GROUP 4A INSECTICIDE

For the control of various insect pests 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
Insecticide Resistance Warning
For insecticide resistance management, Gaucho is a Group 4A insecticide. Some naturally occurring insect biotypes resistant to
Gaucho 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 Gaucho and other Group 4A insecticides are used repeatedly. The effectiveness of Gaucho 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 Gaucho to control resistant insects. Gaucho may be subject to specific resistance management strategies.

Export of treated produce
Growers should note that MRLs or import tolerances do not exist in all markets for edible produce treated with Gaucho. If you are growing edible produce for export, please check with Bayer CropScience Pty. Ltd. for the latest information on MRLs and import tolerances before using Gaucho.

Mixing
Flowable formulations will settle over time. Prior to pouring or pumping Gaucho from the container, either shake container
vigorously or operate pump by-pass to ensure thorough mixing of the contents. When preparing mixtures the following mixing
order applies: flowable fungicides, coating agents (e.g. Peridiam) then Gaucho and stir until homogeneous. Add any emulsifiable liquid last whilst slowly stirring.

Application
Calibrate commercial seed treatment equipment to ensure the seed throughput is mixed with the correct dose of slurry seed treatment. Ensure the seed treatment mixture is applied to the maximum number of seeds when initially applied to the seed. Retain seed in mixing chamber until good seed to seed coverage is achieved. Do not overmix seed as a detrimental effect on treatment quality may result.
Use a range of 400 mL - 600 mL of total volume (e.g. Gaucho plus water) with each 100 kg of seed. Do not use a volume of more than 600 mL with each 100 kg of seed.

Sowing of treated seed
Check flow rate of seed through sowing machinery before sowing to ensure the desired seeding rate is achieved. Drilling for seed sowing is recommended.

Seed quality
Gaucho 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 Gaucho as directed may raise the moisture level of the seed by up to 0.6%, depending on conditions at treatment.

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 Gaucho 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. Gaucho used as directed will have no effect on the storage life of treated sound seed.

DIRECTIONS FOR USE

FABA BEANS
Pest:
Aphids
Rate: 120 mL/100 kg of seed
Critical comments: Gaucho will protect seedlings from early season aphid infestation. Gaucho does not affect the viability of rhizobia when Gaucho is mixed with inoculant.

FIELD PEAS
Pest:
Aphids
Rate: 60 mL/100 kg of seed
Critical comments: Gaucho will protect seedlings from early season aphid infestation. Gaucho does not affect the viability of rhizobia when Gaucho is mixed with inoculant.

LENTILS
Pest:
Aphids
Rate: 240 mL/100 kg of seed
Critical comments: Gaucho will protect seedlings from early season aphid infestation. Gaucho does not affect the viability of rhizobia when Gaucho is mixed with inoculant.

CANOLA
Pest:
Aphids, Redlegged earth mite, Blue oat mite
Rate: 400 mL/100 kg of seed
Critical comments: Gaucho will protect canola seedlings from early season aphid damage.

LUPINS
Pest: 
Redlegged earth mite, Blue oat mite
Rate: 300 mL/100 kg of seed
Critical comments: Gaucho will protect emerging seedlings for 3 -4 weeks after sowing. Crops must be monitored in the first 4 weeks of emergence to ensure Gaucho performance.
For autumn sowing: After a pasture phase sow Gaucho treated seed following a well timed spring spray (prior to the development of diapause eggs) of Le-mat® 290 SL Insecticide. After a cropping phase a spring spray is not usually required, however if monitoring in spring finds moderate mite populations, a spring spray should be applied.
For spring sowing: After a pasture phase apply a spray of Le-mat prior to sowing Gaucho treated seed.
Gaucho does not affect the viability of rhizobia when Gaucho is mixed with inoculant and seed is sown immediately into a moist soil.

CEREALS
Pest:
Feeding damage caused by wheat aphid and corn aphid
Rate: 120 or 240 mL/100 kg of seed
Critical comments: Use higher rate for increased length of control and in areas of high risk.

Pest: Spread of barley yellow dwarf virus
Rate: 120 or 240 mL/100 kg of seed
Critical comments: In high risk areas with over 500 mm rain or moderate risk areas with over 400 mm rain in seasons following summer rains, a synthetic pyrethroid top-up spray should be applied 7 to 8 weeks after sowing.

Pest: 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)
Rate: 120 mL/100 kg of seed
Critical comments: Gaucho will control insect pests during the storage of cereal grains to be used for seed only. Seed treated with Gaucho is not to be used for human consumption or animal feed.
