DU PONT - insecticide
59573

For the control of various species of insect pests in Azuki beans, Chickpeas, Cotton, Faba beans, Mungbeans and Soybeans as per the Directions for Use.

GENERAL INSTRUCTIONS
DuPont™ Steward® EC insecticide is an emulsifiable concentrate formulation.
DuPont™ Steward® EC insecticide should be applied after careful field monitoring of pest populations of eggs and larvae to determine the need for application, the correct timing of the initial application and of any subsequent applications. For Cotton only, subsequent applications are dependent on economic thresholds, as well as the growth rate of new unprotected cotton terminals.
For Helicoverpa species, spray applications should be timed to coincide with egg hatching and before larvae are entrenched in protected feeding sites.
DuPont™ Steward® EC has been specifically designed for use in Integrated Pest Management schemes. The active ingredient, indoxacarb enters larvae primarily by ingestion of treated foliage, or through penetration of the insect cuticle. After ingesting indoxacarb, the larvae cease feeding and die three to five days later. DuPont™ Steward® EC does not give traditional larval “knockdown” control but controls nominated larvae species giving superior:
• square, flower and boll protection in cotton OR
• foliage, flower and pod protection in Chickpea, Faba beans, Mungbeans or Soybeans

INSECTICIDE RESISTANCE WARNING
For insecticide resistance management DuPont™ Steward® insecticide is a Group 22A insecticide.
Some naturally occurring insect biotypes resistant to DuPont™ Steward® and other Group 22A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if DuPont™ Steward® or other Group 22A insecticides are used repeatedly. The effectiveness of DuPont™ Steward® on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, DuPont accepts no liability for any losses that may result from the failure of [trade name] to control resistant insects.
Strategies to minimise the risk of insecticide resistance are available. To help prevent the development of resistance to Steward® EC insecticide observe the following instructions:
• Use Steward® EC insecticide in accordance with the current Insecticide Resistance Management (IRM) strategy for your region.
• Cultivate all cotton fields as soon as possible after picking to destroy overwintering pupae of Helicoverpa armigera.
For further information contact your local supplier, DuPont representative or local agricultural department agronomist. 

PRODUCT USE
The interaction of equipment and weather-related factors determines the potential for spray drift. The applicator must consider all these factors when making application decisions and determining off-target drift risks near the application. A spray drift minimisation strategy, should be employed at all times when applying this product.
APPLYING LARGER DROPLETS (volume median diameter (VMD) 150-250 microns) REDUCES DRIFT POTENTIAL, BUT WILL NOT MINIMISE DRIFT IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER UNFAVOURABLE ENVIRONMENTAL CONDITIONS. Larger droplets may reduce the effects of evaporation.

Mixing
Use only clean water. Half fill the spray tank with water and add the appropriate amount of Steward® EC insecticide directly to the spray tank, agitate and add Ovasyn‡ or amitraz 200 g/L EC, (if applicable), then completely fill the tank. Mix thoroughly and continue mechanical or hydraulic agitation.

Storage of spray mixture
Use the prepared spray immediately. If unforeseen conditions prevent immediate use of the Steward® EC insecticide spray mix, the mix may be stored up to 72 hours. Before use, thoroughly agitate the spray mix until fully resuspended. Mixtures of Steward® EC insecticide plus Ovasyn‡ or Amitraz 200 g/L EC should not be stored.

Application
Application equipment should be calibrated to apply at least sixty (60) droplets per cm2 of target foliage. Droplet VMD should be of medium spray quality according to ASAE S572 definition for standard nozzles.

Ground application
Apply as a blanket spray or as a banded spray to all crops. Ensure thorough spray coverage on the foliage, using appropriate fan nozzles. Apply in a minimum spray volume of 100 L/ha and keep the boom low to avoid spray drift. A minimum spray pressure of 275 kPa (40 psi) should be used with fan nozzles applying insecticides. Higher pressure reduces droplet size, DOES NOT improve canopy penetration and may increase drift potential. WHEN HIGHER FLOW RATES ARE NEEDED, USE A HIGHER-CAPACITY NOZZLE INSTEAD OF
INCREASING PRESSURE. For band spraying, increase the number of fan nozzles per crop row as the plant size increases.

Aerial application
DuPont™ Steward® EC must only be applied with aircraft fitted with accurately calibrated equipment. Apply a minimum total spray volume of 30 L/ha with nozzles (e.g. Micronaire‡ rotary atomisers, CP nozzles or conventional hydraulic nozzles) set to medium spray quality according to ASAE S572 definition for standard nozzles. A spray drift minimisation strategy, should be employed at all times when applying this product. DO NOT apply Steward® EC using Ultra Low Volume (ULV) methods.

Compatibility: Label instructions for all products must be observed
Steward® EC is compatible with Ovasyn‡ insecticide, Amitraz‡ 200 g/L EC formulations and Pix‡ (mepiquat chloride). Steward® EC is not compatible with ultra low volume (ULV) formulations or the
following foliar fertilisers: Supa‡ K 30, Zip‡ and Triple 7‡. Since formulations may be changed and new ones introduced, it is recommended that users pre-mix a small quantity of the desired tankmix and observe possible adverse changes (settling out, flocculation etc).

Salt
When the addition of salt is indicated in the Directions for Use table, DuPont recommends the use of salt from the following sources: Table or cooking salt, Pool salt, or salt approved for use in livestock feed e.g. Cheetham‡ RAM (No. 2) Dried Fine Salt, Olsson’s‡ Kiln Dried Course Refined Salt.

Spray Equipment Cleanout
Only apply product using clean, well maintained equipment. Immediately following application, thoroughly clean all spray equipment to reduce risk of deposits forming that might become difficult to remove.
Drain spray equipment into a disposal pita designed for this purpose. Thoroughly rinse sprayer and flush hoses, boom, and nozzles with clean water. Fill the sprayer with clean water and household ammonia (one litre of 3 active for every 100 L of water). Flush hoses, boom, and nozzles. Turn off boom and top off the tank with clean water. Circulate through the spraying system for at least 15 minutes. Flush the hoses, boom and nozzles and drain the tank. Remove and clean nozzles, screens, and strainers in a bucket of fresh ammonia and water. Thoroughly rinse the sprayer, hoses, boom and nozzles with clean water several times. Clean all other associated contaminated application equipment.

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS
DO NOT apply under weather conditions, or from spraying equipment, that may cause spray to drift onto nearby non-target plants/crops, cropping lands or pastures.
Refer to the Product Use section above and the cotton industry’s Best Management Practice Manual to manage spray drift during application.

PRECAUTION
DO NOT use human flaggers/markers unless they are protected by engineering controls such as vehicles with enclosed cabs.
