Leaching and residual activity of imidazolinone herbicides in lowland soils

Ciência Rural
: Herbicides used in the Clearfield® rice (Oryza sativa L.) production system have a potential for leaching. This can result in contamination of underground water resources and cause injury to not tolerant crops that are sown in a succession and/or crop ...

Rhizoma peanut root‐rhizome mass, growth, and decomposition under grazing or clipping management

Crop Science, Volume 65, Issue 3, May/June 2025.
Abstract Belowground plant structures are integral to nutrient cycling in grassland ecosystems. However, relative to herbage responses, few studies have examined the belowground dynamics of warm‐season perennial forages under different management practices.

Castor (Ricinus communis L.) Tolerance to Postemergence Herbicides and Weed Control Efficacy

International Journal of Agronomy, 2012
Potential US castor production is limited due to only one labeled herbicide (trifluralin). Field studies were conducted at two Texas locations during 2008 and 2009 to evaluate postemergence herbicides for castor tolerance and weed control efficacy ...

Echinochloa crusgalli var. Mitis metabolism as resistance mechanism to imazapyr and imazapic

Acta Agronómica, 2020
Selection pressure caused by continuous use of imazapyr and imazapic herbicides in rice fields without crop rotation, has selected for resistant biotypes of Echinochloa crusgalli var. mitis. To know the mechanism of resistance involved becomes important in order to define effective management strategies.

Residual Effect of Imidazolinone Herbicides on Emergence and Early Development of Forage Species in Rice-Livestock Systems

International Journal of Plant Biology
The intensification of rice–livestock systems has encouraged the integration of forage species into rice cultivation. However, the use of imidazolinone-tolerant rice cultivars (imazapyr + imazapic, IMIs), essential for weedy rice control, may hinder the ...
