Biochemical data on blackgrass prolamines and their importance for taxonomic purposes
Biochemical Systematics and Ecology, 1981Abstract 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.

In the growing season 2002-2003 two field experiments were carried out in winter wheat on the heavy clay soil of the coastal polder area at Zevekote to study the response of blackgrass (Alopecurus myosuroides Huds.) resistant or somewhat less sensitive to a wide variety of herbicides (clodinafop-propargyl, fenoxaprop-P-ethy1; flupyrsulfuron-methyl ...

A blackgrass population has developed resistance to fenoxaprop-P-ethyl following field selection with the herbicide for 6 consecutive years. Within this population, 95% of the individuals are also resistant to flupyrsulfuron. Both the inheritance(s) and the mechanism(s) of resistances were investigated by making crosses between the resistant and a ...

Whole-plant glasshouse experiments were conducted to examine herbicide resistance in selected populations of blackgrass (Alopecurus myosuroides HUDS.). Three populations with either non-target-site resistance (NTSR) or target-site resistance (TSR) showed reduced sensitivity to the herbicides fenoxaprop and mesosulfuron + iodosulfuron.

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.

Abstract Simplification of cropping systems often leads to an increase in weed populations which require an intensive use of herbicides to maintain populations at an acceptable level. Due to a heavy reliance on herbicides and a lack of cultural control measures, herbicide-resistant blackgrass (Alopecurus myosuroides Huds.) biotypes appeared recently ...

Abstract Blackgrass is a common winter annual grass weed in autumn-sown crop rotations in Atlantic European countries. Control with a minimum amount of herbicides in integrated cropping systems would be facilitated by modeling the effect of cropping systems on its demography.

Blackgrass (Alopecurus myosuroides Huds.) seed dispersal from single mother-plants was studied in two experiments. For the first experiment, eight blackgrass plants of different heights and number of ears were produced in a greenhouse with the help of different in sowing densities and nitrogen nutrition levels.

Survey of the presence of wild oat and blackgrass in parts of the United Kingdom
Weed Research, 1974Summary:The survey was carried out over an area representing about 47% of the cereal acreage of the United Kingdom.Estimates of the acreage of fields containing wild oat (Avena fatua L. and A. ludoviciana Dur) ranged from 15% (Northern Ireland) to 74% (England, South West Region).

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 ...
