IT’S TOO COLD TO APPLY GROWTH REGULATORS WITHOUT ARMA

• Many winter wheat crops were drilled early and the majority are well-tillered and forward in their development. These advanced crops will be at high risk of lodging later in the season.
• This year also a high proportion of the wheat varieties currently being grown are prone to lodging. Deben and Glasgow have a 4 rating to lodging, with Xi19 having a rating of only 5. Claire, Option, Istabraq and Gladiator have a 6 rating to lodging. In addition several key varieties such as Deben, Solstice and Xi19 are tall with a low centre of gravity.
• These crops will need early and effective growth regulation at stem extension stage (GS31-32) to reduce crop height and to strengthen the stem.

Arma Will Optimise Uptake In Cold Conditions

• But uptake of growth regulators at this time of year will not be optimal. The minimum temperature for best effectiveness of chlormequat is 8°C, whereas the average temperature in the early spring months is 5.3°C.
• Adding Arma to early growth regulators will improve their effectiveness and flexibility.
• In development work Arma has been shown to increase the uptake of chlormequat at four fold when applied at 4°C and two fold at 12°C.

Arma Will Increase Penetration & Uptake

• For products less affected by temperature, such as Moddus and Meteor, Arma will also offer considerable benefits in terms of penetration and uptake.

Arma Benefits Right Across The Tank Mix

Arma will also benefit all components in the tank-mix – contact fungicides, triazoles fungicides, strobilurin fungicides, growth regulators, broad-leaved weed herbicides and grass-weed sulphonyl urea herbicides.
