DIRECTIONS FOR USE


IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be carefully read in order to obtain safe and successful use of this product.

Resistance
LAMAST contains folpet, a protectant fungicide from the phthalimide chemical group with multisite 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, barley and triticale
For the reduction of leaf spot (Septoria tritici/Mycosphaerella graminicola) in winter and spring wheat and triticale and leaf blotch (Rhynchosporium secalis) in winter and spring barley and triticale.
LAMAST may be applied in a programme of 2 suitably timed sprays.

Dose rate
1.5 L/ha per application
Septoria leaf spot (Septoria tritici/Mycosphaerella graminicola) in winter and spring wheat and triticale
As LAMAST 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.
Leaf blotch (Rhynchosporium secalis) in winter and spring barley and triticale
As LAMAST 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.

Water volume
Apply LAMAST in a water volume of 200-400 L/ha. As LAMAST has contact activity, it is important to achieve a good coverage of the crop when spraying.
Qualified recommendation: lower water volumes of 150 L/ha may also be used*; however, these have not been supported by effectiveness or crop safety data.
*or the equivalent of a 1% v/v dilution.

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 LAMAST 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 LAMAST as a medium spray (as defined by the BCPC) in cereals.
Thoroughly clean the sprayer and measuring equipment after using LAMAST.
Crops should not be re-entered until spray residues are dry.
