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.

Evaluation of cropping systems for management of herbicide-resistant populations of blackgrass (Alopecurus myosuroides Huds.)

Crop Protection, 2001
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 ...

Effects of seed production and storage conditions on blackgrass (Alopecurus myosuroides) germination and shoot elongation

Weed Science, 2003
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 a single plant and its consequences on weed infestation

Ecological Modelling, 2001
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, 1974
Summary: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).

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 ...
