applied alone, the combination is said to be synergistic ( Colby, 1967 ). However, a tank-mixed application could also result in reduced control under certain circumstances; such combinations are said to be antagonistic. Glyphosate has been used for

Growers and landscapers are often faced with weed problems in ornamentals that cannot be controlled with selective herbicides. In landscape situations, glyphosate is mainly used as a nonselective herbicide. However, researchers have reported that

Glyphosate, a foliar applied, broad-spectrum herbicide was discovered in 1970 and commercialized in 1974 ( Franz et al., 1996 ). Since then, glyphosate use has increased rapidly, and it has become the most popular herbicide worldwide ( Baylis, 2000

The development of two glyphosate-tolerant PRG cultivars, JS501 and Replay, provides a unique avenue for weed control ( Samudio et al., 2011 ). A previous field trial established these cultivars can tolerate glyphosate rates up to 0.81 kg·ha −1

Glyphosate [N-(phosphonomethyl)-glycine] is a systemic, nonselective, postemergence herbicide that controls more weed species than any other herbicide ( Duke, 2018 ; Heap and Duke, 2018 ). It has been used to control annual, perennial, and biennial

Weed and insect pest management in agronomic crops has changed dramatically since commercialization of transgenic glyphosate [ N -(phosphonomethyl)glycine]-resistant (GR) cultivars in the 1990s. The ability to use glyphosate, a nonselective
