Weed Mapping in Vineyards Using RGB-D Perception [PDF]
The 13th EFITA International Conference, 2021 Weed management is one of the major challenges in viticulture, as long as weeds can cause significant yield losses and severe competition to the cultivations. In this direction, the development of an automated procedure for weed monitoring will provide useful data for understanding their management practices.

Biotechnological Road Map for Innovative Weed Management
Frontiers in Plant Science, 2022 In most agriculture farmlands, weed management is predominantly reliant on integrated weed management (IWM) strategies, such as herbicide application. However, the overuse and misuse of herbicides, coupled with the lack of novel active ingredients, has resulted in the uptrend of herbicide-resistant weeds globally. Moreover, weedy traits that contribute

Mapping and Estimating Weeds in Cotton Using Unmanned Aerial Systems-Borne Imagery
AgriEngineering, 2020 In recent years, Unmanned Aerial Systems (UAS) have emerged as an innovative technology to provide spatio-temporal information about weed species in crop fields. Such information is a critical input for any site-specific weed management program.

Selection of Grids for Weed Mapping [PDF]
Planta Daninha, 2015 This study aimed to assess the degree of similarity presented by thematic maps generated by different sampling grids of weed plants in a commercial agricultural area of 7.95 hectares. Monocotyledons and dicotyledons were counted on the 2012/2013 and 2013/2014 harvests, before soybean planting, in the fallow period after wheat harvest, in both years.

The Art and Science of Weed Mapping
Environmental Monitoring and Assessment, 2007 Land managers need cost-effective and informative tools for non-native plant species management. Many local, state, and federal agencies adopted mapping systems designed to collect comparable data for the early detection and monitoring of non-native species.
