Are you familiar with phenoxies?
If you aren’t, you might be surprised at just how relevant they are.
The term phenoxies is an umbrella title for a group of herbicides that mimic the effect of natural plant hormones called auxins. Auxins are only found in plants and regulate growth, one of their functions is to make the plant grow towards the light.
When phenoxies such as MCPA, CMPP-P and 2,4-D mimic auxins mode of action, they cause the target weed to thicken and twist, effectively causing it to grow rapidly in a way that is detrimental to the weed. Due to this unique mode of action replicating a plants natural growth system, phenoxies aren’t as affected by resistance issues in broad-leaf weeds. Products containing previously mentioned phenoxies such as MCPA are selective in grass and cereals in addition to a range of additional crops. Another group of phenoxies, called butyrics (2,4-DB / MCPB) are also selective in many clovers and legumes.

Nufarm knows phenoxies
At a global level Nufarm is a key player in the production of phenoxy herbicides. Over the years we’ve prided ourselves in the production of phenoxies, with two manufacturing sites based directly in Europe, situated in both Linz, Austria and Wyke, UK. Our Wyke site, just outside Bradford, is the largest flexible phenoxy production site in the world and we’re proud to say that a lot of the phenoxy products we provide here in the UK are British made.
Why are phenoxies more relevant than ever?
With resistance management being an important factor in today’s agricultural climate, phenoxies are well suited to help agronomists and growers help manage resistance issues. The demise of several active ingredients in recent years has left fewer options for broad-leaved weed control in cereals. This lack of new herbicide modes of action, combined with a heavy reliance on sulphonylureas in winter and spring cereals has led to the development of ALS resistance in some broad-leaved weeds.
However, phenoxies combined with sulphonylureas in tank mixes can provide wide spectrum of control over broad-leaved weeds, such as adding fluroxypyr or florasulam to a mix, to give an added effect of cleaver control.
