugar beet was carried out. The experiments are components of five weed control systems: chemical; integrated; integrated including ridging; mechanical; mechanical with plants in squares.

Chapter 8 - Mechanical Weed Control

2018
(Uploaded by Plazi for the IPBES Invasive Alien Species Assessment) Evolution of herbicide resistance in weeds has increased the importance and scope of mechanical weed control. In many parts of the world, the efficacy of mechanical weed control has been reevaluated. Tillage (used for soil preparation for planting), although among the oldest methods of

Compatibility of Chemical and Mechanical Weed Control Methods

Weed Science, 1968
Herbicides were applied postplant to field grown peanuts (Arachis hypogaea L.) and cotton (Gossypium hirsatum L.) in association with various cultivation devices. Rotary cultivations were compatible with single or multiple chemical treatments applied to soil.

Innovation in mechanical weed control in crop rows

Weed Research, 2008
SummaryWeed control within crop rows is one of the main problems in organic farming. For centuries, different weed removal tools have been used to reduce weeds in the crop rows. Stimulated by the demand from organic farmers, research in several European countries over the last decade has focused on mechanisation using harrowing, torsion finger weeding ...
