Multispectral fine-grained classification of blackgrass in wheat and barley crops [PDF]

Computers and Electronics in Agriculture
As the burden of herbicide resistance grows and the environmental costs of excessive herbicide use become clear, new approaches to managing weed populations are needed. This is particularly true for cereal crops, like wheat and barley, that are staple foods and occupy a globally significant share of farmland.

Spectral analysis and mapping of blackgrass weed by leveraging machine learning and UAV multispectral imagery

Computers and Electronics in Agriculture, 2022
Accurate weed mapping is a prerequisite for site-specific weed management to enable sustainable agriculture. This work aims to analyse (spectrally) and mapping blackgrass weed in wheat fields by integrating Unmanned Aerial Vehicle (UAV), multispectral imagery and machine learning techniques.

Biochemical data on blackgrass prolamines and their importance for taxonomic purposes

Biochemical Systematics and Ecology, 1981
Abstract Prolamines (alcohol-soluble proteins) were shown to occur in Alopecurus myosuroides , seeds, making up 13% of the total nitrogen. They were isolated using sequential solubility, characterized by amino acid composition, molecular weight and electrophoretic behaviour in various systems, and compared with wheat α-gliadin and oat α-avenin.

Effects of nitrogen fertilizer and emergence date on root and shoot competition between wheat and blackgrass

Weed Research, 1992
Summary: Résumé: ZusammenfassungCompetition between wheat and blackgrass (Alopecurus myosuroides Huds.) was studied in two experiments, where the effects of root competition and shoot competition were separated using an additive design. The effects of the following factors on root and shoot competition were investigated: weed density, N fertilizer ...

Factors effecting the performance of metoxuron and chlortoluron in controlling blackgrass in winter wheat

Weed Research, 1976
Summary:Blackgrass (Alopecurus myosuroides Huds.) was controlled by 2 kg/ha of metoxuron in glasshouse trials while winter wheat, cultivar Cappelle Desprez, tolerated 4 kg/ha. Blackgrass was controlled by 1.2 kg/ha of chlortoluron. Winter wheat previously damaged by freezing was injured by 2.5 kg/ha of chlortoluron applied at an early stage.
