Root exudation of imazapyr by eucalypt, cultivated in soil [PDF]
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

Residues and Dissipation of the Herbicide Imazapyr after Operational Use in Irrigation Water [PDF]
International Journal of Environmental Research and Public Health, 2020 Imazapyr is a herbicide that can be used in irrigation canals to control a range of aquatic weed species, however, its residual nature, combined with its phytotoxicity to crops at low concentrations, means that the water in canals must be carefully managed following imazapyr application.

Copper(II) Complexes of the Imidazolinone Herbicide Imazapyr
Journal of Agricultural and Food Chemistry, 1996 The copper(II) complexes formed by the imidazolinone herbicide imazapyr [(±)-2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinic acid] were studied in aqueous solution by potentiometric and spectroscopic techniques. Imazapyr acts as a chelating molecule and is effective over a wide pH range.

Saltcedar (Tamarixspp.) Management with Imazapyr
Weed Technology, 1998 During the 20th century, naturalized saltcedar has become common within major tributaries throughout the western United States. Often growing in nearly monocultural stands, saltcedar is suspected of lowering water tables, thus destroying wetlands and wildlife habitats.

Impact of Imazamox and Imazapyr Carryover on Wheat, Barley, and Oat
Weed Technology, 2017 Imazapyr and imazamox are frequently applied postemergence to control grass and broadleaf weeds in imidazolinone-resistant sunflower in Argentina. Herbicide carryover to rotational crops represents a disadvantage of these herbicides, particularly in regions with low rainfall during the months prior to rotational crop sowing.

Effect of Ammonium Sulfate, Imazapyr, and Environment on the Phytotoxicity of Imazethapyr
Weed Technology, 1991 The effects of 1.24 kg ha-1ammonium sulfate, 5 g ae ha-1of the isopropylamine salt of imazapyr, and air temperature of 18, 27, and 35 C at 40 and 100% relative humidity on the phytotoxicity of 35 g ae ha-1of the ammonium salt of imazethapyr applied postemergence to pitted morningglory were evaluated.

Development of lawns in response to applications of imazapic alone or combined with imazapyr
Revista Brasileira de Engenharia Agrícola e Ambiental, 2021 Successive mowings are the major maintenance cost of lawns. These costs have led to the search for alternatives to mechanical management. This study aimed to determine the effects of imazapic herbicide doses applied alone or combined with imazapyr as a ...
