DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
Comet 200 is a fungicide with protectant and curative properties for disease control in winter and spring wheat, winter and spring barley and oats.
Comet 200 is a fungicide with protectant properties for disease control in maize (forage and grain).
In cereals yield response may be obtained in the absence of visual disease.
In maize a grain yield response may be obtained in the absence of visual disease.
Comet 200 can maintain the total greenness of the crop towards the end of the growing season.  
 
Restrictions/Warnings
Extreme care must be taken to avoid drift onto nearby crops.
Wash equipment thoroughly after use.
You must not apply more than two foliar applications of QoI containing products to any cereal crop.
 
Disease Control
Comet 200 is a fungicide with protectant and curative properties for disesase control in winter and spring wheat, winter and spring barley and oats. Comet 200 is a fungicide with protectant properties for disease control in maize (forage and grain). Details are summarised below:
 
WINTER WHEAT, SPRING WHEAT
Disease:Septoria tritici
Rate:Apply 1.25 litres Comet 200 in a minimum of 200 litres of water per hectare.
Critical Comments: Comet 200 is recommended for control of S. tritici with moderate curative ability in the latent phase.
Disease:Septoria nodorum
Rate:Apply 1.25 litres Comet 200 in a minimum of 200 litres of water per hectare.
Critical Comments:Comet 200 is recommended for control of S. nodorum with best results achieved when used as a protective treatment or during early stages of disease establishment.
Disease:Yellow rust
Rate:Apply 1.25 litres Comet 200 in a minimum of 200 litres of water per hectare.
Critical Comments:C
Disease:Brown rust
Rate:Apply 1.25 litres Comet 200 in a minimum of 200 litres of water per hectare.

Critical Comments:MC
(C = Control MC = Moderate Contro)
 
Resistance Management
Comet 200 contains pyraclostrobin, a member of the QoI cross resistance group. Comet 200 should be used preventatively and should not be relied on for its curative potential.
On cereal crops, Comet 200 must always be used in mixture with another product, recommended for control of the same target disease that contains a fungicide from a different cross resistance group and is applied at a dose that will give robust control.
Use Comet 200 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 occurring in Septoria tritici populations in the UK. Failure to follow resistance management action may result in reduced levels of disease control.
 
Crops
Comet 200 is a fungicide with protectant and curative properties for disease control in winter and spring wheat, winter and spring barley and oats.
Comet 200 is a fungicide with protectant properties for disease control in maize (forage and grain).
Time of Application
Cereals
Apply Comet 200 at the start of foliar disease attack. A maximum of two applications can be made before grain watery ripe in winter and spring wheat and up to and including emergence of ear just complete in winter and spring barley and oats.
Maize (Forage and Grain)
Best results are achieved by an application of Comet 200 before the start of foliar disease attack or at the very earliest signs of infection.
Comet 200 gives control of Eyespot for up to seven weeks after application when applied before the start of foliar disease attack.
If applying before the start of disease attack, it is recommended to only treat sites that have a known history of disease when conditions are conducive for disease development. It is recommended to consult with a specialist maize agronomist before application.
 Once established in the crop Comet 200 can reduce the development of the disease. Application can be made up to and including mid-flowering.
Rate of Application
Cereals Apply 1.25 litres Comet 200 in a minimum of 200 litres of water per hectare.
Maize (Forage and Grain) Apply 1.0 litres Comet 200 in 200-400 litres of water per hectare.
 
Mixing and Spraying
Apply as a MEDIUM spray, as defined by BCPC.
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.
When tank mixes are to be used, each product should be added separately to the spray tank.
All tank mixes should be used immediately after mixing.
