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...

Creator:: McKinley, James Raleigh
Abstract:: Studies were conducted to determine the site of DCPA toxicity on annual ryegrass. This was done by means of a technique which used pyrex tubing and a vapor barrier to separate exposure of coleoptile and roots of emerging grass seedlings to various concentrations of DCPA. Coleoptiles that emerged through treated...

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...
