The Synthesis and Biological Activity of 1-Alkyl-4-(3-azacyclobenzoyl)-5-hydroxypyrazole Herbicides

CHIMIA, 2003
The benzoylpyrazoles belong to a class of herbicides that inhibit the enzyme 4-hydroxy-phenylpyruvate dioxygenase (HPPD). This mode of action is characterized by bleaching due to the disruption of plastoquinone and ?-tocopherol biosynthesis ...

Production of organic seed for the organic sector (OF0154) [PDF]

, 2000
This is the final report of Defra project OF0154. Under the European Union Regulation on the organic production of agricultural products (2092/91), crops raised in organic systems should be grown from organically produced seed or vegetative material ...

Modelling the effect of spatially variable soil properties on the distribution of weeds [PDF]

, 2019
The patch spraying of weeds is an area of precision agriculture that has had limited uptake. This is in part due to the perceived risks associated with not controlling individual weeds.

Upscaling miscanthus production in the United Kingdom: The benefits, challenges, and trade‐offs

GCB Bioenergy, Volume 16, Issue 8, August 2024.
Miscanthus is considered a key biomass crop for sustainable energy generation, carbon capture, and storage in the United Kingdom. Significant upscaling of domestic biomass production will be required to remove historic carbon emissions from the atmosphere to mitigate climate change. This review examined the current evidence regarding land availability,

Management of inflorescence and viable seed production of blackgrass (Alopecurus myosuroides) on set-aside in France [PDF]

, 2001
International audienceTwo experiments were carried out, one in a glasshouse and the other in the field, to assess the effect of weeding management (type and date) on blackgrass seed production during set-aside.

Quantifying the impacts of management and herbicide resistance on regional plant population dynamics in the face of missing data

Journal of Applied Ecology, Volume 61, Issue 5, Page 1109-1126, May 2024.
As we demonstrate that high herbicide resistance levels can produce extremely severe weed infestations, monitoring herbicide resistance is a priority for farmers across Western Europe. Furthermore, developing non‐chemical control methods is essential to control current weed populations, and prevent further resistance evolution.

WeedScout: Real-Time Autonomous Blackgrass Classification and Mapping Using Dedicated Hardware

Blackgrass (Alopecurus myosuroides) is a competitive weed that has wide-ranging impacts on food security by reducing crop yields and increasing cultivation costs. In addition to the financial burden on agriculture, the application of herbicides as a preventive to blackgrass can negatively affect access to clean water and sanitation.

Improving the Availability of Organic Forage Seed in Wales [PDF]

, 2004
The EU regulation requiring organic farmers to use 100% organic herbage seed is looming closer. Currently they are ‘enjoying’ a derogation from this because suitable seed is not available. For 2004 seeds mixtures had to contain at least 50% organic seed.

Plant Glutathione Transferases: Structure, Antioxidant Catalytic Function and in planta Protective Role in Biotic and Abiotic Stress [PDF]

, 2015
Plant cytosolic glutathione transferases (GSTs) belong to an ancient enzyme superfamily with multiple and diverse functions which are important in counteracting biotic and abiotic stress.

Resistance of blackgrass (Alopecurus myosuroides Huds.) to ALS inhibitors in region of south-western Poland

Progress in Plant Protection, 2022
The aim of the research was to identify resistant and sensitive biotypes of Alopecurus myosuroides to various substances from the ALS inhibitors group and to determine the degree of resistance to these compounds in south-western Poland. The experiments were performer by the method of biological tests.
