Registration of Tx3499–Tx3503 sorghum germplasm resistant to acetyl‐coenzyme A carboxylase‐inhibiting herbicides

Journal of Plant Registrations, Volume 19, Issue 1, January/April 2025.
Abstract The sorghum [Sorghum bicolor (L.) Moench ssp. bicolor] germplasm lines Tx3499–Tx3503 (Reg. no. GP‐948–Reg. no. GP‐952, PI 706257–PI 706261) were developed by the Texas A&M AgriLife Research sorghum breeding program in 2024. These lines are resistant to acetyl‐coenzyme A carboxylase (ACCase)‐inhibiting herbicides used for post‐emergence control

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 ...

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.

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.

Economics of herbicide‐free crop production

Applied Economic Perspectives and Policy, Volume 46, Issue 4, Page 1692-1716, December 2024.
Abstract Ambitious pesticide policies aiming to reduce pesticide applications and risks have been introduced across Europe. Herbicides represent a major part of pesticide use, but the uptake of mechanical or agronomic alternatives remains low. We here explore underlying reasons and provide policy insights for supporting a transformation to herbicide ...

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.

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,
