Role Of Tordon

“DESULTS obtained to date on blackberry, sweet briar, gorse and eucalypts have shown Tordon to be more active than presently accepted herbicides,'* says R. H. Ferguson writing in a Dow publication, “Biokemia."

“The employment of Tordon in mixture with 2, 4-D and 2,4,5-T appears worthy of further investigation as a means of improving the costefficiency ratio. Admixtures have in certain instances given results superior to those obtained with Tordon. alone. "Tordon herbicide applied alone and in combination with 2,4-D or 2,4,5-T has proven very active against blackberry, including species normally considered tolerant to 2,4,5-T. “It is obvious from the investigations so far conducted that Tordon or mixtures of Tordon and 2,4,5-T can be re-

garded as a probable alternative to 2,4,5-T ester alone for the control of gorse in New Zealand. "Results to date indicate that Tordon is very active against sweet briar and is the only compound so far evaluated in New Zealand which will completely suppress regrowth from large (200 stem> bushes in the first growing season following application. "In AurtroMk Tordon plus 2,4-D in the ratio of 021 b Tordon plus o.oolb 2,4-D per 100 gallons gave complete nil of sweet briar when applied as a leaf stem spray to active growth. Similar results have been obtained in New Zealand with the use of mist blower application. Mixtures of Tordon with 2,4,5-T also appear to offer economic advantages over applications of straight Tordon herbicide at the higher rate of application required for similar control.”
