Major changes in the 2010/2011 ‘Dog Book’
1. Active constituents
All references to carbendazim have been removed in response to the Australian Pesticides and Veterinary Medicines Authority (APVMA) directive that prohibits the use of products containing the active constituent carbendazim in Australian viticulture from the 25 JULY 2010.
It is advised that you consult your winery and/ or grape purchaser prior to the application of any carbendazim spray before 25 JULY 2010.
Products containing the active constituent procymidone have been removed from the ‘Recommendations’ tables of the ‘Dog Book’ but is still listed in the ‘Registered for use’ tables. The restriction on use in the 2009/2010 booklet still applies.
Restriction on use for export grapes: Not recommended for use on grapes destined for export wines.
Tebufenozide has been removed from the ‘Dog Book’ at the request of Dow Agrosciences who have not marketed this product since 2008. It is replaced by Prodigy which contains the active constituent methoxyfenozide.
Samurai has been granted registration by the APVMA for control of Long tailed mealybug in wine grapes.
Samurai is a Sumitomo product. It contains the active constituent clothianidin which is a group 4A insecticide.
Restriction on use for export grapes: One soil application per season, applied no later than 80% capfall.
Sumi-Alpha Flex has been granted registration by the APVMA for control of Garden weevil in grapevines.
Sumi-Alpha Flex is a Sumitomo product. It contains the active constituent esfenvalerate which is a Group 3A insecticide.
Restriction on use for export grapes: Foliar spray only. Use no later than 80% capfall.
POTASSIUM SALTS OF FATTY ACIDS
Ecoprotector has been granted registration by the APVMA for control of Botrytis in grapevines.
Ecoprotector is an Organic Crop Protectants product. It contains the active constituent potassium salts of fatty acids.
Restriction on use for export grapes: Use no later than 14 days before harvest.
A new copper active constituent copper ammonium complex has been added.
The active constituent cuprous oxide is now listed as copper cuprous oxide in alignment with the nomenclature used by CropLife Australia.
GLYPHOSATE POTASSIUM AND MONO-AMMONIUM SALTS
Roundup DST has been granted registration by the APVMA for control of a variety of weeds in vineyards. Consult the product label for details.
Roundup DST is a Nufarm product. It contains the active constituent glyphosate (present as the potassium and mono-ammonium salts) which are Group M fungicides.
2. New targets
Some products containing the active constituent metiram are now registered for use against Phomopsis cane and leaf spot. Consult the product label for details.
Some products containing the active constituent petroleum oil are now registered for use against Grape leaf blister mite. Consult the product label for details.
3. New restrictions on use
Restriction on use for export grapes: Use no later than 7 days before harvest. Consult your winery/grape purchaser before spraying within 30 days of harvest.
Restriction on use for export grapes: Use no later than E-L growth stage 31 (before bunch closure). Do not use within 60 days before harvest.
4. Resistance management strategies
CropLife Australia has a new resistance management strategy for Group 11 fungicides (quinine outside inhibitors) in Powdery mildew control. The new instructions state: DO NOT apply more than two sprays per season of Group 11 fungicides. If two consecutive applications of Group 11 fungicides are used, then they must be alternated with a fungicide from a different activity group.
The resistance management strategy for Group 11 fungicides (quinine outside inhibitors) in Downy mildew control remains unchanged, however a similar recommendation for the application of strobilurin sprays for Downy mildew control is under review by the CropLife Fungicide Resistance Management Review Group.
In the interim, it is recommended that the Powdery mildew resistance management strategy for Group 11 fungicides be employed when putting together a Downy mildew spray plan for the 2010/2011 season.
The following table lists the current off-label permits issued by the APVMA for grapevines in various situations. It is essential that you read the conditions attached to the permit prior to use.
