GENERAL INSTRUCTIONS

DELFIN WG is a biological insecticide based on the SA-11 strain of Bacillus thuringiensis (Bt) subspecies kurstaki (Bt), a spore-forming bacterium that produces crystals of a protein endotoxin. This endotoxin is specifically toxic to lepidopteran larvae.

DELFIN WG acts within the gut of the target larvae, causing feeding inhibition within a few minutes of ingestion. Eventually, disintegration of the gut wall and larval death occur. Dying larvae can be expected to be found for several days after application.

DELFIN WG is a selective agent that provides fast and effective control of lepidopteran larvae without harmful effects on humans, domestic animals, honeybees, wildlife, fish, and beneficials. Thorough spray coverage is essential as DELFIN WG is active only if ingested by the caterpillar. Coverage of the underside of the leaf is important.

Insecticide Resistance Warning

For insecticide resistance management, DELFIN WG is a Group 11C insecticide. Some naturally occurring insect biotypes resistant to DELFIN WG and other Group 11C insecticides may exist through normal genetic variability in any insect population. The effectiveness of DELFIN WG on resistant individuals could be significantly reduced. Certis USA L.L.C. accepts no liability for any losses that may result from the failure of DELFIN WG to control resistant insects.

DELFIN WG may be subject to specific resistance management strategies. For further information, contact your local supplier, Certis USA L.L.C. representative, or local agricultural department agronomist.

Mixing

Half fill the spray tank with water, start agitation. Pour the required quantity of DELFIN WG while maintaining agitation; add other spray material (if any) and add the balance of water. Maintain agitation throughout preparation and spraying operations. Maintain agitation while mixing, standing, and spraying. DO NOT allow diluted sprays to remain in the tank for more than 24 hours.

DELFIN WG is formulated to provide desirable coverage and adhesion on leaf surfaces.

Application

As this product must be ingested, thorough spray coverage is essential. If rain falls shortly after treatment, re-treatment may be necessary. To obtain maximum assistance from beneficial insects, avoid the use of broad-spectrum insecticides during a program of the above sprays. For most consistent control, apply at the first sign of newly hatched larvae. Re-apply as necessary under a pest management program that includes frequent scouting. In situations of dense crop foliage and rapid crop growth, increasing water volumes will provide more complete crop coverage and may improve DELFIN WG performance. During periods of high temperatures, larvae will progress through early instars very rapidly, and early application timing is necessary for control.

To be effective, DELFIN WG spray must be deposited at the larval feeding site. In tomatoes when plant cover is dense and larvae are feeding in the lower 2/3 portion of the plant, aerial application of DELFIN WG may not provide adequate control.

High Volume (Dilute) Sprays: Fully wet plant foliage to the point of run-off and typically utilize a minimum water volume of 1000 L/ha. When using reduced water volumes, increase the rate of DELFIN WG Biological Insecticide to ensure the same total amount of product is applied to the target crop as when applying with higher water volumes.
Broadacre applications: When applying by ground boom spray, use the highest practical water volume. DO NOT apply less than 200 L total spray volume per hectare, unless otherwise stated.
Compatibility

Commonly used acaricides, insecticides, and fungicides are compatible with DELFIN WG if mixed in the spray tank and used promptly. It is recommended to conduct a preliminary compatibility test with the planned mixture to observe the physical aspect of the spray and the reaction it may produce on the plants. Larval behavior may also be modified by some products.

PROTECTION OF LIVESTOCK, WILDLIFE, FISH, CRUSTACEANS, AND ENVIRONMENT

Avoid contamination of any watercourse (ponds, waterways, or drains) during handling, spraying, disposing of the product or its container, and during cleaning of the equipment. DO NOT apply where run-off is likely to occur. DO NOT apply when weather conditions favor drift from areas treated.

STORAGE AND DISPOSAL

KEEP OUT OF REACH OF CHILDREN. Store in the closed, original container in a dry, cool, well-ventilated area out of direct sunlight. As DELFIN WG is a biological insecticide, it can be damaged by heat and should be protected at all times from high temperature. Single rinse before disposal. Add rinsings to the spray tank. DO NOT dispose of undiluted chemicals on-site. Puncture and bury empty bags in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation, and tree roots. Empty bags and product should not be burnt.

SAFETY DIRECTIONS

Will irritate the eyes and skin. Avoid contact with eyes, skin, and open wounds. DO NOT inhale spray mist. When opening the container and preparing spray wear:

cotton overalls buttoned to the neck and wrist;
a washable hat;
elbow-length PVC gloves; and
face shield or goggles.
If the product is on the skin, immediately wash the area with soap and water. If the product is in the eyes, wash it out immediately with water. After use and before eating, drinking, or smoking, wash hands, arms, and face thoroughly with soap and water. After each day's use wash gloves, face shield or goggles, and contaminated clothing.
