    Roundup uses the active ingredient glyphosate. Different formulations of Roundup (and mimics from other companies) utilize different surfactants and other additives, but in every case it is glyphosate doing the dirty work.

    This French study shows that a mixture of 4 pesticides (glyphosate, atrazine, aminomethyl phosphoric acid (AMPA), desethyl-atrazine (DEA)) exhibited the most potent cytogenetic toxicity, which was fold higher than those of the most active compound AMPA, and fold increased after light-irradiation. Hack-and-squirt treatments are most commonly used in hardwood forest timber stand improvement projects to deaden undesirable “cull” trees and invasive tree species, such as tree-of-heaven. These applications are often used to help establish desirable regeneration by removing low shade cast by dense understories of undesirable saplings and.

    Hexazinone is an organic compound that is used as a broad spectrum herbicide. It is a colorless solid. It exhibits some solubility in water but is highly soluble in most organic solvents except alkanes. A member of the triazine class herbicides, it is manufactured by DuPont and sold under the trade name Velpar. It functions by inhibiting photosynthesis and thus is a nonselective herbicide Appearance: White crystalline solid. Under the conditions of this study, herbicide formulations containing Accord Concentrate (glyphosate), Arsenal AC (imazapyr), Chopper (imazapyr), Escort (metsulfuron methyl), Oust XP (sulfometuron methyl), and Velpar L (hexazinone) were not associated with appreciable acute toxicity to fathead minnows or C. dubia when used alone or in mixtures Cited by:

GBHs themselves are chemical mixtures; in addition to the inclusion of glyphosate (the active ingredient), these herbicides include adjuvants such as surfactants, which can make GBH-product formulations more toxic than glyphosate alone [42–44].

Hexazinone is used against many annual, biennial, and perennial weeds, as well as some woody plants. It is mostly used on non-crop areas; however, it is used selectively for the control of weeds among sugar cane, pineapples, and rangeland forage.

For sites with more vigorous weed growth, hexazinone offers better knockdown and residual activity, but at a higher cost. Hexazinone is a water-soluble compound and is predominantly root-absorbed, with some foliar absorption.
