Impact of glyphosate, imazapic, and metsulfuron on bahiagrass, vaseygrass, and guineagrass control
Weed TechnologyBahiagrass, guineagrass, and vaseygrass are dominant weeds in bermudagrass pastures. Chemical control of these weeds is difficult, as some herbicides damage bermudagrass. The objectives of this study were to assess the effect of glyphosate and glyphosate

Herbicide toxicity to Nitrospirillum amazonense: assessing bacterial survival and microbial functionality. [PDF]
Pest Manag SciHerbicides elicit a spectrum of responses in Nitrospirillum amazonense, ranging from the stimulation of metabolic functions (biological nitrogen fixation, IAA production) to significant growth inhibition and acute toxicity. Abstract BACKGROUND Herbicides can exert significant toxicity on nontarget organisms, including plant growth‐promoting bacteria ...
