GROUP 4A INSECTICIDE
GROUP 3 FUNGICIDE

For the control of various insect pests and fungal diseases in a range of crops, protection against insect pests of stored cereal grains and the prevention of spread of barley yellow dwarf virus in cereal crops, as specified in the DIRECTIONS FOR USE table

GENERAL INSTRUCTIONS
Zorro may delay emergence of wheat. Crops will recover rapidly in most soil types. However, seed treated with Zorro should not be sown in soils that are likely to crust or clod at the surface after sowing. Sowing Zorro treated wheat seed deeper than 50 mm may also slightly reduce percentage plant establishment in heavier soils and sowing rates may need to be adjusted accordingly. The possible delay in emergence may counteract the advantage of suppression of Septoria tritici blotch.

Insecticide Resistance Warning
For insecticide resistance management, Zorro is a Group 4A insecticide. Some naturally occurring insect biotypes resistant to Zorro and other Group 4A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Zorro and other Group 4A insecticides are used repeatedly. The effectiveness of Zorro on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Bayer CropScience accepts no liability for any losses that may result from the failure of Zorro to control resistant insects. Zorro may be subject to specific resistance management strategies.

Fungicide Resistance Warning
Zorro is a member of the DMI group of fungicides. For fungicide resistance management the product is a Group 3 fungicide. Some naturally occurring individual fungi resistant to the product and other Group 3 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 and other Group 3 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 accepts no liability for any losses that result from failure of this product to control resistant fungi.

Seed Quality
Zorro seed treatment should not be used on seed with more than 12% moisture content, or on sprung, sprouted, damaged or severely pinched seed, or seed of poor viability. If in doubt, have a germination test carried out on the seed before treatment to ensure that it is of acceptable standard. Treating with Zorro as directed may raise the moisture level of the seed by up to 0.6%, depending on conditions at treatment. The use of Zorro at the recommended rate will have no effect on the storage life of treated sound seed.

Application
This product can be applied neat. If using container rinsings, do not exceed a total application volume (product plus water) of 600 mL/100 kg seed. Ensure good agitation of product before application to seed. Ensure proper calibration of equipment before and during application. Thoroughly coat seed. Allow seed to dry before handling.

Compatibility
Please check with your distributor or local Bayer CropScience representative before applying Zorro to pretreated seed, or in combination with other seed treatment products.

Storage Of Treated Seed
Do not store treated seed near foodstuffs or where likely to prove hazardous to humans or animals. If the seed is not used immediately after treatment it should be stored in a dry, well ventilated place. Although Zorro has no effect on the viability of treated seed, subsequent germination can be adversely affected by poor storage conditions such as high moisture combined with high temperatures. No liability can therefore be accepted for the performance of stored treated seed.

DIRECTIONS FOR USE

CEREALS
Pest / Disease: Feeding damage caused by wheat aphid and corn aphid. Spread of barley yellow dwarf virus.
State: NSW, ACT, Vic, Tas, SA, WA
Rate: 400 mL/100 kg of seed
Critical comments: Refer to ‘GENERAL INSTRUCTIONS – Application’ for application instructions.
In high risk areas (high annual rainfall) or moderate risk areas (medium annual rainfall) with the presence of high numbers of aphids following regular summer rains: A synthetic pyrethroid top-up spray should be applied 7 to 8 weeks after sowing.

Pest / Disease: Protection against insect pests of stored grains: Granary weevil (Sitophilus granarius), Indian meal moth (Plodia interpunctella), Lesser grain borer (Rhyzopertha dominica), Rice weevil (Sitophilus oryzae), Rust-red flour beetle (Tribolium castaneum), Sawtoothed grain beetle (Oryzaephilus surinamensis), Tropical warehouse moth (Ephestia cautella)
State: NSW, ACT, Vic, Tas, SA, WA
Rate: 400 mL/100 kg of seed
Critical comments: Zorro will control insect pests during the storage of cereal grains to be used for seed only. Seed treated with Zorro is not to be used for human consumption or animal feed.
