Thermal weed control technologies for conservation agriculture—a review

Weed Research, 2020
Research and development activities on non‐chemical weed control methods to date have mainly focused on mechanical and thermal applications. Selectivity in mechanical weed control is obtained using dynamically actuated harrows. Selectivity in thermal weed control is obtained through a certain heat tolerance of the crop. In conservation agriculture (CA),

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

Hyperspectral species mapping for automatic weed control in tomato under thermal environmental stress

Computers and Electronics in Agriculture, 2011
Highlights? Thermal stress affects tomato canopy reflectance in 480-670 and 720-810nm. ? Temperature-dependent classification performances ranging from 62.5% to 91.6%. ? Omission of 480-670nm stabilizes crop/weed discrimination with 86.4% accuracy. ? Site-specific calibration mitigates extreme temperature effects with 90.3% accuracy. ?
