Controls certain post-harvest diseases in citrus, pome fruit, stone fruit, kiwi fruit, mangoes and pomegranates

DIRECTIONS FOR USE

CITRUS
Disease: Blue Mould (Penicillium italicum), Green Mould (Penicillium digitatum), Diplodia Stem End Rot
Rate: 
Dip and high volume: 260 to 520 mL in 100 L water
Low volume: 87 to 174 mL per 10,000kg fruit applied in 5 to 15 L water
Critical Comments: Raising the temperature of the prepared aqueous solution to a maximum of 50°C for up to 1 minute may improve the efficacy of this product. Avoid long heat exposure on fruit with sensitive rind.
Applied alone Scholar should be used in alternation with other products for easily protected fruit and when disease pressure is expected to be low to moderate. Under high disease pressure, Scholar should only be used with other postharvest fungicides (see Compatibility section).
Refer to Application section below for application instructions.

KIWI FRUIT
Disease: Grey Mould (Botrytis cinerea)
Rate: 
Dip and high volume: 130 to 260 mL in 100 L water
Low volume: -
Critical Comments: Refer to Application section below for application instructions.

MANGOES
Disease: Anthracnose (Colletotrichum gleosporoides), Stem end rot and Dendritic spot (Botrosphaeria family and includes Fusicoccum parvum, Dothiorella dominicana, Lasiodiplodia theobromae and Phomopsis mangiferae)
Rate: 
Dip and high volume: 60 to 120 mL in 100 L water (52°C for 5 minutes)
Low volume: -
Critical Comments: Hot dip or flood spray.
Use the low rate for low disease pressure and the high rate for high disease pressure.
Refer to Application section below for application instructions.

Disease: Anthracnose (Colletotrichum gleosporoides)
Rate: 
Low volume: 260 mL /100 L
Critical Comments: Low volume non-recirculating spray only.

POME FRUIT
Disease: Blue Mould (Penicillium expansum & P. solitum), Grey Mould (Botrytis cinerea)
Rate: 
Dip and high volume: 130 to 260 mL in 100 L water
Low volume: -
Critical Comments: Refer to Application section below for application instructions.

POMEGRANATES
Disease: Botrytis fruit rot (Botrytis cinerea)
Rate: 
Dip and high volume: 260 mL in 100 L water
Low volume: -
Critical Comments: Dip or flood spray. Fruit should be dipped or drenched under high volume application for 30 seconds.
The dip or flood spray may be heated to 49°C to further increase efficacy.

STONE FRUIT – except Apricots and Peaches
Disease: Brown Rot (Monilinia spp.), Grey Mould (Botrytis cinerea), Rhizopus Rot (Rhizopus stolonifer)
Rate: 
Dip and high volume: 130 to 260 mL in 100 L water
Low volume: -

STONE FRUIT – Apricots and Peaches
Disease: Brown Rot (Monilinia spp.), Grey Mould (Botrytis cinerea), Rhizopus Rot (Rhizopus stolonifer)
Rate: 
Dip and high volume: 130 mL in 100 L water
Low volume: -

Critical Comments: Refer to Application section below for application instructions.

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION

WITHHOLDING PERIOD
NOT REQUIRED WHEN USED AS DIRECTED

GENERAL INSTRUCTIONS
Scholar is a protective fungicide used as a post-harvest treatment to control certain post-harvest diseases. Scholar may be applied as a post-harvest dip, drench, flood or spray in citrus and mangoes, or as a dip or drench in pome fruit, pomegranates, stone fruit and kiwi fruit.
Note: SCHOLAR may be degraded by exposure to direct sunlight. Treated fruit should not be stored in direct sunlight.

Mixing
Clean mixing and spraying equipment before use. Prepare no more treatment solution than is needed for the immediate operation. Shake the container before use to ensure uniform dispersion of contents before measuring quantity required. Half-fill the spray or mixing tank with clean water or wax/oil emulsion (or aqueous dilution of a wax/oil emulsion) and start agitation. While filling the remainder of the spray tank add the required amount of SCHOLAR. Begin application of the solution after SCHOLAR has completely and uniformly dispersed into the mix carrier. Maintain agitation throughout the treatment operation. DO NOT let the treatment mixture stand overnight in the tank. Flush the spray equipment thoroughly after each use.

Application
Dip and High Volume Drench Application
Citrus, kiwi fruit, pome fruit, pomegranates and stone fruit: Dip fruit in prepared solution for 30 to 60 seconds and allow fruit to drain. Ensure fruit is in complete contact with the dipping solution.
Mangoes: Apply by hot dip or hot flood spray. Time of exposure: 5 minutes at 52°C.

High Volume Application
Mix appropriate volume of SCHOLAR (see Directions for Use) in water, wax/oil emulsion, or aqueous dilution of a wax/oil emulsion for the fruit being treated. Use T-Jet, flooders, or similar application system. Fruit should be treated for approximately 30 seconds. Ensure all parts of fruit are well covered by mixture.

Low Volume Application
Citrus: Apply by low volume application. Use properly calibrated low volume application equipment. Ensure all parts of fruit are well covered by the spray solution and application time is at least 30 seconds. Mix the required amount of Scholar in 5 to 15 L of water or wax per 10,000 kg fruit.
Mangoes: Apply by low volume non-recirculating ambient spray, exposing fruit for 30 seconds. The use of brush rollers may improve efficacy.

Compatibility
SCHOLAR Fungicide can be mixed with Tecto®, imazalil (eg Fungaflor*), calcium hypochlorite and DPA. A reduction in efficacy may occur when Scholar is applied with DPA at DPA rates above 500 ppm.
If tank mixes are to be used observe all directions, precautions and limitations on all products to be used.
As formulations of other manufacturer’s products are beyond the control of Syngenta, and the quality of water may vary with location, all mixtures should be tested prior to mixing commercial quantities.

Cleaning Equipment
Rinse application equipment with water after use. Spread rinsings over flat land away from desirable vegetation, waterways and drainage, and follow Dip Disposal instructions.

GROUP 12 FUNGICIDE

Fungicide Resistance Warning
SCHOLAR Fungicide is a member of the phenylpyrrole group of fungicides. For fungicide resistance management SCHOLAR is a Group 12 fungicide. Some naturally occurring individual fungi resistant to SCHOLAR and other Group 12 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 SCHOLAR and other Group 12 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, Syngenta Australia Pty Ltd accepts no liability for any losses that may result from the failure of SCHOLAR to control resistant fungi.

Export of Treated Produce
While Maximum Residue Limits (MRLs) have been set in many major export destinations, it should be noted that MRLs or import tolerances may not be established in all export destinations. For further information regarding export tolerances please contact your export organisation or Syngenta Australia representative.
