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 ...

Arroz tolerante a imidazolinonas: controle do arroz-vermelho, fluxo gênico e efeito residual do herbicida em culturas sucessoras não-tolerantes Imidazolinone tolerant rice: red rice control, out-crossing and herbicide carryover to non-tolerants crops

Planta Daninha, 2006
Após várias décadas de busca de alternativas para controle do arroz-vermelho, desenvolveram-se genótipos de arroz tolerantes a herbicida do grupo químico das imidazolinonas, o qual controla eficientemente esta planta daninha no Sistema Clearfield.

An investigation of vascular discolouration in potato tubers (Solanum tuberosum L.) treated with imazethapyr

, 1998
This thesis describes work undertaken to determine the effect of imazethapyr on the morphology and physiology of stored potato tubers. Imazethapyr is an effective sprout suppressant, providing control at least equivalent to industry standards, and the ...

Hoary Cress (Cardaria draba) Management with Imazethapyr

, 1999
Currently, there are no effective herbicides registered for the control of hoary cress (Cardaria draba) in alfalfa (Medicago sativa) or alfalfa/grass mixtures. Due to this lack of control options, field experiments were conducted near St.

Study on the Enantioselective Degradation of Imazethapyr in Soil by CE

, 2008
A method was developed for the separation of imazethapyr enantiomers using capillary electrophoresis and large volume injection. Optimized buffer conditions were found using 6% hydroxypropyl-beta-cyclodextrin as the chiral selector at pH 11 with an ...
