Water Environment Research, 2009
This is a review of literature published in 2008 that covered issues related to the presence of pesticides and herbicides in the environment. The review is divided into nine sections, including analytical methods, toxicology, monitoring, ecology, fate and transport, modeling, risk assessment, management and minimization, as well as treatment strategies.

Herbicides based on pelargonic acid: Herbicides of the bioeconomy
Biofuels, Bioproducts and Biorefining, 2019AbstractFollowing the first generation of natural herbicide products based on pelargonic acid as an active ingredient, a number of new herbicides and blossom thinners based on C9:0 saturated fatty acid entered the marketplace in many countries, offering a long‐awaited safer alternative to synthetic chemical herbicides.

Herbicide‐resistant crops and weed resistance to herbicides
Pest Management Science, 2005AbstractThe 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 ...

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.

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.

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 ...

This chapter describes the reproductive and developmental toxicity of herbicides and fungicides in humans and animals. Numerous chemicals including herbicides and fungicides are ubiquitous in the environment. Some of them obviously have the potential to cause reproductive and developmental toxicity.

Effects of Herbicides on Flowering
Environmental Toxicology and Chemistry, 2020Abstract 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.

Current state of herbicides in herbicide‐resistant crops
Pest Management Science, 2014AbstractCurrent 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 ...

Herbicide Detoxification: Herbicide Selectivity in Crops and Herbicide Resistance in Weeds
2005Crop selectivity is important in allowing weeds to be controlled by herbicides without damage to the crop. Often tolerant crops have more rapid and complete detoxification of a herbicide than occurs in sensitive crop species and weeds. A number of enzymatic systems are able to detoxify herbicides in plants.
