Teach Your Broadleaf Weeds a Unique Chemistry Lesson with Crop Care’s Affinity
Affinity 400DF is the only post emergent Group G selective herbicide available on the Australian market. It is used for the post-emergent control of broadleaf weeds in cereals and was developed by Crop Care Australasia .
With its unique mode of action, Affinity 400 DF is particularly effective against brassica weeds in cereals, showing rapid activity on major weed problems such as wild radish. Affinity 400 DF is a useful tool for farmers and agronomists who are structuring a broadleaf resistance management package on farm.
Doug Nuttall, Technical Sales Representative with Crop Care, says Affinity is recognised as a broad spectrum alternative with proven efficacy and very fast activity on major broadleaf weeds. “Affinity offers a new mode of action – Group G – for broadleaf weed control, which is a valuable alternative to current chemistry for the control of wild radish and other broadleaf weeds where resistance has been detected,” he said.
“Affinity can play a key role in properly planned rotations to alleviate some of the selection pressure on broadleaf herbicides currently used in cereals.” Mr Nuttall said that Affinity is a contact herbicide which is highly effective at low rates. Last year an additional 10 weeds were added to the Affinity label. “When used in combination with MCPA amine (Thistlekillem), a wide range of 27 key broadleaf weeds are controlled,” Mr Nuttall said.
This tank mixture also provides two modes of action, reducing the risk of resistance while providing the broadest weed control spectrum. “Agronomists in Western Australia who have already seen Affinity at work in the paddock recognise it as a very fast acting post-emergent herbicide which is safe to use on cereals such as wheat, barley, oats and triticale,” Mr Nuttal said.
Affinity 400 DF is available in a convenient WG formulation containing 400 g/kg carfentrazone-ethyl. At recommended rates, Affinity has no soil activity and there are no crop rotation restrictions on the label.
Mr Nuttall emphasised that because of its very fast speed of activity on broadleaf weeds, Affinity is not suitable for applying with crop oil concentrates or blended oil/surfactant adjuvants or for mixing with grass selective herbicides. “We recommend that where required, the grass selective herbicide is sprayed first, followed by Affinity 10 days later,” he said.
