Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]

open access: yesNew Phytologist, 2009
Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.

On herbicidal actions

The Bulletin of Mathematical Biophysics, 1948
A theoretical interpretation of the herbicidal action of the 2,4-Dichlorophenoxyacetic acid is suggested.

Herbicides and Cancer

JNCI: Journal of the National Cancer Institute, 1992
Herbicides are a heterogeneous class of chemicals used in agriculture, forestry, and urban settings to kill weeds, shrubs, and broad-leaved trees. The role of herbicides in the etiology of cancer is controversial. Potential studies for review were identified through a MEDLINE search and from a check of references in related review articles.

Diaryloxyacetate herbicides

Pest Management Science, 2002
AbstractThe discovery and investigation of a novel family of herbicides containing a diaryl acetal are described. The stability of the acetal limited herbicidal efficacy and recognizing that fact led to the design of analogs with commercial levels of post‐emergence activity on broadleaf weeds.

Herbicide Formulations

Journal of Toxicology: Clinical Toxicology, 2000
Herbicides comprise nearly half of the 5 billion pounds of pesticide active ingredients used worldwide annually. The active ingredient must be formulated with other ingredients to allow mixing, dilution, application, and stability. Liquid commercial formulations for spray foliar application include water-soluble liquids, emulsifiable concentrates ...

Herbicide‐resistant crops and weed resistance to herbicides

Pest Management Science, 2005
AbstractThe adoption of genetically modified (GM) crops has increased dramatically during the last 3 years, and currently over 52 million hectares of GM crops are planted world‐wide. Approximately 41 million hectares of GM crops planted are herbicide‐resistant crops, which includes an estimated 33.3 million hectares of herbicide‐resistant soybean ...

Effects of Herbicides on Flowering

Environmental Toxicology and Chemistry, 2020
Abstract Herbicides have been shown to reduce flower production and to delay flowering, with results varying among herbicides and tested plant species. We investigated the effects of herbicides on flowering in an extensive greenhouse study conducted in Canada and Denmark.

Analysis of Herbicides

Angewandte Chemie International Edition in English, 1974
AbstractHerbicides, like other pesticides, leave undesirable residues on the treated plants. To analyze them, the plant material is extracted and the herbicidal residues are separated from the bulk of the co‐extractives of natural origin, about which too little is known.

Current state of herbicides in herbicide‐resistant crops

Pest Management Science, 2014
AbstractCurrent herbicide and herbicide trait practices are changing in response to the rapid spread of glyphosate‐resistant weeds. Growers urgently needed glyphosate when glyphosate‐resistant crops became available because weeds were becoming widely resistant to most commonly used selective herbicides, making weed management too complex and time ...
