GROUP 3A INSECTICIDE

For the control of Heliothis (Helicoverpa spp.) and other specified pests on cotton and various other crops as per the DIRECTIONS FOR USE Table.

GENERAL INSTRUCTIONS
Insecticide Resistance Warning
For insecticide resistance management, Decis Options Insecticide is a Group 3A insecticide.
Some naturally occurring insect biotypes resistant to Decis Options and other Group 3A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Decis Options or other Group 3A insecticides are used repeatedly. The effectiveness of Decis Options 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 Decis Options to control resistant insects.
The user should seek advice, and monitor the performance, and if the results are not in accordance with expectations, contact the manufacturer immediately. Apparent resistance however, should not be confused with poor application, coverage or timing techniques.
Decis Options 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 Decis Options. 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 Decis Options.

Application and Equipment
Decis Options is a contact spray. Thorough, even coverage is essential. Residual control of Decis Options may be reduced if heavy rainfall is received within 48 hours of application. Decis Options can be applied using water as a carrier, and from aircraft can also be applied ULV when in combination with a compatible ULV insecticide and/or oil as bulking agent.
Ground Spray
Standard low volume boom or high volume equipment may be used.
Aircraft
Applied with water - Decis Options may be applied by aircraft using water as a carrier. Water volumes of 20 to 30 L/ha have given satisfactory results.
Applied ULV - Decis Options may also be used without dilution in mixture with some ULV products, as listed under Compatibility, or applied ULV in combination with D-C-Tron® Cotton Spray Oil, D-C-Trate® Anti-Evaporative Spray Oil or Ulvapron® Oil. A minimum spray volume, as described in the table below, should be applied ULV, using either a compatible ULV insecticide mixture partner and/or compatible oil as the bulking agent.
DO NOT add water – use direct from the container.

Compatibility
Applied with water - Decis Options may be mixed with most piperonyl butoxide formulations and most formulations of fungicides and insecticides such as chlorothalonil, dimethoate, mancozeb, metalaxyl, methomyl, pirimicarb, Larvin® 375, Ovasyn® Options, where these products are required for additional insect control or for control of diseases. Decis Options may also be mixed with other products including Wuxal® Liquid Foliar Nutrient and most knockdown herbicides.
Applied ULV - When sprayed as a ULV product, Decis Options is compatible with Ovasyn Options, where this product is required for additional insect control. Decis Options is also compatible with D-C-Tron Cotton Spray Oil, D-C-Trate Anti-Evaporative Spray Oil and Ulvapron Oil. For further information on ULV insecticide compatibilities contact Bayer CropScience Pty Ltd. Warning: Decis Options may be mixed with some organophosphate insecticides for additional insect control. Organophosphate insecticides can cause phytotoxicity, which may be exaggerated with multiple applications. The addition of Decis Options to organophosphate insecticides does not affect the degree of phytotoxicity.
Warning: Decis Options may be mixed with some organophosphate insecticides for additional insect control. Organophosphate insecticides can cause phytotoxicity, which may be exaggerated with multiple applications. The addition of Decis Options to organophosphate insecticides does not affect the degree of phytotoxicity.

Mixing
Applied with water - Fill the spray tank to about ¾ full with clean water. Add the required quantity of Decis Options to the spray tank with agitators in motion. Where other products are to be mixed, add these after Decis Options is mixed in the tank. Top up the spray tank to the required volume with clean water, with agitators operating.
Applied ULV - When Decis Options is to be applied as a ULV spray in combination with compatible ULV products (or oil), Decis Options should be added after the ULV product (or oil), with agitators in motion. Ensure that there is no water, or products containing water, in this mixture, or in the spraying equipment.

Pest: Corn earworm and native budworm (heliothis)
State: All States
Rate: 250 to 500 mL/ha
WHP: 7 day
Critical comments: 
Inspect crops regularly and particularly at flowering and early podding. Apply as soon as infestation occurs. Use lower rates only when infestation is low and majority of larvae are young (i.e. less than 5 mm). Large larvae are often not readily controlled.
