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

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.
