THE ADSORPTION OF IMAZAPYR BY THREE SOIL TYPES IN INDONESIA

BIOTROPIA
The adsorption of imazapyr in three Indonesian soil types was investigated with labelled 14 C-imazapyr using Freundlich adsorption isotherm. The availability of adsorbed imazapyr to plants as affected by washing and liming was assayed using root elongation of rice seedlings. Red-Yellow Podsolic soil adsorbed imazapyr more than Andosol and sandy soil of

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 ...

Root exudation of imazapyr by eucalypt, cultivated in soil Exsudação radicular de imazapyr por eucalipto cultivado em solo

Planta Daninha, 2004
Imazapyr has been used to control stump sprouting in stand of Eucalyptus plantations, where herbicide is applied to the tree trunk before cutting. The herbicide is applied exclusively on the stump to be killed, but little is known about the final fate of the molecule. Imazapyr exudation via roots of eucalypt grown in soil as the substrate was evaluated
