Steward® eVo insecticide is an oxadiazine insecticide in the form of an emulsifiable concentrate. Steward® eVo insecticide is to be mixed in water and applied as a foliar spray for control of diamondback moth and cabbage white butterfly in vegetable brassicas, and soybean looper in outdoor lettuce. Steward® eVo 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.
Steward® eVo insecticide has been specifically designed for use in Integrated Pest Management programs. 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. Steward® eVo insecticide does not give traditional larval “knockdown” control.
Steward® eVo insecticide is compatible with many commonly used fungicides, liquid fertilisers, herbicides, insecticides, and biological control products. However, since the formulations of products are always changing, it is advisable to test the physical compatibility of desired tank mixes and check for adverse effects like settling out or flocculation. To determine the physical compatibility, add the recommended proportions of the tank mix products to water, mix thoroughly and allow to stand for 20 minutes. If the combination remains mixed, or can be re-mixed readily, it is considered physically compatible. Avoid complex tank mixtures of several products or very concentrated spray mixtures.
The crop safety of all potential tank-mixes, including additives and other pesticides, on all crops has not been tested. Before applying any tank-mixture not specifically recommended on this label or other FMC supplemental labelling, the safety to the target crop must be confirmed. To test for crop safety, apply the combination to a small area of the target crop in accordance with the label instructions to ensure that a phytotoxic response will not occur.
The mixing sequence recommended is: water-soluble bags, water-soluble granules, dry flowable or water-dispersible granules, wettable powders, water-based suspension concentrates, water-soluble concentrates, suspo-emulsions, oil-based suspension concentrates, emulsifiable concentrates (e.g. Steward® eVo insecticide), adjuvants and surfactants, soluble fertilisers and drift retardants.
Insect Resistance Warning
Steward® eVo insecticide contains indoxacarb, a Group 22A insecticide. Unless directed otherwise in the specific crop/insect sections of the label, the following practices are recommended to prevent or delay the development of insecticide resistance to Steward® eVo insecticide and to Group 22A insecticides;
- Apply Steward® eVo insecticide or other Group 22A insecticides using a “window” approach to avoid exposure of consecutive insect pest generations to the same mode of action. Multiple successive applications of Steward® eVo insecticide are acceptable if they are used to treat a single insect generation.
- Following a “window” of Steward® eVo insecticide or other Group 22A insecticide, rotate to a “window” of applications of effective insecticides with a different mode of action.
- The total exposure period of all “Group 22A-active windows” applied throughout the crop cycle (from seedling to harvest) should not exceed 50% of the crop cycle.
- Incorporate IPM techniques into the overall pest management program.
- Monitor insect populations for loss of field efficacy.
Steward® eVo insecticide may be subject to alternative resistance management strategies, refer to http://resistance.nzpps.org for specific pest strategies.
If you experience difficulty with control and resistance is a reasonable cause, immediately consult your local farm chemical supplier, consultant, or local FMC representative for the best alternate method of control for your area.
Since the occurrence of resistant individuals is difficult to detect prior to use FMC accepts no liability for any losses that may result from the failure of Steward® eVo insecticide to control resistant insects.

Spray equipment must be clean and free of previous pesticide deposits before applying Steward® eVo insecticide. Fill spray tank ¼ to ½ full of water. Measure the amount of Steward® eVo insecticide required for the area to be sprayed. Add Steward® eVo insecticide directly to the spray tank with the agitation engaged. Mix thoroughly to disperse the insecticide. Once dispersed, the material must be kept in suspension at all times by continuous agitation. Use mechanical or hydraulic means, DO NOT use air agitation, premix or slurry.
Use the prepared spray immediately. If unforeseen conditions prevent immediate use of the Steward® eVo insecticide spray mix, the mix may be stored up to 72 hours. Before use, thoroughly agitate the spray mix until fully resuspended. Mixtures containing Steward® eVo insecticide should not be stored.
Ground application: Use enough water to ensure thorough coverage of the crop. Adjust water volumes to
crop stage (200 – 800 L/ha).
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.
Use a boom sprayer fitted with high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger droplets. Use the lower spray pressures recommended for the nozzle. 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. Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles produce larger droplets. Consider using low-drift nozzles. When applying Steward® eVo insecticide by ground application, keep the boom low to avoid spray drift.
Minimising Spray Drift: The interaction of many equipment and weather-related factors determines the potential for spray drift. The applicator must consider all these factors when making application decisions. The most effective way to reduce drift potential and maintain efficacy is to apply a volume mean diameter (VMD) 285 - 300 microns.
DO NOT apply when wind speed is less than 3 or more than 20 kilometres per hour at the application site. DO NOT apply by air.
Sprayer Clean Out
Prior to application, start with clean, well-maintained application equipment. Immediately following application, thoroughly clean all spray equipment to reduce the risk of forming hardened deposits which might become difficult to remove. Drain spray equipment. Thoroughly rinse sprayer and flush hoses, boom, and nozzles with clean water.
Clean all other associated application equipment. Take all necessary safety precautions when cleaning equipment. DO NOT clean near wells, water sources or desirable vegetation. Dispose of waste rinse water in accordance with local regulations.
Storage & Disposal
Store in original container, tightly closed and under lock and key. DO NOT store with Class 1, 2, 3.2, 4 or 5 substances or feed, seeds or foodstuffs. Stores containing more than 100 kg of this product require secondary containment and are subject to signage. When stored appropriately, this product should show no significant degradation for 2 years from the date of manufacture. Contact your supplier for further information about the use of any product that is older than this.
Container disposal: Triple rinse container and add rinsate to spray tank. Burn, if circumstances, especially wind direction permit, otherwise bury in an approved landfill. DO NOT reuse container.
