4Weed Dataset: Annotated Imagery Weeds Dataset [PDF]
arXiv, 2022 Weeds are a major threat to crops and are responsible for reducing crop yield worldwide. To mitigate their negative effect, it is advantageous to accurately identify them early in the season to prevent their spread throughout the field. Traditionally, farmers rely on manually scouting fields and applying herbicides for different weeds.

Herbicide Phytotoxicity and Resistance to Herbicides in Legume Plants [PDF]
, 2012 Active substances in herbicides, just like in other pesticides, are chemical compounds synthesized in order to kill organisms which are harmful for cultivated plants. Therefore, they are toxins introduced on purpose by man into the environment. From the perspective of environmental protection, it is very significant that herbicides are most often ...

Deep Learning with unsupervised data labeling for weeds detection on UAV images [PDF]
arXiv, 2018 In modern agriculture, usually weeds control consists in spraying herbicides all over the agricultural field. This practice involves significant waste and cost of herbicide for farmers and environmental pollution. One way to reduce the cost and environmental impact is to allocate the right doses of herbicide at the right place and at the right time ...
