Abiotic degradation (photodegradation and hydrolysis) of imidazolinone herbicides.
J. Environ. Sci. Health B 43(2) , 105-12, (2008) The abiotic degradation of the imidazolinone herbicides imazapyr, imazethapyr and imazaquin was investigated under controlled conditions. Hydrolysis, where it occurred, and photodegradation both followed first-order kinetics for all herbicides. There was no h... |

Acetohydroxyacid synthase (AHAS) in vivo assay for screening imidazolinone-resistance in sunflower (Helianthus annuus L.).
Plant Physiol. Biochem. 61 , 103-7, (2012) The objective of this work was to evaluate the in vivo acetohydroxyacid synthase (AHAS) activity response to imidazolinones and its possible use as a selection method for evaluating AHAS inhibitor resistance. In vivo AHAS assay and the comparison of parameter... |

Faster degradation of herbicidally-active enantiomer of imidazolinones in soils.
Chemosphere 79(11) , 1040-5, (2010) Imidazolinones are chiral herbicides, comprised of two enantiomers with differential herbicidal activity. In this study, the selective degradation of enantiomers of the three imidazolinone herbicides, imazapyr, imazethapyr and imazaquin, was determined in a v... |

Poor competitive fitness of transgenically mitigated tobacco in competition with the wild type in a replacement series.
Planta 222(2) , 372-85, (2005) Transgenic crops can interbreed with other crop cultivars or with related weeds, increasing the potential of the hybrid progeny for competition. To prevent generating competitive hybrids, we previously tested tobacco (Nicotiana tabacum L.) as a model for vali... |

Enantiomeric separation of imidazolinone herbicides using chiral high-performance liquid chromatography.
Chirality 19(3) , 171-8, (2007) Chiral high-performance liquid chromatography (HPLC) is one of the most powerful tools to prepare enantiopure standards of chiral compounds. In this study, the enantiomeric separation of imidazolinone herbicides, i.e., imazethapyr, imazapyr, and imazaquin, wa... |

Biolistic-mediated genetic transformation of cowpea (Vigna unguiculata) and stable Mendelian inheritance of transgenes.
Plant Cell Rep. 27 , 1475-1483, (2008) We describe a novel system of exploiting the biolistic process to generate stable transgenic cowpea (Vigna unguiculata) plants. The system is based on combining the use of the herbicide imazapyr to select transformed meristematic cells after physical introduc... |

Development of transgenic imazapyr-tolerant cowpea (Vigna unguiculata).
Plant Cell Rep. 32(4) , 537-43, (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 legum... |

Mineralization of herbicides imazapyr and imazaquin in aqueous medium by, fenton, photo-fenton and electro-fenton processes.
Environ. Technol. 29(5) , 489-96, (2008) Oxidative degradation of aqueous solutions of imazapyr and imazaquin herbicides at room temperature and pH 3.0 has been investigated by Fenton, photo-Fenton and electro-Fenton processes. The high degradation power of these advanced oxidation processes is due ... |

Dissipation of four forest-use herbicides at high latitudes.
Environ. Sci. Pollut. Res. Int. 15(7) , 573-83, (2008) Large-scale deforestation is occurring in subarctic North America following clearing by salvage logging or insect attack. Numerous shrubs, herbs, and deciduous tree species tend to dominate areas on which stands of white spruce have grown. In the absence of e... |

Effects of the herbicide imazapyr on juvenile Oregon spotted frogs.
Environ. Toxicol. Chem. 32(1) , 228-35, (2013) 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 t... |
