GENERAL INSTRUCTIONS

Rygel Bifenthrin 100EC Insecticide/Miticide is a contact and residual insecticide/miticide. It can be used as a protective treatment when applied at regular intervals or as a knockdown treatment to control existing pests. Best results are obtained when Rygel Bifenthrin 100EC Insecticide/Miticide is applied before pest populations build up to damaging levels. This product is not suitable for use in Integrated Pest Management (IPM) programs where mite or other insect predators or parasites are established and providing effective mite and other insect control.

APPLICATION

Rygel Bifenthrin 100EC Insecticide/Miticide may be applied by either ground rig or aircraft. Thorough coverage is essential to ensure adequate control. Do not apply as a fog or mist.

Dilute Spraying:

• Use a sprayer designed to apply high volumes of water up to the point of run-off.
• Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of run-off. Avoid excessive run-off.
• The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from industry guidelines or expert advice.
• Add the amount of product specified in the Directions for Use table for each 100L of water. Spray to the point of run-off.
• The required dilute spray volume will change as the sprayer set up and operation may also need to be changed as the crop grows.

Concentrate Spraying:

• Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of run-off) and matched to the crop being sprayed.
• Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.
• Determine an appropriate dilute spray volume (See Dilute Spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate.
• The mixing rate for concentrate spraying can then be calculated in the following way: EXAMPLE ONLY: i) Dilute spray volume as determined above: For example 1000L/ha. ii) Your chosen concentrate spray volume: For example 500L/ha iii) The concentration factor in this example is: 2 X (i.e. 1000L + 500L = 2) iv) If the dilute label rate is 50mL/100L, then the concentrate rate becomes 2 x 50, that is 100mL/100L of concentrate spray.
• The chosen spray volume, amount of product per 100L of water, and the sprayer set up and operation may need to be changed as the crop grows.
• For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

Ground Application:

Applications should be made as a fine spray preferably using hollow cone nozzles and a droplet size of 150 to 200 microns. The application volume will depend on the type of crop to be treated. The following are suggested:

Low volume broad acre applications to - e.g. cereals, canola, grain legumes, lucerne, subterranean clover: 50-200L/ha. Low volume row crops applications to cotton, tomatoes, navy beans: 50-200L/ha. High volume applications to row crops - e.g. trellised tomatoes: 200-1000L/ha except as noted in critical comments. Use 200L/ha from transplanting increasing to 1000L/ha at maturity. High volume directed spray:

Grapes: Apply by hand application, using a high volume coarse spray of 500mL/vine. (e.g. at approx. 2500 vines/ha = 1250L/ha). Foliar sprays to bananas: 300 to 500L/ha. High volume application to stone fruit: 1000 to 2000L/ha.

Soil Applied Sprays:

High volume application:

Bananas: Stool treatment: Apply as a coarse spray at 500-750mL per stool. Band treatment: Apply as a band application with a side delivery boom and offset nozzles - 1 L of spray solution per stool. Citrus: Apply as a high volume, directed spray to the ground under each tree. For optimum control apply to both sides of the tree. Total spray volume should be 5 to 10L/tree (e.g. at 250 trees/ha = 1250 to 2500L/ha).

In furrow applications:

Cotton & Sugarcane: Use a coarse spray: 60 to 100L/ha as a band over the seed or sett before covering with soil - refer to critical comments for details.

Aerial Application:

Use at least 20L/ha of total spray volume. Spray during the cooler parts of the day or night. To reduce the possibility of drift, avoid spraying in calm conditions or when the wind is light and variable. Preferably, spray in a crosswind. Use suitable application equipment and/or nozzles to deliver a fine spray with a droplet size of 150 to 200 microns. A spray drift minimization strategy should be employed at all times when aerially applying sprays to, or near, sensitive areas. The strategy envisaged is best exemplified by the cotton industry's Best Management Practice manual.

MONITORING

Post-emergence monitoring of Citrus leaf-eating weevil populations: At the first sign of major beetle emergence in mid-October, commence monitoring at 1 to 2 week intervals. Place a polystyrene fruit box (330 x 480mm) under the tree, shake branches vigorously, repeat on ten randomly selected trees throughout the orchard. If 25 beetles or more are recorded in consecutive counts, treatment is required.

MIXING

Add the required quantity of Rygel Bifenthrin 100EC Insecticide/Miticide to water in the spray tank and mix thoroughly. Maintain agitation during mixing and application.

COMPATIBILITY

Rygel Bifenthrin 100EC Insecticide/Miticide is compatible with commonly used fungicides such as Dilthane M45, Antracol, Chlorothalonil 500, and the herbicides - Sprayseed, Broadstrike, Spinnaker, Simazine 900, Dual, Metribuzin, Chlorsulfuron, Triasulfuron, and Pendimethain.

SURFACTANTS

Rygel Bifenthrin 100EC Insecticide/Miticide contains a surfactant. Additional surfactant may only be necessary on hard to wet plants and in high volume situations.

NOTICE

Helicoverpa (= Heliothis) armigera resistance in Northern NSW and Qld. To help contain pyrethroid resistance in H. armigera, the Summer Crop Insecticide strategy as developed by the Qld Department of Primary Industries and NSW Agriculture should be adhered to. Failure to observe the strategy may result in widespread resistance affecting the future viability of summer cropping.
