Can high resolution UAV-derived weed maps replace camera-based targeted spray application?

Frontiers in Agronomy
Efficient weed mapping is critical for enabling site-specific weed management (SSWM) and ensuring effective targeted herbicide application in no-till dryland cropping systems.

Mapping Riparian and Wetland Weeds with High Resolution Satellite Imagery [PDF]

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
QuickBird multi-spectral satellite imagery was evaluated for detecting weeds in waterways and wetlands in Texas. Plant species studied included giant reed (Arundo donax L.), waterhyacinth [Eichhornia crassipes (Mart.) Solms], and giant salvinia (Salvinia molesta Mitchell).

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

Applications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

MAPPING OF WEED DISTRIBUTION IN SOUTHERN KAZAKHSTAN

Experimental biology
This study presents the results of mapping the distribution of economically important and quarantine weed species in southern Kazakhstan. Field surveys were conducted in the Almaty, Zhetysu, Zhambyl, and Turkestan regions, covering agricultural lands, roadside habitats, fallow fields, and irrigated areas.

Integrating machine learning, deep learning, and image analysis for seed species classification

Applications in Plant Sciences, EarlyView.
Abstract Premise The growing demand for wildflower seeds in ecological restoration requires reliable species identification, yet current market products often contain heterogeneous species. As seed identification is labor‐intensive and requires advanced botanical knowledge, we evaluated multiple segmentation and classification approaches to determine ...

Molecular methods for differentiating Phragmites australis subspecies and identification of hybrid stands in the Upper Midwestern United States

Applications in Plant Sciences, EarlyView.
Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Kin discrimination in plants: overview and implications for population and community ecology

Biological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...
