Hydrolysis and biological degradation of atrazine in soils

Creator:

Skipper, H. D. (Horace D.)

Abstract:

Detoxification of atrazine in soils results from both chemical hydrolysis and microbial degradation. Infrared analysis was used to study the hydrolysis of atrazine upon interaction with soil colloids and to ascertain the existence of enol, keto, and protonated-keto forms of hydroxyatrazine. Evolution of ¹⁴CO₂ from ¹⁴C-atrazine and ¹⁴C-hydroxyatrazine was indicative...

Surfactant effects on bromacil and picloram adsorption by Oregon soils

Creator:

Gaynor, John Donald

Abstract:

The physical and chemical properties of soils greatly affect the toxicity of bromacil and picloram. Consequently, a knowledge of the parameters which influence the soil inactivation of these herbicides is necessary to determine proper application rates for good weed control. Enhancement in phytotoxicity with the addition of surfactants or surface...
