Resistência de biótipos de arroz-vermelho aos herbicidas imazapyr + imazapic e alternativas de controle

open access: yesRevista Ceres, 2014
O uso intenso de herbicidas com o mesmo mecanismo de ação na cultura do arroz (Oryza sativa L.) tem selecionado biótipos resistentes, como, por exemplo, o arroz-vermelho (planta daninha) resistente aos herbicidas imidazolinonas.

Saltcedar (Tamarixspp.) Management with Imazapyr

open access: yesWeed 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

open access: yesWeed 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

open access: yesWeed 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.

Has the Striga problem been solved? A field perspective critique of recent progress. [PDF]

open access: yesPest Manag Sci
The potential field efficacy of recently proposed breeding, biocontrol, suicidal germination, gene editing and transgenic solutions for Striga control is critically evaluated and mostly found wanting improvements. Abstract Three root‐parasitic witchweed (Striga) species can cause up to total loss of grain and legume crops for millions of farmers in ...

Behavior of soybean genotypes transformed with the AHAS gene which confers tolerance to the herbicide imazapyr

open access: yesCrop Breeding and Applied Biotechnology, 2004
The transformation of the soybean cultivars BR-16 and Doko with the AHAS gene resulted in the development of imazapyr-tolerant herbicide genotypes. A winter greenhouse trial was conducted in order to compare the conventional genotypes BR-16 and Doko with

Role of LEAFLESS, an AP2/ERF family transcription factor, in the regulation of trichome specialized metabolism. [PDF]

open access: yesNew Phytol
Summary Acylsugars, specialized metabolites produced by trichomes of many solanaceous species, provide protection against biotic and abiotic stresses. Many acylsugar metabolic enzymes have been identified; however, regulatory factors remain unknown.

Residues and Dissipation of the Herbicide Imazapyr after Operational Use in Irrigation Water. [PDF]

open access: yesInt J Environ Res 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 ...

Development of transgenic imazapyr-tolerant cowpea (Vigna unguiculata) [PDF]

open access: yesPlant Cell Reports, 2013
Here we present the development of cowpea lines tolerant to a herbicide from imidazoline class (imazapyr). Plants presented tolerance to fourfold the commercial recommended dose for weed control. Cowpea is one of the most important and widely cultivated legumes in many parts of the world.

Effects of the herbicide imazapyr on juvenile Oregon spotted frogs [PDF]

open access: yesEnvironmental Toxicology and Chemistry, 2012
Abstract Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater-breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs.
