Disease: Septoria tritici 

Rate: Apply 2 litres ENVOY in 200 to 300 litres of water per hectare.

Critical Comments:C

 

ENVOY contains pyraclostrobin, a member of the QoI cross resistance group. ENVOY should be used preventatively and should not be relied on for its curative potential.

When curative activity is needed apply QoI fungicides in mixture with a suitable dose of a curative fungicide from a different cross-resistance group. ENVOY meets this requirement as it contains epoxiconazole. To ensure the effectiveness of the epoxiconazole component as a partner, ENVOY should always be applied at the full recommended rate.

Envoy contains epoxiconazole, a DMI fungicide. Resistance to some DMI fungicides has been identified in Septoria leaf blotch (Mycosphaerella graminicola) which may seriously affect the performance of some products. For further advice on resistance management in DMIs contact your agronomist or specialist advisor, and visit the FRAG-UK website.

Use ENVOY as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action. You must not apply more than two foliar applications of QoI containing products to any cereal crop.

There is a significant risk of widespread resistance to QoI cross resistance group fungicides occurring. Failure to follow resistance management action may result in reduced levels of disease control.

 

ENVOY is approved for use in winter and spring wheat, durum wheat, winter and spring barley, oats, rye and triticale.

Apply ENVOY at the start of foliar disease attack. A maximum of two applications can be made before grain watery ripe in winter and spring wheat, durum wheat, rye and triticale and up to and including emergence of ear just complete in winter and spring barley and oats.

Apply 2 litres ENVOY in 200 to 300 litres of water per hectare.

If required water volumes down to 100 litres per hectare may be used, however these have not been supported by effectiveness or crop safety data.

 

After treating a cereal crop with ENVOY onions, oats, sugar beet, oilseed rape, cabbages, carrots, sunflowers, barley, lettuce, ryegrass, dwarf French beans, peas, potatoes, clover, wheat, field beans and maize may be sown as the following crop.

The effect of Envoy on other crops has not been assessed.

 

Never prepare more spray solution than is required.

Half fill the spray tank with clean water and start the agitation. SHAKE THE CONTAINER WELL before use and pour in the required amount of product. Rinse any empty containers thoroughly and add rinsings to the spray tank. Add the remainder of the water and continue agitation until spraying is completed. Spray solution MUST be used on the day of mixing and must NOT be left overnight.

When tank mixes are to be used, take due note of any instructions given as to the order of mixing. Each product should be added separately to the spray tank and fully dispersed before the addition of any further product(s).

All tank mixes should be used immediately after mixing.

On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or by manually rinsing three times. Add washings to tank at time of filling and dispose of container safely.
