GROUP 11 FUNGICIDE
For the control of certain diseases of bananas as specified in the DIRECTIONS FOR USE table.
Fungicide Resistance Warning
Flint 500 SC is a member of the strobilurin group of fungicides. For fungicide resistance management Flint 500 SC is a Group 11 fungicide. Some naturally occurring individual fungi resistant to the product and other Group 11 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungal population if these fungicides are used repeatedly. These resistant fungi will not be controlled by this product or other Group 11 fungicides, thus resulting in a reduction in efficacy and possible yield loss. Since the occurrence of resistant fungi is difficult to detect prior to use, Bayer CropScience Pty Ltd accepts no liability for any losses that may result from the failure of this product to control resistant fungi.
Integrated Pest Management
Flint 500 SC is suitable for use in IPM programmes. Flint 500 SC is harmless to predators in situations where integrated mite control is practised.
DO NOT mix Flint 500 SC with any additive other than high quality (narrow-range) water miscible mineral crop oils. As formulations of mineral spray oils are beyond the control of Bayer CropScience please refer to Bayer CropScience, your chemical reseller, aerial applicator or the manufacturer of the oil to ensure that it is physically and biologically compatible with Flint. IMPORTANT – if using Flint with a mineral crop oil in crops with exposed (un-bagged) bunches, please refer to the Special Warning section following.
There are certain conditions when the surface of recently emerged fruit is particularly prone to marking damage from spray applications. In circumstances where application will be made to very rapidly growing fruit in hot conditions with strong direct light, it is recommended that all emerged bunches be bagged prior to spraying to minimise risk of fruit marking. If using Flint with a mineral oil in blocks with un-bagged bunches, please contact Bayer CropScience, your chemical reseller or aerial applicator for up to date information regarding the oil formulations recommended by Bayer CropScience.
Mixing and Application
Add the required amount of product to half of the water in the spray tank. Then add the water miscible mineral crop oil (if using) and the remainder of the water and mix well. If the banana crop is destined for export, the bananas should be bagged prior to spraying to ensure that MRLs of trifloxystrobin are below the MRLs for export destinations.
Apply at least 20 L of spray mixture per hectare for aerial application. DO NOT apply within 10 metres upwind of aquatic areas including, natural streams, rivers and waterways.
Mixing difficulties may occasionally be encountered when using low application volumes in combination with very soft water. The problem can be readily alleviated by the addition of a suitable buffering agent to the spray tank.
Export of Treated Produce
Maximum Residue Limits (MRLs) may be lower or not be established in export markets. Check with your Industry Association or Bayer CropScience prior to using this product on crops destined for export. Bagging of bunches prior to spraying will reduce the likelihood of detectable residues occurring in bananas.
DIRECTIONS FOR USE
State: Qld, NSW, WA & NT only
Disease: Yellow Sigatoka, black Sigatoka, cordana leaf spot
Rate: 150 mL/ha (plus a high quality water miscible mineral crop oil at up to 5 L/ha*)
Critical comments: This use is subject to a CropLife resistance management strategy.
Flint should be applied as part of a regular program of fungicide sprays, alternating with fungicides from different chemical groups. For optimum disease control maintain thorough de-leafing practices, in accordance with industry guidelines, to reduce disease inoculum. Old leaves, and leaves with advanced lesions should be removed, or infected parts of the leaf removed, prior to the application of Flint.
Intervals between fungicide applications generally should be 14-21 days, but should be modified for locality, disease conditions, and leaf emergence growth rates.
Flint should be diluted with sufficient water to ensure thorough coverage of all leaf surfaces (minimum 20 L/ha spray volume when applied by air).
*When conditions are favourable for disease development, a high quality (narrow-range) mineral crop oil should be applied with Flint. Refer to the Compatibility section of the label for information on mineral crop oils. Use the maximum rate of oil appropriate to the conditions at time of spraying, up to 5 L/ha. Flint should only be applied without oil during dry conditions or when disease pressure is low.
Do not apply consecutive Flint applications. Apply a minimum of 2 sprays from a different activity group, e.g. Folicur® 430 SC, between sprays of Flint or other Group 11 fungicides. In the Tropics (North Qld, NT and Northern WA) DO NOT apply Group 11 sprays in the months of May, June, July, August and September. Apply a maximum of 4 applications of Flint (or other Group 11 fungicides) to any banana block in a 12-month period. Flint should not be used where foliar diseases are in an advanced stage of development.
