GROUP 9 FUNGICIDE
For the control of grey mould (Botrytis cinerea) including fungal strains resistant to dicarboximides and benzimidazoles, in grapevines, strawberries and tolerant ornamental species
Fungicide Resistance Warning
Scala 400 SC Fungicide is a member of the anilinopyrimidine group of fungicides. For fungicide resistance management Scala is a Group 9 fungicide.
Some naturally occurring individual fungi resistant to Scala and other Group 9 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungi population if these fungicides are used repeatedly. These resistant fungi will not be controlled by Scala and other Group 9 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 Scala to control resistant fungi.
Resistance Management Strategy
Scala is a Group 9 fungicide. CropLife resistance management strategies restrict the use of sprays containing Group 9 fungicides. Sprays of fungicides from other chemical groups may also be restricted by CropLife resistance management strategies and/or specific product label requirements and these should be considered when planning a grey mould control program.
For Scala and other Group 9 fungicides;
1. If three or fewer grey mould sprays are applied in a season, use only one spray per season containing a Group 9 fungicide. If four or more grey mould sprays are applied use no more than two sprays containing Group 9 fungicides.
Alternate applications of Group 9 containing fungicides with effective fungicides from other fungicide groups.
2. Late season fungicide treatments should be applied before grey mould infection reaches unacceptably high levels in the vineyard.
3. DO NOT apply more than two consecutive sprays from the same fungicide group, including from the end of one season to the next.
1. Apply a program of protectant fungicides during flowering. Only use Scala if conditions favour disease development during this period.
2. Avoid applying more than two successive sprays of Scala (or other Group 9 fungicides), including from the end of one season to the next.
3. If three or fewer grey mould fungicide sprays are applied per crop, use only one Scala (or other Group 9 fungicide) spray. If four to six sprays are applied per crop use a maximum of two sprays of Scala (or other Group 9 fungicides). If seven or more sprays are applied per crop use a maximum of three Scala (or other Group 9 fungicide) sprays.
Export of Treated Produce
Growers should note that suitable MRLs or import tolerances may not be established in all markets for fruit treated with Scala 400 SC Fungicide. If you are growing strawberries for export or grapes for export (either fresh, dried or as wine), please check with Bayer CropScience Pty Ltd or the Australian Wine Research Institute (in the case of wine), for the latest information on MRLs and import tolerances BEFORE using Scala.
Add the required amount of Scala directly to the half-filled spray tank with agitators in motion, or with constant mechanical agitation.
Complete filling of spray tank under constant agitation. Do not allow the spray mixture to remain in the tank for long periods without agitation.
NOT to be applied by aircraft.
Grapevines - Scala can be applied using suitable dilute or concentrate ground application equipment. Equipment should produce a spray that ensures penetration of the canopy and coverage of the flowers or bunches.
Strawberries - Scala can be applied using suitable high or low volume application equipment. Equipment should produce a spray that ensures penetration of the canopy and coverage of the flowers and/or fruit.
Grapevines - Refer to Special Instructions for Grapevines.
Strawberries - Use water volumes of 350 to 1000 L/ha depending on equipment and crop stage to ensure adequate penetration of the canopy and coverage of foliage and flowers and/or fruit.
IMPORTANT - Apply only to field-grown ornamentals or to plants grown in well-ventilated plastic tunnel houses or glass houses. Application in enclosed areas with poor ventilation, and high humidity, may cause phytotoxicity to flowers and foliage of some ornamental species.
Special Instructions for Grapevines
- Use a sprayer designed to apply high spray volumes, up to the point of run-off and matched to the crop being sprayed.
- Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient spray volume to cover the crop to the point of run-off. Avoid excessive run-off.
- The required spray volume to achieve point of run-off may be determined by applying different test volumes, using different settings on the sprayer, or from industry guidelines or other expert advice.
- Add the amount of product specified in the Directions for Use table for each 100 L of water. However, if greater than 1000 L/ha is required to achieve point of run-off, adjust the amount of product added for each 100 L of water to ensure no more than 2.0 L/ha product is applied. Spray to the point of run-off.
- The required dilute spray volume to achieve point of run-off will change and the sprayer set up and operation may also need to be changed, as the crop grows.
- Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies spray volumes less than those required to reach the point of run-off) and matched to the crop being sprayed.
- Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen spray volume.
- Based on your chosen spray volume per hectare, and the amount of product specified in the Direction for
Use table for each hectare, calculate the mixing rate for concentrate spraying.
- The chosen spray volume and the sprayer set up and operation may need to be changed as the crop grows.
- For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.
For use on grapevines, Scala is compatible with most commonly used fungicides and insecticides including; Bacillus thuringiensis, dimethoate, Bayfidan®, Blue Shield® DF, Lorsban® WP, mancozeb, Mycloss®, Oxydul®, ProGibb®, Ridomil® Plus, Spin® Flo and wettable sulphur. Do not mix Scala with products exhibiting alkaline reaction, including lime sulphur and Bordeaux mixtures. When mixing Scala with Bayfidan, use butyl gloves. Mixtures with Foli-R-Fos® may cause leaf damage.
DIRECTIONS FOR USE
DO NOT apply to ornamentals without prior tolerance testing of each species/variety (refer to Critical Comments)
DO NOT apply to ornamentals grown in poorly ventilated glasshouses or plastic tunnel houses
Disease: Grey mould (Botrytis cinerea)
Dilute Spraying: 200 mL/100 L water (maximum 2.0 L/ha)
Flowering*: 1.5 to 2.0 L/ha
Post-flowering: 2.0 L/ha
Refer to the Application section in GENERAL INSTRUCTIONS
Critical comments: Applications should be made at the critical timings for botrytis control.
Note: This use is subject to a CropLife Resistance Management Strategy. Refer to ‘Resistance Management Strategy – Grapevines’ under General Instructions for guidelines.
Apply by dilute or concentrate spraying equipment. Use a sufficient amount of water and/or adequate equipment to ensure penetration of the canopy and coverage of the flowers or bunches.
May be used with a non-ionic wetting agent.
* For concentrate spraying at flowering use the high rate on dense canopies or when conditions favour disease.
Disease: Grey mould (Botrytis cinerea)
Rate: 2.0 L/ha
Critical comments: Apply Scala during flowering when conditions favour disease development. Repeat at 7 to 10 day intervals alternating with a fungicide of a different chemical group. Use the shorter application interval when disease pressure is high.
Note: This use is subject to a CropLifeResistance Management Strategy, which governs the maximum number of applications per season. Refer to ‘Resistance Management Strategy – Strawberries’ under General Instructions for guidelines.
Use water volumes of 350 to 1000 L/ha depending on equipment and crop stage to ensure adequate penetration of the canopy and coverage of foliage and flowers and/or fruit. May be used with a non-ionic wetting agent.
