A fungicide for protection against leaf blotch (Zymoseptoria tritici) on wheat and leaf blotch (Rhynchosporium secalis) on barley.
A suspension concentrate formulation containing 500 g/l (39.5% w/w) folpet. Contains folpet and hexamethyl tetramine: may produce an allergic reaction.

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.

RESISTANCE
COLORADO contains folpet, a protectant fungicide from the phthalimide chemical group with multi-site contact activity. For resistance management purposes,
it’s mode of action is classified as M4 under the FRAC* code which indicates low-risk without any signs of resistance or cross-resistance developing.
For current advice on resistance management contact your agronomist or specialist advisor, and visit the FRAG-UK website.
Disease control in wheat and barley For the reduction of leaf spot (Zymoseptoria tritici) in winter and spring wheat and leaf blotch (Rhynchosporium secalis) in winter and spring barley. COLORADO may be applied in a programme of 2 suitably timed sprays.

Dose rate
1.5 L/ha per application

Septoria leaf spot (Zymoseptoria tritici) in winter and spring wheat
As COLORADO is a protectant fungicide with contact activity, it is important to apply the first spray before the disease becomes established in the crop (normally GS 30-33). A second spray should be timed to protect new growth from disease and therefore needs to be applied prior to further infection. This is normally 3 weeks after the first application, but may be sooner under conditions of rapid growth and high disease pressure. Where disease infection or reinfection has occurred prior to application, COLORADO should be mixed with alternative chemistry, e.g. epoxiconazole, to provide curative activity (see Compatibility section).

Leaf blotch (Rhynchosporium secalis) in winter and spring barley
As COLORADO is a protectant fungicide with contact activity, it is important to apply the first spray before the disease becomes established in the crop (normally
GS 30-33). A second spray should be timed to protect new growth from disease infection. This is normally 3 weeks after the first application, but may be sooner
under conditions of rapid growth and high disease pressure. Where disease infection or reinfection has occurred prior to application, COLORADO should be mixed with alternative chemistry, e.g. epoxiconazole, to provide curative activity (see Compatibility section).

Water volume
Apply COLORADO in a water volume of 200-400 L/ha. As COLORADO has contact activity, it is important to achieve a good coverage of the crop when spraying.

Mixing and spraying
For use by tractor mounted/trailed sprayer only. Before spraying it is important to check all hoses, filters and nozzles, and to ensure that the sprayer is clean and correctly calibrated to give an accurate application at the correct volume. Half-fill sprayer tank with clean water. Add the required amount of COLORADO to the water and commence agitation.
On emptying the container, RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely. Add the remainder of the water whilst continuing to agitate the mixture until spraying is complete.
Apply COLORADO as a medium spray (as defined by the BCPC) in cereals. Thoroughly clean the sprayer and measuring equipment after using COLORADO.
Crops should not be re-entered until spray residues are dry.

Compatibility
COLORADO may be tank-mixed with ‘Opus’ or ‘Cortez’ which must be applied at the recommended rate of use against these diseases.
Maintain agitation during the mixing process and continue until the spraying is complete. Do not leave in spray tank for long periods without using.

Caution
After spraying a herbicide, sprayer tanks and equipment should be thoroughly cleaned before using COLORADO.
