A suspension concentrate containing 47 g/l (4.0% w/w) flutriafol and 300 g/l (25.0 % w/w) chlorothalonil.
A broad spectrum fungicide for control of Septoria Leaf Spot, Yellow and Brown Rusts, Powdery Mildew and Ear Diseases of Wheat.

DIRECTIONS FOR USE
RESTRICTIONS
The maximum number of sprays of products containing flutriafol which may be applied to wheat is two.
Disease control may be reduced if strains of a pathogen less sensitive to ‘Impact Excel’ develop. Mildew populations are now less sensitive to triazole fungicides.
On some varieties of wheat, particularly those with erect leaves, high crop transpiration under some conditions can result in flag leaf tip scorch. This may be increased following application of fungicides such as ‘Impact Excel’.
This has not been shown to have a negative effect on yield or to reduce the benefits of disease control.

RECOMMENDATIONS
Diseases Controlled:
‘Impact Excel’ is recommended for use on winter wheat for the control of the late diseases leaf spot (Septoria tritici), powdery mildew, yellow rust, brown rust and the ‘late ear disease complex’.
Generally, disease control and yield benefit will be optimal when application is made at
an early stage of disease development.
Rate of Application:
2 or 2.5 litres per hectare depending on disease pressure.
Application Timing:
Impact Exel may be used at all growth stages before the beginning of flowering (Zadoks 61).
Leaf spot (Septoria tritici)
Apply when the disease is actively spreading up the crop. Optimum benefit will be gained when not more than 5% of the third leaf from the top of the plant is infected.
Yellow and Brown Rust (Puccinia striiformis and P.recondita)
Apply when the diseases are first seen to be establishing in the crop.
Optimum benefit will be gained when not more than 1% on any leaf is infected.

Powdery mildew (Erysiphe graminis)
Optimum benefit will be gained when not more than 2% of the third leaf from the top of the plant is infected.
Late ear disease complex (Cladosporium, Fusarium spp, Alternaria and Botrytis).
Treatment with ‘Impact Excel’ will also give a reduction of these late ear diseases.

MIXING AND APPLICATION
Preparation of sprayer:
Ensure that the sprayer is clean and correctly set to give even application at the required volume. Apply through conventional tractor-mounted spraying equipment as a
medium quality spray.
Mixing:
SHAKE THE CONTAINER WELL BEFORE OPENING AND USE.
Half fill the spray tank with clean water and begin agitation. Add the required quantity of ‘Impact Excel’ to the spray tank and complete filling.
Continue agitation until spray is completed.
Water Volume:
Use at least 200 litres of water per hectare at a pressure of at least 2 bar.
In dense crops increase the water volume to 250-300 litres per hectare to improve coverage.

COMPATIBILITY
A wide range of plant protection products may be tank-mixed with Impact Excel at recommended rates of use. Consult your supplier for the latest recommendations.
Before using any tank-mixture, consult and comply with the recommendations for the partner product. Each product should be added separately to the bulk of the water in the spray tank and thoroughly mixed before adding the second chemical. Agitate during completion of filling and spray immediately.
