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.

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.

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.

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.

Herbicide Phytotoxicity Model for Assessing Herbicide Tolerance
Journal of Agronomy and Crop Science, 1988AbstractA herbicide phytotoxicity model was used to investigate differences in herbicide tolerance between two species of Amsinckia (A. intermedia Fischer and Meyer and A. gloriosa Suksdorf) to the herbicide bromoxynil (3,5‐dibromo‐4‐hydroxybenzonitrile).

Publisher Summary This chapter appraises substituted phenylurea herbicides. They are a group of pesticides used for general weed control in agricultural and nonagricultural practices—for example, along railroads, utilities, rights- of-way, and in industrial areas.
