To the Editor.— We were very interested in the article 1 and accompanying editorial 2 concerning herbicide exposure and cancer risk that appeared in the Sept 5 issue of JAMA . It has been our informal experience that the incidence of lymphoma in our rural, agriculturally based community has been higher than expected.

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. This review

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.

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 ...

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.

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.

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 ...
