Precision Robotic Spot-Spraying: Reducing Herbicide Use and Enhancing Environmental Outcomes in Sugarcane [PDF]
Precise robotic weed control plays an essential role in precision agriculture. It can help significantly reduce the environmental impact of herbicides while reducing weed management costs for farmers. In this paper, we demonstrate that a custom-designed robotic spot spraying tool based on computer vision and deep learning can significantly reduce ...

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.

Quinclorac Resistance in Echinochloa crus-galli from China
Rice Science, 2019 Echinochloa crus-galli is a major weed in rice fields in China, and quinclorac has been long used for its control. Over-reliance of quinclorac has resulted in quinclorac resistance in E. crus-galli. Two resistant (R) E. crus-galli populations from Hunan,

A bibliometric analysis of herbicide resistance in Africa
Scientific African, 2023 Herbicides were introduced in the 1950s, and since then, there has been an increase in herbicide-resistant weeds. This is apparent from the multiple (503) literature reviews on herbicide resistance worldwide.

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 ...

Biological Diversity, EarlyView.Abstract The production of Carica papaya L. in Kenya is seriously affected by the Moroccan watermelon mosaic virus and lack of improved varieties leading to the importation of expensive seeds for the resource‐scarce farmers. To curb these challenges, new papaya hybrid lines were recently selected and bred, but their growth traits and performance ...
