Integrating red-green-blue, thermal, hyperspectral, and multispectral sensors with unmanned aircraft systems and artificial intelligence ensures better results in managing the weed menace. Since India depends largely on agriculture, it is still a long way from implementing more advanced weed management methods. Mapping and surveillance of weeds in croplands by employing remote sensing will lead to varied herbicide application rates, thus reducing its overuse. This study reviews the practical application of remote sensing methods and unmanned aircraft systems in weed mapping UAS; weed mapping; artificial intelligence; remote sensing; sensors 10.17221/74/2024-PPS https://pps.agriculturejournals.cz/artkey/pps-202501-0003.php https://pps.agriculturejournals.cz/artkey/pps-202501-0003.php continuing 61 1 44 55 2025 12122580 periodical academic journal
