Application of commercial formulations of bromoxynil (emulsion concentrate, and/or suspension concentrate) in the ecosystem may induce species shifts within the communities and could affect the structure and the function of the aquatic communities [6].

In addition, Australia and New Zealand report that further information to certain pesticides may be obtained on protocols developed by Canada, which used data mainly from animal toxicology studies and provide a table containing the maximum values allowed in this country to the animals drinking water for aldicarb, bromoxynil, carbofuran, cyanazine, chlorothalonil, dicamba, diclofop-methyl, dimethoate, dinoseb, glyphosate, simazine, tebuthiuron, triallate and trifluralin (ANZECC, 2000).

Weed control was achieved with trifluralin (all crops) and simazine (lupin only), and post-emergent applications of bromoxynil (wheat) and fusilade (canola) were used when required.
In another study, Sims and collaborators discovered that the soil bacterium Desulfitobacterium chlororespirans can degrade the herbicides bromoxynil and ioxynil--and a common metabolite of bromoxynil--under anaerobic conditions.
Annual broadleaf weeds were controlled postemergence with commercial formulations of thifensulfuron [3-(4-methoxy-6-methyl-1,3,5-triazin-2-ylcarbamoylsulfamoyl) thiophene-2-carboxylic acid] (14 g ai [ha.sup.-1]), tribenuron {2-[4-methoxy-6-methyl-1,3,5-triazin-2-yl(methyl)carbamoylsulfamoyl] benzoic acid} (7 g ai [ha.sup.-1]), and 2,4-D ester (140 g ai [ha.sup.-1]) on 24 May 1999, and with bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) (560 ai [ha.sup.-1]), and MCPA (4-chloro-o-tolyloxyacetic acid) (560 ai [ha.sup.-1]) on 29 May 2000 and 1 June 2001.
For both sites, herbicides were applied post emergence before weeds and cover crops reached 8-cm height to minimize competitive interactions with the growing corn: Pursuit (imazethapyr) at 0.11 kg [ha.sup.-1] (1.44 oz [ac.sup.-1]) and Buctril (bromoxynil) at 1.16 L [ha.sup.-1] (1.5 pts [ac.sup.-1]).
