Stabilan 750SL is a plant growth regulator for use on wheat, barley, oats and perennial ryegrass seed crops.

NEW Registration for use in barley 

  • A plant growth regulator for use on wheat, barley, oats and perennial ryegrass seed crops
  • Suitable for use in wheat and oat crops as a straw shortener (by up to 20%) and to manage the risk of neck break and lodging to improve yields.
  • Reduced eyespot susceptibility.
  • In ryegrass seed crops it can be used to promote seed yield by synchronising tiller growth and increasing tiller survival.


Active Ingredient: 750g/L Chlormequat-chloride


Formulation: Soluble concentrate


General Information

Stabilan 750 SL is absorbed by the leaves and acts on the developing stem, shortening and thickening the internodes. This can reduce the risk of stem break and lodging, improve uniformity of crop development and reduce eyespot susceptibility. In intensive cereal growing it allows for optimum use of nitrogen fertilizers. Leaf area is increased and colour enhanced. Stabilan 750 SL can provide root growth and the number of fertile tillers, which may increase yield even in the absence of lodging. Response to Stabilan 750 SL may vary with variety, but a height reduction of 20% is typical.


Directions for use

Timing: Only use Stabilan 750 SL on crops which are growing satisfactorily, without stress and under fertile conditions. Time of application is very important. Stabilan 750 SL should be applied as close as possible to the earliest recommended tmiing. Application at early growth stages may be less effective if unfavourable weather after spraying slows down the plant growth. Application after the second node is detectable is too late and little or no effect will be observed.
Correctly determine the cereal growth stage by selecting 10 plants at random across the field. It is necessary to split tillers to determine the presence of the first node (GS31). When done by “feel” only, what appears to be the first node is actually closer to second node detectable (GS32) stage. At Zadoks GS31 the head will be visible above the third node, the third and second nodes will be a few millimeters apart, and the second and first nodes MUST be less than 2cm apart. [Refer to FAR Arable Update Cereals No 132 (Aug 2003) for precise description of Zadoks growth stages.]
