GENERAL INSTRUCTIONS

Check the crop regularly for any symptoms of disease infection. The objective of spraying is to keep the upper 2-3 leaves, ear, and stem green and functioning through grain filling. Economic responses may not be gained by spraying crops past the flowering stage. Thorough coverage of the crop is necessary for best results.

Physiological leaf spot

Physiological leaf spotting (PLS) is an abiotic disorder that occurs most frequently in barley. The development of PLS is based on genetic (varietal susceptibility) factors and environmental stresses on the crop and mostly affects the upper side of the top four leaves. TOPNOTCH® does not reduce leaf symptoms from other abiotic disorders e.g. nutritional deficiencies or toxicities, frost damage, waterlogging, drought; effects from the application of other products e.g. herbicides, foliar fertilisers, adjuvants; or damage caused by pest infestations or diseases not listed on the label. TOPNOTCH® should be used primarily for the management of fungal diseases as listed in the Directions for Use table. Reductions in the severity of PLS symptoms on treated leaves can occur when applying TOPNOTCH® at critical growth stages for disease control in barley, particularly between GS32 and GS59, prior to PLS symptom appearance. Applications of TOPNOTCH® specifically targeting reductions in PLS severity and in the absence of significant disease pressure are not recommended as this may increase the selection pressure for fungicide resistance.

Mixing

Add the required quantity of TOPNOTCH® Fungicide to water in the spray vat while stirring or with agitators in motion. Rinse the empty container with water and add rinsings to the spray tank.

APPLICATION

• Ground Application: Apply in a water volume of between 50 and 100 L/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. Aircraft should fly as low as possible under the prevailing conditions to minimize drift.
