Creator:: Duke, William B.
Abstract:: Atrazine, atratone and ametryne are asymmetric s-triazine herbicides used pre- and post-emergence on many crops. Under conditions unfavorable for microbial activity, these compounds may persist in the soil for long periods of time. This study was conducted to determine the influence of the soil microflora upon atrazine, atratone and ametryne...

Abstract:: Atrazine is an asymmetrical s-triazine herbicide used pre- and post-emergence for the control of weeds in many crops. Under conditions considered unfavorable for microbial activity, atrazine may persist in soils for extended periods of time. However, the significance of chemical versus microbial degradation is not known. This study was conducted...

Abstract:: The effect of Endothal (3, 6-endoxyhexahydrophthalic acid), sodium pentachlorophenate (Na-PCP) and TD-47 (di-N, N-dimethylcocoamine salt of Endothal) on the microbial populations, ammonification, nitrification and respiration in six different soils was investigated. It was found that Endothal at 20 and 200 ppm had no adverse effect on the microbial population, ammonification,...

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...
