GENERAL INSTRUCTIONS
Larvin 375 is a non-systemic insecticide, which means that new growth appearing after application will not be protected against insect attack.
This product is an aqueous suspension concentrate formulation that readily disperses in water for spraying by ground or air equipment. It is unstable under highly acidic or highly alkaline conditions, being hydrolytically sensitive to degradation of active constituent by strong acids, strong bases and certain heavy metals and salts.
DO NOT apply when weather conditions favour drift from the area to be treated.
Larvin is only moderately rainfast - rain within 3 hours of application may reduce the effectiveness of this product.

Insecticide Resistance Warning
For insecticide resistance management, Larvin 375 Insecticide is a Group 1A insecticide. Some naturally occurring insect biotypes resistant to Larvin 375 and other Group 1A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Larvin 375 or other Group 1A insecticides are used repeatedly. The effectiveness of Larvin 375 on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Bayer CropScience Pty Ltd accepts no liability for any losses that may result from the failure of Larvin 375 to control resistant insects.
Larvin 375 may be subject to specific resistance management strategies. For further information contact your local supplier, Bayer CropScience representative or local agricultural department agronomist.

Export of Treated Produce
Growers should note that suitable MRLs or import tolerances may not be established in all markets for produce treated with Larvin 375 Insecticide. If you are growing produce for export, please check with Bayer CropScience Pty Ltd for the latest information on MRLs and import tolerances BEFORE using Larvin 375 Insecticide.

Mixing
Agitate or shake container prior to use. Remove oil, rust, scale, pesticide residues and other foreign matter from sprayer and strainer. Flush with clean water. Use 50 mesh or slotted strainer in spray system. Fill tank approximately half full of water, add this product and mix thoroughly by mechanical or hydraulic action. Add water to desired volume and thoroughly mix again.

Application
This product may be applied by air or ground equipment. Use a minimum prepared spray volume of 20 L/ha by air (30 L/ha for cotton, 50 L/ha for maize or sweetcorn) and 50 L/ha by ground. A droplet density of a minimum 60 droplets per cm2 must be attained. There needs to be some air movement, which preferably should be blowing across the flight path. After use, drain and flush sprayer with water.

Compatibility
Larvin 375 may be mixed with DiPel ES, Delfin WG, most other foliar Bt products, Thiodan EC, Folidol M500, Bayer Chlorothalonil, Folimat, Le-mat, Marlin, Marlin 225 and most EC formulations of profenofos and dimethoate. Larvin 375 is physically compatible with Bulldock Duo, Decis Options, Gemstar, Intrepid, Karate, Karate with Zeon, Marlin, Regent 200SC, Reign and Steward. However, before preparing tank mix combinations, it is advisable to mix a small amount of Larvin 375 with an equal volume of water in a small container and add the other pesticide. Any mixture which curdles, precipitates or greases should not be used.
Larvin 375 may also be mixed with Dithane M-45, Penncozeb 420 SC (up to 1.8 L/ha), Penncozeb 750 DF (up to 1.0 kg/ha) and copper oxychloride, PROVIDING the mixtures are used within 6 hours.
Larvin 375 is NOT compatible with other copper- and manganese-based products, zinc-based products including Dithane DF and Dithane Rainshield, with LV, ULV or other oil-based formulations, or with vegetable oil diluents.
As the formulations of other manufacturers’ products are beyond the control of Bayer CropScience, all mixtures should be tested prior to mixing commercial quantities.

DIRECTIONS FOR USE
Restraints
DO NOT add Larvin 375 to water with a pH below 3.0 or above 8.5.
DO NOT store prepared spray mixture for longer than 6 hours.

BRASSICA CROPS
Pest:
Cabbage cluster caterpillar (Crocidolomia pavonana), cabbage white butterfly (Pieris rapae)
State: All states
Rate: 1.0 to 2.0 L/ha
WHP: 7 days (H), 21 days (G)
Critical comments: Spray as required depending upon pest pressure. Closely monitor pest populations. Use the lower rate for small caterpillars and the higher rate for advanced caterpillars. Add a non-ionic wetting agent at the recommended rates.

COTTON
Pest:
Heliothis (budworms) (Helicoverpa spp.)
State: Qld, NSW, WA, NT only
Rate: 2.0 or 2.5 L/ha
500 mL to 1.0 L/ha PLUS the registered rate of a compatible larvicide
WHP: 21 days (H & G)
Critical comments: This product has ovicidal and larvicidal activity. Ovicidal and Larvicidal Rate: Application should be made on eggs, very small or small larvae only. The most effective timing is on egg hatch. Use the lower rate on light to moderate infestations, and the higher rate on heavier infestations. Closely monitor pest populations after application. Ensure thorough coverage of target areas. Larvae must feed on treated area in order to achieve effective control. Larger larvae and larvae feeding within bolls and squares may not be controlled.
Ovicidal Rate: Ovicidal rates of Larvin 375 should only be used in a tank mix with the registered rate of a compatible larvicide. Time application on egg threshold levels prior to hatching and closely monitor the population. Use the lower rate of Larvin 375 where egg pressure is less than 3 eggs per terminal. Use the higher rate of Larvin 375 under higher egg pressure. Repeat application to maintain control. Ensure thorough coverage of target areas.

MAIZE, SWEETCORN
Pest:
Heliothis (Helicoverpa armigera)
State: Qld, NSW, Vic, Tas, WA only
Rate: 1.5 to 2.0 L/ha
WHP:
Maize 7 days (H & G)
Sweetcorn 7 days (H), 21 days (G)
Critical comments: Closely monitor pest populations during tasselling-silking. If high numbers of medium to large caterpillars are in the tassels, spray at tassel emergence. Egg laying is heaviest during green silk formation. Time applications to coincide with egg hatching. Ensure thorough coverage of target areas.

POTATOES
Pest:
Heliothis (budworms) (Helicoverpa spp.)
State: All States
Rate: 1.0 L/ha
WHP: 7 days (H), 21 days (G)
Critical comments: Time application to coincide with egg hatching and closely monitor pest populations. Larvae should be no larger than 2-3 mm in length at application. Ensure thorough coverage of target area. Follow up treatments may be required to
maintain pest control. For resistance management a maximum of 2 applications of group 1A (carbamate) insecticides (e.g. Larvin) is recommended per crop. If an application failure is suspected to be due to insecticide resistance, seek advice from your state agriculture or primary industry department. DO NOT follow up with another application of Larvin 375 or an application from the same insecticide group.
