Chemical Group synthetic pyrethroid
Mixing: Shake well before use
For ground or aircraft application with water: Cyhella mixes readily with hard or soft water. Add the required quantity of product to water whilst under agitation to ensure thorough mixing. Agitate while spraying. It is not advisable to allow the mixed solution to stand longer than 24 hours before use. In extremely alkaline water (pH 9) spray immediately after mixing.
For ULV (Ultra Low Volume) application with oil: It is recommended that Cyhella is mixed with a mineral spraying oil. See compatibility section for list of recommended mineral spraying oils. Add the required quantity of product to oil whilst under agitation to ensure thorough mixing. Agitate while spraying. It is not advisable to allow the mixed solution to stand longer than 24 hours before use.
Good coverage is essential to ensure adequate control. The product may be applied by ground rig or aircraft.
Acceptable threshold values for eggs and larval numbers may vary according to the stage of the crop development and the pest management program under-taken. Alternative higher thresholds may be acceptable under certain circumstances.
Diluted with water: For ground rigs the volume of liquid applied should be 50 to 100 L/ha. Aerial application should be under conditions normally suitablle for water based insecticides. Apply in at least 10 to 20 litres of water per hectare.
Mixed with oil: Apply the recommended rate of Cyhella bulked with oil to total volume of 3 to 5 L/ha for cotton, sorghum and sunflowers. The total volume for all other crops should be 1.5 litres per hectare.
This product is a contact and residual insecticide. Best results will be obtained if Cyhella is applied as a protective treatment at regular intervals. However if spraying frequency is based on scouting, then for Helicoverpa spp application at egg hatch will give optimum results.
Frequent and thorough checking of whole plants, terminals, squares, flowers, bolls or fruiting bodies as required, should be made over a random sample of plants, representative of the whole crop area.
Inspect crops after spraying to ensure a thorough kill has been obtained, however note that maximum kill may not be achieved until 48 hours after treatment. Then check at frequent intervals, not more than 2 days apart when insect pressure is heavy. Apply the recommended treatment as soon as a crop check indicates spraying is necessary.
Insecticide Resistance Warning
For insecticide resistance management Cyhella is a Group 3A insecticide.
Some naturally occurring insect biotypes resistant to Cyhella 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 Cyhella or other Group 3A insecticides are used repeatedly. The effectiveness of Cyhella on resistant indiviuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Zelam Pty Ltd accepts no liability for any losses that may result from the failure of Cyhella to control insects.
Cyhella may be subject to specific resistance management strategies. For further information contact your local supplier, Ospray Pty Ltd representative or local agricultural department agronomist.
Helicoverpa armigera (Heliothis) resistance in Nth NSW and Qld: To help contain pyrethroid resistance in H. armigera, the Summer Crop Insecticide Strategy as developed by AIRAC, Qld Department of Primary Industries and the NSW Department of Agriculture and Fisheries should be adhered to. Failure to observe the strategy may result in widespread resistance affecting the future viability of summer cropping.
This product, when applied as a water based spray is compatible with the following actives (products): Pirimophos methyl (Actellic® 900SF), procymidone (Fortress), fluazifop-P-butyl (Fusilade), paraquat (Gramoxone), primicarb (Pirimor), paraquat plus diquat (Spray.Seed), and glyphosate.
Human flagging is not supported unless flaggers are protected by engineering controls such as vehicles with cabs.
Do not allow entry into treated fields/crops until the spray has dried. If prior entry is necessary, wear cotton overalls and chemical resistant gloves.
Protection of Wildlife, Fish Crustaceans and Environment
Dangerous to fish and aquatic organisms. DO NOT conatminate streams, rivers or waterways with the product or the used containers. Tail waters which flow from treated areas should be prevented from entering river systems. A strategy to minimise spray drift should be employed at all times when aerially applying sprays near sensitive areas. Such a strategy is illustrated by the cotton industry's Best Management Practice Manual.
Protection of Livestock
Toxic to bees. DO NOT spray when bees are actively foraging. Risk is reduced by spraying in the early morning or late evening.
Storage and Disposal
Store in the closed, original container in a cool, well-ventilated area. Do not store for prolonged periods in direct sunlight. Store in a locked room or place away from children, animals, food, feedstuffs, seed and fertilisers. Triple or preferably pressure rinse empty containers before disposal or recycling. Add rinsings to spray tank. DO NOT dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the containers below 500mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots in compliance with Local, State or Territroy government regulations. Empty containers and product should not be burnt.
Harmful if inhaled or swallowed. Will irritate the eyes and skin. Repeated exposure may cause allergic disorders. Facial skin contact may cause temporary facial numbness. Avoid contact with eyes and skin. When opening the container, preparing spray and using the prepared spray wear cotton overalls buttoned to the neck and wrist, a washable hat, elbow-length PVC gloves and face shield. If product on skin, immediateliy wash area with soap and water. Wash hands after use. After each day's use, wash gloves, face shield and contaminated clothing.
