Summary: MCPA, mecoprop, dichlorprop, dicamba, 2,3,6‐TBA, bentazone, ioxynil/bromoxynil (a mixture), barban, difenzoquat and chlorfenprop‐methyl were applied by spinning disc in controlled drop sizes from 150‐350μm and at very low volume rates (5–45 1/ha), to the foliage of some dicotyledonous weed species or wild oats ( Avena fatua L.). The same herbicides were also applied by means of conventional hydraulic nozzles at volume rates of about 200 1/ha. Most of these herbicides performed as well at very low volume rates as with the conventional application, the major exceptions being bentazone, ioxynil/bromoxynil (both of which have distinct contact effects) and dichlorprop. Comparisons between oil and water as the diluent at a very low volume rates suggest that there may be situations when oil is preferable and others when water is.
