Stabilan 750SL plant growth regulator is now approved for use in barley, as well as wheat, oats and perennial ryegrass seed.
Sonja Vreugdenhil, Nufarm technical specialist, says the label extension comes in time for autumn sown crops that will start to become reproductive in early spring, as well as those going in the ground soon.
In either case, Stabilan750SL can be applied at the start of the stem elongation process during a narrow window between Zadoks GS30 and GS32.
Correct timing is imperative, she says. Applications at or after GS32 will have little to no impact, so it’s important that fast-growing crops are walked frequently to assess growth stage.
“Spring sown barley crops tend to grow very quickly. If you don’t walk these crops for a week, you can easily miss a growth stage.”
Used as directed, Stabilan750SL thickens and shortens the developing barley stem by up to 20%, which can in turn reduce the risk of stem or neck break and lodging, lead to more uniform crop development with less straw put through the header, and reduce susceptibility to eye-spot.
Instead of having to limit fertiliser to reduce the risk of lodging, growers of intensive crops can use Stabilan 750SL to optimise nitrogen inputs for yield.
“It can promote root growth and the number of fertile tillers, which may increase yield even in the absence of lodging,” Sonja adds.
Stabilan 750SL is compatible with most fungicides including Joust.
