Application Information and Resources

Application of Radial® Opti

Apply when conditions are favourable for disease development (GS21-59).

Application Volume of Radial® Opti

Ground application

Apply in a water volum of between 50 and 100L/ha using a medium quality spray. Use the higher water volume in crops with heavier canopies.

Aerial application 

Apply with suitable aircraft, set up and operated to apply fungicides to cereal crops in a water volume of between 20 and 30 L/ha using a medium quality spray. Use the higher water volume in crops with heavier canopies.

Rainfastness

Radial Opti is rainfast two hours after application for light rainfall events (≤10 mm rain), providing the spray has dried. A longer interval may be required under slow drying conditions. DO NOT apply Radial Opti if heavy rainfall (>10 mm) is forecast within four hours of application or if run-off from treated fields is anticipated within 48 hours of application.

Adjuvant Use

Radial Opti may be applied with an adjuvant for optimal disease control, residual activity and yield potential. The use of esterified seed oil adjuvants, such as Hasten* or Banjo*, or the highly refined paraffinic spray adjuvant, Biopest*, with Radial Opti can cause minor foliage damage. However, field trials have confirmed these effects do not negatively impact disease control, crop yield or grain quality.
